I get
Running `brew update --auto-update`...
Error: Because of the limitation of build system, there is no cask support for Catalina(10.15) and earlier, please build from Homebrew formula.
from the command brew upgrade. How should I proceed?
If I understand correctly (which I'm not sure I do), some of the packages I have installed do not support cask any longer. If so, I would identify those packages, remove them, and install the corresponding formulae (if available), but I don't know which packages are causing this error.
Edit: brew doctor doesn't say anything about the above problem.
I had the same problem. Googling brought me to your post, as well as this line in railwaycat/homebrew-emacsmacport. brew tap included it in the list.
brew untap railwaycat/emacsmacport
fixed it for me. I hope it does for you!
I made a GitHub issue for the problem.

Is there a way to install Valgrind on Catalina and have it run properly? If so, I would very much appreciate a step-by-step process.
I tried installing Valgrind with https://github.com/sowson/valgrind
but when I tested out helloWorld.cpp on the terminal, the console returned errors I should not have gotten.
I'm not sure if I committed an error on my part in the installation process of this version of Valgrind or if Valgrind itself is simply incompatible with Catalina OS.
I have also tried installing Valgrind via Homebrew, but I've had issues with that as well (github.com/Homebrew/homebrew-core/issues/36683).
Currently, no. The repo you link has an issue raised about Catalina compatibility. As you also show, the brew package has its own problems as well. Official valgrind only supports 10.12.
You'll just have to wait, or containerize it. Although if you containerize valgrind, you would likely need a compatible build container as well.
Ok. I've found a way to use Valgrind on Catalina. Here's a link to my guide for how https://github.com/john-yohan-park/Valgrind_Catalina
Works amazingly!! see https://github.com/LouisBrunner/valgrind-macos/issues/5.
Not Homebrew, you need to compile it from source, but it's not so difficult.
1. git clone https://github.com/LouisBrunner/valgrind-macos.git
2. cd valgrind
3. sudo ./autogen.sh
4. sudo ./configure --prefix=/where/you/want/it/installed --enable-only64bit
5. copy the [contents][1] to ./coregrind/m_mach/mach_basics.c
6. sudo make
7. sudo make install
enjoy!
This is how I just did it on Catalina 10.15.5:
brew remove valgrind # remove previous attempts at installing it (if any)
brew tap LouisBrunner/valgrind
brew install --HEAD LouisBrunner/valgrind/valgrind
Source: https://github.com/LouisBrunner/valgrind-macos
Maybe someone else asked the same question too. But this question is difficult. I tried everything. The place I am stuck is with installing dependencies. Some of the dependencies are old and not easily available. But I managed to install them.
The problems lies here.. There are dependencies that need to get the build from their source code. I already installed Visual C++ Build and MSMPI. Also installed HDF5 for H5PY but it doesn't let me build old versions of H5PY. So, I tried installing the latest version of H5PY but still, I am stuck at errors like file not found. Some of the files which the build process cannot find are "h5py/h5f.pyx", "mpi_c", "mpi.h". Solving error for one missing file leads to other and so on..
On trying hard to solve such errors and installing one or the other package to do the same task, I am tired up.. Something I found, at last, was that "mpi_c" file was replaced with some other file in newer versions of MPI4PY. But my dependencies depend on older version. I tried installing an older version of MPI4PY but HDF5 won't let me install that giving other errors. At last, I quit the task with my whole day wasted after this.
So can someone here please provide a step by step guideline for installing Rasa Stack on Windows Machine?
Windows 10 with Python 3.7.. Let me know if I need to downgrade python as well.. It was my first time building some project from source with python on windows. Thanks...
Please try the below steps to install Rasa:
Install Conda
Create a virtual environment:
conda create -n myenv python=3.5
Activate the virtual environment
conda activate myenv
pip install rasa_nlu rasa_core
Having successfully installed opam and having switched to 4.01.0 version of compiler I am struggling to install utop. Installation is failing at 'conf-ncurses.1' step.
Running 'opam depext' does not reveal much, saying that 'no extra dependencies' need to be installed. Switching to latest stable compiler, and then installing utop fails with the same problem. The *.err and *.out files are empty, hence not revealing any problem.
On my box I also have ncurses-devl and pkgconfig installed (see rpm output below)
Below is the screenshot of what I can see (hopefully it give us enough information). Any ideas where to look at ?:
Screehshot
First of all, SO is not an issue tracker and it is better to report this issue to the package maintainers. The following command will reveal URLs for the issue trackers:
opam show conf-ncurses | grep bug-reports
opam show utop | grep bug-reports
Second, your output is not at sync with what I'm seeing in the opam-repository. At the current HEAD there is no check pkg-config ncurses at all, as it was removed three days ago. So, if you indeed have ncurses-devel package installed, then you need just to update opam, with
opam update
I am using a virtualenv for a django setup. I am trying to build a view that pulls data from logs and then graphs the data. Eventually I would like to have this real-time and live. If you have any recommendations on other solutions that would suit my project best, please do not hesitate to include them in the comment fields below.
I have attempted to install matplotlib from pip using pip install matplotlib.
I receive the following message:
* The following required packages can not be built:
* freetype
I then validated that it was installed
yum install freetype
Package freetype-2.3.11-14.el6_3.1.x86_64 already installed and latest version
I then found that there is a python-matplotlib which is an older version .99. However, I want to keep this inside of the virtual environment and not system wide.
find / -name *freetype*
/var/lib/yum/yumdb/f/d2807dcfe3762c0b9f8ef1d9bf0f05788e73282a-freetype-2.3.11-14.el6_3.1- x86_64
/usr/lib64/libfreetype.so.6.3.22
/usr/lib64/libfreetype.so.6
/usr/share/doc/freetype-2.3.11
I searched all over stackoverflow and only saw solutions for ubuntu which did not transfer over to centos.
Thank you for your time,
John
pip is going to compile matlibplot on your local machine, so you'll need freetype development headers installed as well.
CentOS 6+, Fedora, etc.:
$ sudo yum -y install freetype freetype-devel libpng-devel
On older operating systems (e.g. CentOS 5), you may run into a more specific freetype versioning issue with newer releases of matlibplot. If you're version agnostic, sticking with a legacy 1.3.x release will negate these dependency issues:
$ pip install matplotlib==1.3.1
Please note, you may need to downgrade your numpy to 1.8 in order to make matplotlib 1.3 work.
$ pip install numpy==1.8
Good luck!
I have just had a similar (albeit not exactly the same) situation. I'll write it up here as this page comes up among the first search results.
CentOS 5
pip install matplotlib complains about freetype
Both freetype and freetype-devel are installed.
~/.pip/pip.log provides the explanation of the problem. There is the line:
freetype: no [Requires freetype2 2.3 or later. Found 2.2.1.]
Obviously, the solution is either to upgrade freetype or downgrade matplotlib.
The second is easier (assuming I am OK with the older version).
pip install matplotlib==1.3.1 works fine.
On the matplotlib installation, this is what I did. Not sure if this is going to help you. Just followed the steps here:
http://pkgs.org/centos-6/centos-x86_64/python-matplotlib-0.99.1.2-1.el6.x86_64.rpm.html
I did not use pip, btw and have CentOS 6.4.
I had this happen to me in two different situations, see if yours is one of them:
freetype was installed, but not in the $PATH yet. Just exiting the shell and starting a new one fixed this.
I was building matplotlib from source, and trying to build from the master branch. After I switched to v1.3.x it correctly detected freetype.
I am tearing my hair out trying to install Spatialite for GeoDjango!
I am already using Homebrew, it's generally easy and convenient so I initially tried to follow the Homebrew instructions for GeoDjango.
But this stops short of installing any database, i.e. Spatialite. The next step is to try and install Spatialite itself, but there are no Homebrew-specific instructions provided by Django docs.
I found this tutorial which looks perfect - a Homebrew and virtualenv-friendly install of Spatialite for GeoDjango.
But it doesn't work... it appears that my pysqlite is linked against the non-spatial-enabled version of SQLite that comes with OS X, rather than the Spatial-ised one I installed from Homebrew, I get this error when Django tried to connect to the db:
"The pysqlite library does not support C extension loading. Both SQLite and pysqlite must be configured to allow the loading of extensions to use SpatiaLite."
The author of pysqlite hasn't responded to my pleas for help on Github and I haven't found anything via Google.
So I went back to the drawing board and decided to follow the "Mac OS X-specific instructions" in the GeoDjango docs... by installing the various geo libs from the KyngChaos binary packages.
The docs say "Install the packages in the order they are listed above" but I found I couldn't install UnixImageIO without installing PROJ first. The link in the docs to download Spatialite binaries (http://www.gaia-gis.it/spatialite-2.3.1/binaries.html) is broken so I used the "Spatialite Tools v4.1" from KyngChaos instead.
Proceeding to the next step I get this error:
$ spatialite geodjango.db "SELECT InitSpatialMetaData();"
SQLite header and source version mismatch
2013-10-17 12:57:35 c78be6d786c19073b3a6730dfe3fb1be54f5657a
2013-09-03 17:11:13 7dd4968f235d6e1ca9547cda9cf3bd570e1609ef
Not really sure what's wrong at this point.
There is someone else here on SO who has gone the KyngChaos route and just ends up with the same "Both SQLite and pysqlite must be configured to allow the loading of extensions" error I got from the Homebrew route anyway.
I found this ticket #17756 for adding pyspatialite support to Django - pyspatialite is supposed to be an easier way to pip install everything but unfortunately it doesn't work either (see comments towards bottom of ticket).
I'm a bit reluctant to start trying to build everything from source by hand as it seems likely I'll just run into the same problems again, but spending hours Googling for info about cryptic compiler errors, magic flags and paths etc along the way.
I'm about ready to give up and just use Postgres/PostGIS.
I was able to get this working now, using the tip here:
https://github.com/ghaering/pysqlite/issues/60#issuecomment-50345210
I'm not sure if it was using the real paths that fixed it, or just the Homebrew kegs or underlying packages have been updated and now install cleanly. Still, it works now.
I reproduce below the steps I took:
brew update
brew install sqlite # 3.8.5
brew install libspatialite # 4.2.0
brew install spatialite-tools # 4.1.1
git clone https://github.com/ghaering/pysqlite.git
cd pysqlite
(where brew reported I had existing versions I unlinked them and installed the latest as commented above)
then edited setup.cfg to comment out #define=SQLITE_OMIT_LOAD_EXTENSION and specify the paths:
include_dirs=/usr/local/opt/sqlite/include
library_dirs=/usr/local/opt/sqlite/lib
activated the virtualenv where I want it installed, then
python setup.py build
python setup.py install
(build_static still fails with clang: error: no such file or directory: 'sqlite3.c')
(maybe I should have done pip install . as suggested in the github issue)
now the spatialite geodjango.db "SELECT InitSpatialMetaData();" succeeds, albeit with an ignorable error:
InitSpatiaMetaData() error:"table spatial_ref_sys already exists"
i.e. it's probably not even necessary to run that command
When I was istalling this i follow this instructions https://docs.djangoproject.com/en/dev/ref/contrib/gis/install/spatialite/#pysqlite2
pysqlite2
If you’ve decided to use a newer version of pysqlite2 instead of the sqlite3 Python stdlib module, then you need to make sure it can load external extensions (i.e. the required enable_load_extension method is available so SpatiaLite can be loaded).
This might involve building it yourself. For this, download pysqlite2 2.6, and untar:
$ wget https://pypi.python.org/packages/source/p/pysqlite/pysqlite-2.6.3.tar.gz
$ tar xzf pysqlite-2.6.3.tar.gz
$ cd pysqlite-2.6.3
Next, use a text editor (e.g., emacs or vi) to edit the setup.cfg file to look like the following:
[build_ext]
#define=
include_dirs=/usr/local/include
library_dirs=/usr/local/lib
libraries=sqlite3
#define=SQLITE_OMIT_LOAD_EXTENSION
I had the same error: SQLite header and source version mismatch.
For me it was enough to update libsqlite3-dev.
After that invoking $ spatialite geo.db "SELECT InitSpatialMetaData();" creates proper database.
