Hello, I'm confused about using Python virtual environments in the GNU system. I used to do the following on Debian to create a virtual environment for writing documentation in Sphinx:
#+BEGIN_EXAMPLE $ python3 -m venv ~/.virtualenvs/ezfinge $ source ~/.virtualenvs/ezfinge/bin/activate (ezfinge) $ pip install Sphinx [...] You are using pip version 18.1, however version 19.1.1 is available. You should consider upgrading via the 'pip install --upgrade pip' command. #+END_EXAMPLE After this, I can create Sphinx-based documentation and build it normally. However, when I try to upgrade pip following the recommendation above, I get the following message: #+BEGIN_EXAMPLE (ezfinge) $ pip install --upgrade pip Collecting pip Using cached https://files.pythonhosted.org/packages/5c/e0/be401c003291b56efc55aeba6a80ab790d3d4cece2778288d65323009420/pip-19.1.1-py2.py3-none-any.whl Installing collected packages: pip Found existing installation: pip 18.1 Not uninstalling pip at /gnu/store/x67xvqx6jmgln1dxyvhvc7k9grbcdvy6-profile/lib/python3.7/site-packages, outside environment /home/sirgazil/.virtualenvs/ezfinge Can't uninstall 'pip'. No files were found to uninstall. Successfully installed pip-19.1.1 You are using pip version 18.1, however version 19.1.1 is available. You should consider upgrading via the 'pip install --upgrade pip' command. #+END_EXAMPLE >From my Debian experience, I would expect pip to be upgraded and the message >at the end would disappear. I get this information about the pip in the Python >environment: #+BEGIN_EXAMPLE (ezfinge) $ which pip /home/sirgazil/.virtualenvs/ezfinge/bin/pip (ezfinge) $ pip --version pip 10.0.1 from /home/sirgazil/.guix-profile/lib/python3.7/site-packages/pip (python 3.7) #+END_EXAMPLE I don't understand why the pip 19.1.1 is not seen. I also don't understand where the pip 10.0.1 comes from (the pip 18.1 is the one installed in my user profile). I'm using this Guix: #+BEGIN_EXAMPLE $ LANG=C guix describe Generation 3 Jun 15 2019 09:49:31 (current) guix ddd401d repository URL: https://git.savannah.gnu.org/git/guix.git branch: master commit: ddd401d28fb09f1f8ce96f2fc24226887a812412 #+END_EXAMPLE Thanks, --- https://sirgazil.bitbucket.io/
