pyenv virtualenv installs outdated version of pip

[ghost]

On my machine, pyenv virtualenv always installs pip in version 19.2.3, which is too old for my purposes.

martin ~ » pyenv virtualenv 3.8.3 test

martin ~ » PYENV_VERSION=test pip --version
pip 19.2.3 from /home/martin/.pyenv/versions/3.8.3/envs/test/lib/python3.8/site-packages/pip (python 3.8)

I don't understand where this pip version comes from. Both system and the base version 3.8.3 have newer versions of pip installed:

martin ~ » python --version
Python 3.9.6
martin ~ » pip --version                                                         
pip 20.3.4 from /usr/lib/python3.9/site-packages/pip (python 3.9)
martin ~ » PYENV_VERSION=system pip --version  
pip 20.3.4 from /usr/lib/python3.9/site-packages/pip (python 3.9)
martin ~ » PYENV_VERSION=3.8.3 pip --version
pip 21.1.3 from /home/martin/.pyenv/versions/3.8.3/lib/python3.8/site-packages/pip (python 3.8)

Is there some configuration or a cache that I am missing? Note that I cannot use PIP_VERSION to specify a newer version, see #381.

What version of pip is pyenv-virtualenv supposed to install?

This may be related to pyenv/pyenv#1980 -- Virtualenv doesn't correctly determine when Pyenv-provided version is switched and provides a wrong cached result.

Try setting the VIRTUALENV_SEEDER envvar to pip -- this will hopefully bypass the broken caching logic.

I have just installed pyenv-virtualenvwrapper with Homebrew and am also running into this issue (in particular; I have pip==22.3 but when I do mkvirtualenv, I get pip==22.2.3).

The solution doesn't seem to do the trick:

~/Movies 
❯ pip --version
pip 22.3 from /Users/dteiml/.pyenv/versions/3.8.12/lib/python3.8/site-packages/pip (python 3.8)

~/Movies 
❯ export VIRTUALENV_SEEDER=pip

Is there any currently working solution to this? Why was this issue closed? @native-api

Okay, looking more closely:

martin ~ » pyenv virtualenv 3.8.3 test
Looking in links: /tmp/tmpl49cyvq9
Requirement already satisfied: setuptools in /home/martin/.pyenv/versions/3.8.3/envs/test/lib/python3.8/site-packages (41.2.0)

@MartinAltmayerTNG Seems that this Pip is taken from the base installation. So upgrade the Pip there.
Or the environment already exists and pyenv virtualenv 3.8.3 test becomes a no-op.

❯ mkvirtualenv test
created virtual environment CPython3.8.12.final.0-64 in 1956ms

@hacker-DOM Since mkvirtualenv comes from Homebrew, it probably uses Homebrew's Python as base rather than Pyenv-provided Python, and takes Pip from there. So this problem is not Pyenv-related.

I have the same issue.
I tried to set the PIP_VERSION but ran into the "colorize command not found problem".
Then I set GET_PIP_URL=https://bootstrap.pypa.io/get-pip.py but this didn't help either.
Also tried export VIRTUALENV_SEEDER=pip as you mentioned.

It's always installing an older pip version despite having:

pip 22.3.1 from /Users/heinzi/.pyenv/versions/3.9.0/lib/python3.9/site-packages/pip (python 3.9)

Any other ideas @native-api and thanks for your work!

@moneymanolis Please export PYENV_DEBUG=1, run the faulty command to demonstrate the issue and attach the resulting debug trace as a gist.

[moneymanolis]

Will do!
