Dear Maintainer,
I gave pyenv a try and noticed the following issue.
The pyenv(1) man page states, in part:
[...]
| 1. Append the following to $HOME/.bashrc
|
| if command -v pyenv 1>/dev/null 2>&1;
| eval "$(pyenv init - bash)"
| fi
[...]
However, this suggestion is wrong.
Firstoff, a "then" is missing after the semicolon (syntax error).
Secondly, if the PYENV_ROOT environment variable is not set to
a suitable user-writable directory, the following error is generated
each time a shell is started:
mkdir: cannot create directory ‘/usr/share/pyenv/versions’: Permission denied
A better suggestion seems to be to append the following to $HOME/.bashrc
export PYENV_ROOT="$HOME/.pyenv"
if command -v pyenv 1>/dev/null 2>&1; then
eval "$(pyenv init - bash)"
fi
However, this (after I started actually using pyenv) began to produce
the following error each time a shell is started:
pyenv: cannot rehash: /usr/share/pyenv/shims isn't writable
Other than this (do you need a separate bug report for it?), pyenv
seems to work, even though my $PATH is modified by adding three new
directories:
(a) $HOME/.pyenv/shims
(b) /usr/share/pyenv/shims
(c) /usr/share/pyenv/bin
I can understand the reason behind the addition of directory (a),
which is $(pyenv root)/shims , as documented in the man page.
I am not sure I understand why directory (c) is added, as this
directory does not exist.
I suspect that the addition of directory (b) is the cause of the
error I am seeing.
Please fix the man page and/or the manipulation of the $PATH by pyenv
(and/or forward my bug report upstream, as appropriate).
Thanks for your time and dedication!
We believe that the bug you reported is fixed in the latest version of
pyenv, which is due to be installed in the Debian FTP archive.
A summary of the changes between this version and the previous one is
attached.
Thank you for reporting the bug, which will now be closed. If you

Hello, this bug was ultimately caused by /etc/profile.d/pyenv.sh, which Debian ships. It sets the PYENV_ROOT to a directory that the user cannot actually write to, in the users environment. This basically breaks all of pyenv for non-root usage; installing versions no longer works even if the shims for shell integration aren't used at all, which is what I'm doing. If there's some need for me to add a bit more urgency to getting the fixed version rolled into trixie, I'd say this is it: pyenv is unusable out of the box for anyone but root even without any shims as soon as the user logs back into their shell, because the profile.d file that is in 2.5.4 but thankfully will be removed in 2.5.5 sets environment variables to something that doesn't make sense.
Control: found -1 pyenv/2.5.5-1
[...]
Hello Nicolas,
thanks for spotting this, which really seems to be the root cause of
the "cannot rehash" error.
However, file '/etc/profile.d/pyenv.sh' still seems to be shipped in the
pyenv/2.5.5-1 Debian package.
I am thus reopening this bug report.
Josenilson,
please drop '/etc/profile.d/pyenv.sh' from the Debian package.
Moreover, the man page now suggests:
[...]
| 1. Append the following to $HOME/.bashrc
|
| if command -v pyenv 1>/dev/null 2>&1; then
| export PYENV_ROOT="$HOME/.pyenv"
| export PATH="$PYENV_ROOT/bin:$PATH"
| eval "$(pyenv init - bash)"
| fi
[...]
This suggestion is better than it was in the pyenv/2.5.4-1 Debian
package, but now suggests to add a path that does not seem to
exist ("$PYENV_ROOT/bin").
I would say that a better suggestion would more simply be:
[...]
| 1. Append the following to $HOME/.bashrc
|
| if command -v pyenv 1>/dev/null 2>&1; then
| export PYENV_ROOT="$HOME/.pyenv"
| eval "$(pyenv init - bash)"
| fi
[...]
Please enhance the man page.
Thanks for your time and dedication.
