I'm trying to work through the django tutorial, and seem to have a problem with the django installation (on Windows 7). I've installed Python, and pip, and installed Django via pip, at which point I got this output:
Downloading/unpacking Django

Since the messages were only warnings, I proceeded with trying to run django From within the project folder, I issue:
C:\data\spark2\spark\spark_project>python manage.py runserver
and receive the message:
ImportError: No module named debug_toolbar
then the command prompt is displayed again.
I've tried uninstalling and re-installing Django, to no avail.
Any ideas?
You forgot to install django-debug-toolbar which your project requires.
Running pip install django-debug-toolbar should fix that import error.
Ideally projects come with a Requirements.txt file that contains the output of pip freeze. If you have one, you can install all of the requirements by running pip install -r Requirements.txt

I tried installing django-heroku via pip so I can deploy my project on heroku but during installation of django-heroku it tried to install psycopg2 along only to produce an error:
Error:pg_config executable not found.
pg_config is required to build psycopg2 from source.please add the directory containing pg_config to the $PATH or specify the full executable path with the option:
python setup.py build_ext--pg-config/path/to/pg_config build...
or with the pg_config option in 'setup.cfg'.
And I also wish to know if I'm required to pip install it since heroku installs the libaries specified in the requirements.txt file,if not required are there changes I need to make to my project before deployment.
Perhaps not optimal solution but it did work for me.
pip install --no-dependencies django-heroku
Be sure to have other required packages installed.
pip install django
pip install whitenoise
pip install psycopg2-binary
P.S. I have already had postgresql installed on my Mac. Not sure why I was getting the same error.
I renamed "psycopg2" in the python site packages folder to "psycopg2-binary", and this fixed my issue.
I've installed flask, flask_login, and ldap in the virtualenv for my flask package (to authenticate ldap users with the usernames & passwords of the other users at my company).
When I run my flask app, I get "AttributeError: 'module' object has no attribute 'initialize'"
I'm tried "pip install python-ldap"
but I get a red error (sandwiched between other white text) that reads:
"Failed building wheel for python-ldap"
I have thoroughly examined these:
How to install python-ldap on a python 2.7 virtualenv on windows without compiling
Installing python-ldap in a virtualenv on Windows
https://www.python-ldap.org/docs.html
https://www.linuxjournal.com/article/6988?page=0,1
to no avail.
I've had this error for days now...
(also:
pip install openldap
gives:
Collecting openldap
Could not find a version that satisfies the requirement openldap (from versions: )
No matching distribution found for openldap
...(in and outside of my venv) if that information helps)
I had this error last week and after switching work computers, I recreated the virtualenv and installed all of the other packages and dependencies successfully.
my requirements.txt file contains these lines after a line of git stuff:
click==6.7
Flask==0.12.2
Flask-Login==0.4.0
itsdangerous==0.24
Jinja2==2.9.6
ldap==1.0.2
ldap3==2.2.4
MarkupSafe==1.0
pyasn1==0.2.3
Werkzeug==0.12.2
Has anyone successfully installed python-ldap into a flask virtualenv with windows? If so... how?!
Go to:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#python-ldap
download python_ldap-2.4.38-cp27-cp27m-win_amd64.whl in the same directory that your venv folder is listed under
(ex.)
/myrepo
/myapp
/myapp
/venv
/run.py
/python_ldap-2.4.38-cp27-cp27m-win_amd64.whl
install the .whl file while inside of your venv
venv\Scripts\activate
pip install python_ldap-2.4.38-cp27-cp27m-win_amd64.whl
Voila!
The error
ERROR: Failed building wheel for python-ldap
can occur for several reasons. You actually have to look at what happened above this line. In my case, I just had to install missing dependencies to build python-ldap. You can look them up here. For CentOS 8, I had to install:
sudo dnf install openldap-devel python3-devel gcc
to make
python3 -m pip install --user python-ldap -U
work.
I did pip install django-tinymce and it gives this warning

What does this error means
I have have also installed Grappelli and its documentation says TinyMCE comes with it by default.
So, was pip install django-tinymce unnecessary on my part
The Grappelli documentation doesn't give proper explanation to use it. Can someone gives proper steps to configure tinyMCE
Also when I did python manage.py schemamigration --auto added_tinymce
I got this error
TypeError: __init__() got an unexpected keyword argument 'widget'
so can someone please guide me through it
When I try to install django I keep getting this warning. I tried the solution mentioned in this question but still its the same what should I do ?
My virtual os is ubuntu in vagrant.

These warnings are not a problem; Django is still being successfully installed. (The previous question you mention is asking something quite different, and is not concerned with the warnings.)
I'm trying to install Django 1.4.3, but when I execute pip install, pip keeps installing Django 1.5 version instead 1.4.3
sudo pip install -I Django==1.4.3
It returns:

but if I execute pip freeze, it keeps showing

What am I doing wrong?
Thank you
This could/should/can be helped by clearing the build dir for Django in pip.
There is a bug for this, since version 1.1 see here for details
You can start checking for these folders here if you're on OS X or unix like systems:
~/.pip
/tmp/pip-build-root (or pip-build-$USER, if you aren't running pip as root).
This is if you haven't specified a new build folder when you installed the first version of Django.
Good luck!
As limelight says, you should empty your cache and build directories, or pass in a temporary clean location with the --download-cache and flag.
$ pip help install
[...]
--download-cache <dir> Cache downloaded packages in <dir>.
-b, --build <dir> Directory to unpack packages into and build in. The default in a virtualenv is "<venv path>/build". The default for global installs is
"<OS temp dir>/pip-build-<username>".
I'd like to warn any readers to not use sudo pip install to install Django. It installs Django system-wide. And changing the system-wide version could break system-packages that depend on it. For instance, Ubuntu MAAS and Cobbler depend on the system django package. These are typically services you don't want to break.
If you need a different version than the system-package, use virtualenv to isolate your dependencies from the system.
OP seems to be on OSX and I don't know of any server-wide Mac Django, but that may change. Consider installing python packages with sudo at par to changing the system-installed python with python 3; it might work for now, but have some paracetamol in stock, as you're in for some headaches.
Check your local cache and remove it can be help. I hava installed pymongo==2.5.2. To install pymongo==2.4.1, I remove the cache in /tmp/pip-build-root/pymongo.Then I install pymongo 2.4.1 successfully.
