 ~ $ pipx run https://raw.githubusercontent.com/pipxproject/pipx/master/scripts/migrate_pipsi_to_pipx.py
-bash: pipx: command not found

I guess this is some kind of unanticipated interaction with pyenv

This fixed it:

$ pip uninstall pipx
$ pyenv shell 3.7.4
$ pip install pipx

it was the pyenv shell specifically which seemed to be out of sync, before setting that it had installed pipx to one of my other python 3s which was not currently on the PATH

[anentropic]

maybe I'm supposed to install it to the non-pyenv system python3 though?

there are problems with completions as I have it currently

$ source ~/.bashrc
pyenv: register-python-argcomplete: command not found

The `register-python-argcomplete' command exists in these Python versions:
  3.7.4

[frapbod]

I was running into the exact same problem, at least with the command not found issue.

I'd have the command not found after starting the shell but i'd be able to run the eval afterwards and it would work, my problem was that I had the eval "$(register-python-argcomplete pipx)" before I sourced the pyenv completion.

Seeing as how yours still doesn't find the command afterwards I'd look into seeing if you have pyenv completions set up in your ~/.bashrc at all.

[anentropic]

I come here to ask how to get pipx working when you already have pyenv installed... and I find I already asked 6 months ago, with no resolution.

I really want to follow the installation instructions https://pipxproject.github.io/pipx/installation/ rather than have a weird hacked together set up...

But they don't work if you already have pyenv installed.

Firstly:

$ python3 -m pip install --user pipx
pyenv: python3: command not found

$ brew install python

Cool, let's try the next step:

$ pipx completions

The `pipx' command exists in these Python versions:

Ugh.

Let's get rid of this pipx I installed under a pyenv version previously...

[anentropic]

the bash completions need an extra step to work (due to a dependency was previously installed with --user)...

$ source ~/.bashrc
pyenv: register-python-argcomplete: command not found

The `register-python-argcomplete' command exists in these Python versions:
  3.7.4

to fix this we do the same uninstall and reinstall as above:

$ python3 -m pip uninstall argcomplete
  Successfully uninstalled argcomplete-1.10.0

$ python3 -m pip install argcomplete

$ pipx

The current instructions for macOS (which I assume you're using because you're using Homebrew are (from the README.md at https://github.com/pipxproject/pipx):

On macOS:

brew install pipx
pipx ensurepath

I think the key here is that https://pipxproject.github.io/pipx/installation/ does not have the OS-specific installation instructions that README.md does. We need to fix that.

Another thing to note is that when you install using pip install --user pipx the pipx binary is put in a specific directory that depends on which python you are using. This may or may not already be in your PATH if you're using a non-standard python (like one of the pyenv versions.) The pipx ensurepath step only puts the binary directory for your pipx packages in your path. I suppose we could look at ensuring that pipx is in your path also at this step.

I suppose we could look at ensuring that pipx is in your path also at this step.

We ran into this before and updated the instructions, which currently have this

Assuming you have pip installed for python3, run:

python3 -m pip install --user pipx
python3 -m pipx ensurepath

[itsayellow]

That works for the purpose of running pipx ensurepath, but as far as I understand it, that subcommand doesn't actually check if pipx itself is in the user's path.

The way I install pipx while using pyenv:

desired outcome is to have pipx available globally for the user without poisoning pyenv python versions - keep them pristine: install pipx into separate environment aka pipx install pipx

• install pyenv-virtualenv pyenv plugin (i.e. clone it into ${PYENV_ROOT}/plugins)

• create separate virtualenv just for pipx (so regular pyenv's python version stays pristine):

  pyenv virtualenv 3.7.7 pipx

  specifying python version to be used for pipx env.

• install pipx inside new virtualenv

  pyenv activate pipx
  pip install pipx
  pyenv deactivate

  Now, pipx is available in ${PYENV_ROOT}/shims. If you are using pyenv - this directory should already be in your PATH (added by eval "$(pyenv init - )").

• in order to always run pipx from within its virtualenv, not from active pyenv python, add PYENV_VERSION=pipx to pipx command (pyenv virtualenv name used in venv creation step) which we preserve in .bashrc:

  alias pipx='PYENV_VERSION=pipx pipx'
  
  # pipx completion, place after pyenv init
  if command -v pipx 1>/dev/null 2>&1; then
  eval "$(PYENV_VERSION=pipx register-python-argcomplete pipx)"
  fi

  eval "$(PYENV_VERSION=pipx register-python-argcomplete pipx)"
  fi

This worked for me after I tried anentropic's suggestion of uninstalling pipx and then reinstalling it without the --user flag. I am using WSL2, Ubuntu 22.04 Bash shell on a Windows 10.

I was having the issue where even though reinstalling pipx without the --user flag (via python3 -m pip install pipx) would install the pipx binary to /home/bethany/.pyenv directory, it would assume that it didn't need to install its dependencies because they were still available inside the /home/bethany/.local directory. So, I tried manually removing the /home/bethany/.local directory using sudo rm -rf /home/bethany/.local . (Note: I ensured that I only had the recently installed pipx dependencies inside this folder before removing it!)

This still was ineffective because even though the python3 -m pip install pipx command would install pipx and its dependencies inside the /home/bethany/.pyenv directory, when I ran pipx inside my shell it would complain that there was no pipx command found inside of the /home/bethany/.local directory.

However, after following the above instructions everything works just fine! After running:

$ pyenv virtual env pipx 3.13.0
$ pyenv activate pipx
$ pip3 install pipx
Installing collective packages: platformdirs, packaging, argcomplete, click, userpath, pipx
Successfully installed argcomplete-3.5.1, click-8.1.7, packaging-24.1, pipx-1.7.1, platformdirs-4.3.6, userpath-1.9.2
$ pyenv deactivate
$ echo "alias pipx=`PYENV_VERSION=pipx pipx`" >> ~/.bashrc
$ pipx --version
pipx-1.7.1
$ which pipx
pipx is aliased to `PYENV_VERSION=pipx pipx`
pipx is /home/bethany/.pyenv/shims/pipx

Everything is working great! I actually didn't even have to manually install pyenv-virtualenv, I guess with the most recent pyenv I had installed (pyenv-2.4.16) the pyenv-virtualenv plugin is installed automatically along with pyenv.
