Running windows with python 2.7, setuptools, pip and wheel at latest release. Trying to install dependencies using
pip install -r requirements.txt
failing because "one or more wheels failed to build".
Log:

Failed to build MarkupSafe SQLAlchemy pycrypto
(Removed complete output because over character limit but all reach a certain point then say some file is not found)
However according to http://pythonwheels.com/ there are no wheels for those packages so why is pip trying to build wheels for them?
Try using python -m easy_install SQLAlchemy instead.

I'm trying to run the package, pip install psycopg2==2.7.* ,on my PyCharm terminal so I can deploy my site but I get the message that appears below

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'.
If you prefer to avoid building psycopg2 from source, please install the PyPI
'psycopg2-binary' package instead.
For further information please check the 'doc/src/install.rst' file (also at
<https://www.psycopg.org/docs/install.html>).

ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.
WARNING: You are using pip version 19.2.3, however version 20.2.2 is available.
You should consider upgrading via the '`pip install --upgrade pip`' command.
If you are on Linux, you will need to install PostgreSQL to run your database and then to connect the clients to your PostgreSQL database you will need other packages like libpq-dev, libpq5.
You can install the above packages with the below commands.
sudo apt-get install postgresql
sudo apt-get install libpq5
sudo apt-get install libpq-dev
So if you’re on Mac, I can think of two ways:
pip install psycopg2-binary
Install PostgreSQL with brew or the excellent postgre.app and point the path to pg_config binary (this is actually the error you’re getting)
On Mac I did brew install postgresql and it did the trick for me
I am trying to visualize the database diagram in django.
in Docker file I have:
RUN apt-get install -y python3-dev graphviz libgraphviz-dev
RUN apt-get install -y python-pygraphviz pkg-config
and in requirements.txt I have:
django, psycopg2, djangorestframework, PyJWT, gunicorn, channels, django-extensions, graphviz, cGraph, pygraphviz
but I get this error :
Building wheel for pygraphviz (setup.py): started

Failed to build pygraphviz ... ERROR: Service 'web' failed to build: The command '/bin/sh -c pip install -r requirements.txt' returned a non-zero code: 1
any idea about this error?
I think you have the wrong Package, try it with
docker-compose <-f local.yml> run --rm <containername> pip install graphviz
Or add it to your requirements:
graphviz==0.16 or 0.1*
Also change your Dockerfile RUN to:
RUN pip install -r /requirements/local.txt
dont call every single library.
Little late but hope that helps, Cheers.
I needed to upgrade PostgreSQL from version 9.5 to version 11. After that, when I recreated my virtualEnv from a 'requirements.txt' file, I started giving the following error when installing the psycopg2 package:
Collecting psycopg2 == 2.6.2 (from -r conf/requirements.txt (line 50))

Error: could not determine PostgreSQL version from '11 .1 '
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-0Q7bhV/psycopg2/
After some research, I ran the following commands to try to solve, but it did not work:
sudo apt-get install postgresql-server-dev-all
sudo apt-get install postgresql-common
Finally, I noticed that version 2.6.2 of psycopg2 only supports version 9.5 of postgresql. For 11 you should use the latest version of psycopg2, that is, version 2.7.7. After you change the requirements.txt file, and the virtualEnv has been recreated correctly.
I hope it will be useful to others.
Go for this Command Python3 - sudo apt install libpq-dev python3-dev

I have some old Django projects that I'm moving to a new server, these were written for Python2.6, Django1.4.3
I've installed python2.7, created the virtualenvs in my home directory, adjusted paths and references to the Python version.
I created a virtualenv for Python2.7:
virtualenv -p python2.7 ~/.virtualenvs/my_site/
When I activate the virtualenv and then cd into the web site directory and run
pip install -r requirements.txt
after successfully fetching all the libs, the following error is displayed for every line in requirements.txt:

error: invalid command 'bdist_wheel'
I've found many other similar questions on stackexchange and other sites, and tried the fixes but no luck!
Why can I not create a wheel in python?
Why is python setup.py saying invalid command 'bdist_wheel' on Travis CI?
Can't build wheel - error: invalid command 'bdist_wheel'
I have pip 10.0.1
wheel IS installed (through pip install wheel), I've also run the following in my virtual env:
pip install --upgrade pip ('Requirement already up-to-date')
pip install setuptools --upgrade ('Requirement already up-to-date')
python setup.py bdist_wheel ('error: invalid command 'bdist_wheel'')
What else can I look at to fix this?
Not sure why, but uninstalling wheel fixed it
I uninstalled wheel with a view to reinstalling it, but it worked without reinstalling.
pip uninstall wheel
I've got two Heroku apps, running on the same codebase. The 1st is used as staging env and it works as expected (it auto deploys the devel branch) and the 2nd is used as the production app (auto deploying the master branch).
Today I did a minor code-level change and submitted a PR from devel to master and merged it. From that moment, heroku cannot deploy my master branch in production.

ImportError: No module named site

Well, as fas as I know, there's no "site" module/app or anything in my code, so I cannot understand what's the problem in this case. I remind you, the devel branch auto deploys as expected in the respective Heroku app.
Any ideas?
