bump2version installed in virtualenv - error

[jonathan-s]

I tried to get bump2version working. The command that I ran was bump2version --help

The traceback that I get is the following.

It looks like the error occurs when bumpversion checks for the presence of git or hg.

These are the commands it calls:

git rev-parse --git-dir
hg root

Could you check if these commands are functional when the virtualenv is activated?

[florisla]

The code checks for errors ENOENT or EACCES, but not for ENOTDIR. Not sure which directory is assumed to be present though.

[jonathan-s]

When running git rev-parse --git-dir I get the output .git. I don't use mercurial. I might add that I get the error even without virtualenv. Ie with or without virtualenv I get the error.

I'm using pyenv if that can be of assistance.

I don't have access to an OS X machine... Could you do the following as a test?

In File /Users/jonathan/projects/foxflash-backend/django-sockpuppet/venv/lib/python3.6/site-packages/bumpversion/vcs.py line 55, replace

            if e.errno in (errno.ENOENT, errno.EACCES):

with

            if e.errno in (errno.ENOENT, errno.EACCES, errno.ENOTDIR): 

And then check if bump2version behaves as it should.

I can confirm that the edit above works.
I had this error on my Mac:

git rev-parse --git-dir returns .git as it should. I don't use mercurial.

Just to confirm that this actually helps.

@florisla @ekohl When is the next release due? This bug's been more than a year old, and fixed more than a year ago. I also didn't see it tagged with the "next release". So it might be a nice idea to do a patch release (bumpversion patch) to help ease the pain for those using Macs ...

[ekohl]

I must admit that I've been really swamped with other work and in practice don't really use bumpversion anymore. Perhaps it's time to evaluate maintainership.
