Hi Jonathan,

I saw your comment on GitHub. May be I have to check the consequences of renaming the mount paths on my Mac. Should be the practical solution of the problem.

What about a symlink? ln -s /Volumes/Macintosh\ SR0/ /HD or something similar? I am not a Mac expert; just pondering.

The path is already linked:

(.venv) ➜  ~ pwd
/Users/mklengel
(.venv) ➜  ~ ls -l Development 
lrwxr-xr-x  1 mklengel  staff  49 Jan 15 22:03 Development -> /Volumes/Macintosh SR0/Users/mklengel/Development
(.venv) ➜  ~ cd Development/pygreet 
(.venv) ➜  pygreet pwd
/Users/mklengel/Development/pygreet
(.venv) ➜  pygreet poetry shell
Virtual environment already activated: /Volumes/Macintosh SR0/Users/mklengel/Development/pygreet/.venv
Enter fullscreen mode Exit fullscreen mode

poetry "sees" the path but ignores the symbolic link.

Michael, what do you think of these steps? Are they a decent, at least temporary, workaround?

sudo ln -s '/Volumes/Macintosh SR0/Users' /homeward
cd /homeward/mklengel/Development/pygreet/
rm -rf .venv
poetry config virtualenvs.in-project false
poetry config virtualenvs.path /homeward/mklengel/Development/.poetryvenv
poetry install
Enter fullscreen mode Exit fullscreen mode

You can adapt names, paths, etc to your liking.

In summary, the above creates a symlink to your users directory (call it homeward or home or whatever you like), then, instead of storing the virtual environment in .venv in the project directory, sets it in poetry's global config to be in a directory of your choosing. Remove the existing .venv in the project, reinstall the project, and it should use the new virtual environment without spaces.

What do you think?

Hi Jonathan,

thx for your suggestion. The symbolic path exists already:

➜  pygreet ls -ld $HOME/Development/pygreet
drwxr-xr-x  8 mklengel  staff  256  5 Feb 13:38 /Users/mklengel/Development/pygreet
Enter fullscreen mode Exit fullscreen mode

Create the virtualenv inside the project's root directory leads to:

➜  pygreet head -1 .venv/bin/greet
#!/Volumes/Macintosh SR0/Users/mklengel/Development/pygreet/.venv/bin/python
Enter fullscreen mode Exit fullscreen mode

Using the default virtualenv folder looks much better:

➜  pygreet poetry config virtualenvs.in-project false

➜  pygreet poetry config --list
cache-dir = "/Users/mklengel/Library/Caches/pypoetry"
experimental.new-installer = true
installer.parallel = true
virtualenvs.create = true
virtualenvs.in-project = false
virtualenvs.path = "{cache-dir}/virtualenvs"  # /Users/mklengel/Library/Caches/pypoetry/virtualenvs

➜  pygreet poetry install
Creating virtualenv greet-hlYPq_3g-py3.9 in /Users/mklengel/Library/Caches/pypoetry/virtualenvs

So may be this is the bug in poetry: the shebang line is not the symbolic one if the virtualenv folder is in the project's root directory.

That's well put.
