Pip3 on mac os x 12.5 does not work even with virtual environment activated-CodePudding

I currently cannot successfully use venv to install python packages on my mac via pip3. I am currently running 12.5 Monterey.

Without a venv activated, running which python3 yields

/Library/Frameworks/Python.framework/Versions/3.10/bin/python3

I installed Python3.10.6 from python.org, so this is not the system version of python that ships with osx 12.5. After activating a virtual environment:

$ source ~/py_envs/my_env/bin/activate

I can then run the following commands and get the following output:

$ which python3
/Users/admin/py_envs/my_env/bin/python3
$ which pip3
/Users/admin/py_envs/my_env/bin/pip3

So far, this all seems correct. However when I attempt to install a package via pip3 with the virtual environment activated, I get the following output:

$ pip3 install redis

[notice] A new release of pip available: 22.2.1 -> 22.2.2
[notice] To update, run: pip install --upgrade pip

So it appears the version of global version of python3 is being referenced, even if I've activated my virtual environment. I have tried running pip install --upgrade pip which yields similar results. I have also tried installing python3 via homebrew, but attempting to install pacakges with pip still results in the same error. So far, I have not been able to find a solution on SO or elsewhere. Does anyone have any insight on this issue? Thanks in advance.

CodePudding user response：

try running type pip3 to see if it is aliased. if it is aliased unalias pip3. and try again. if that fails I suggest using pyenv to manage your python versions. remove all versions of python installed via homebrew and use pyenv to install python3. hope this helps.

CodePudding user response：

To upgrade the pre-installed Python3 on macOS to the latest or higher version(s), you can use pyenv, which can be installed using Homebrew:

brew install pyenv
pyenv install [Python version]
You can see the list of the Python versions by running pyenv versions

and finally, to set a version as a default one, just run: pyenv global [Python version]

To set up a path for pyenv in the terminal (in my case => zsh), I manually add the following lines to .zshrc

export PYENV_ROOT="$HOME/.pyenv"

export PATH="$PYENV_ROOT/bin:$PATH"

eval "$(pyenv init --path)"
