Cannot properly uninstall virtualenv about pyenv-virtualenv

[yyuu]

Have you try the shell version (pyenv shell)? Something might be remaining your environment variable of PYENV_VERSION.

[matthieugrieger]

No, I haven't. I will make sure to try that when I get home.

[matthieugrieger]

Finally got around to testing it out again. The problem seems to have fixed itself somehow.

Thanks anyway!

I have the same issue on OS X after rm -rf ~/.pyenv/versions/{my-env-name}.

@j-bennet
See a64f194 - there might be dirs installed.

Are you using the latest pyenv-virtualenv?
Can you provide a test case / steps to reproduce it?
Is the env used somewhere as a local or shell version?

The ~/.pyenv/versions/{my-env-name} typically nowadays will be a symlink only to the real version.

[j-bennet]

Latest. The env was used as local for a dir. I do not have ~/pyenv/versions/{version}/envs directory. Searched for it, but no.

[blueyed]

So what are your symptoms regarding this issue?
What errors do you get and when?

If it happens on shell startup, you could try from an existing shell to run env PYENV_DEBUG=1 $SHELL, which would open a subshell, probably with debug info. Then you can see where the error is coming from (search the output).

If that does not help, try export PYENV_DEBUG=1 in an existing shell and then trigger it.

[blueyed]

Steps to reproduce this would be very useful, because then it could be fixed and added to the test suite.

[blueyed]

I've tried to reproduce it:

% pyenv virtualenv test-foo
% pyenv local test-foo
% rm -rf ~/.pyenv/versions/test-foo

I do not get any errors after that, also for a new shell in this dir, but pyenv version says pyenv: version \test-foo' is not installed ...`, and the same error happens when trying to run any command managed by pyenv.

That's the expected behaviour somehow: pyenv tries to load/use the version you specified, and errors out because it does not exist anymore. There is no way pyenv could or should update all your .python-version files.

If you see this during shell startup it might be cause by using python etc in your startup scripts (likely a bad idea anyway performance-wise).

~/.pyenv/versions/test-foo is not a symlink for me currently however, too.

[blueyed]

Anyway, you can use pyenv version to see where it is coming from.

[blueyed]

In @matthieugrieger it was probably still set in the shell env (PYENV_VERSION), and fixed itself with a new shell (where it was not set to a non-existent version).

[j-bennet]

The symptoms are:

• when I try to execute any pyenv command, or
• when I open a new shell

I see pyenv: {my-deleted-version}' is not installed, and command is not executed (the command was trying to create a new virtualenv; it was not created).

[matthieugrieger]

@blueyed: Yes, I believe that is what happened.

[j-bennet]

It's not set at all. echo $PYENV_VERSION: nothing is printed.

[blueyed]

@j-bennet
In your case it would be a .python-version file.
What does pyenv version give you?

[j-bennet]

Steps to reproduce.

1. mkdir ~/repos/boo
2. cd ~/repos/boo

The following steps are all inside boo.

Umm. It seems I forgot to redirect stderr to /dev/null. Just doing so would stop pyenv-virtualenv to do spamming.

https://github.com/yyuu/pyenv-virtualenv/blob/b9951fa69c13b1dbde0708bd70d8f85d21fd9858/bin/pyenv-sh-activate#L64

[yyuu]

@matthieugrieger @j-bennet I believe that the spamming will be suppressed with 9414a6b. Please give it a try.

[j-bennet]

@yyuu I installed pyenv with homebrew, how do I update it to get the fix?

[yyuu]

@j-bennet Just try upgrading in the standard manner of Homebrew. 'brew update && brew upgrade pyenv pyenv-virtualenv'.

[j-bennet]

Does not seem to help.

In fact, pyenv is even more chatty now:
