[Neel Gore]

Neel Gore  added the comment:

Ah in hindsight I see why this was troublesome; the directory name was "Project 
4/5", and zsh was displaying the / with a :. Renaming the directory to "Project 
4_5" fixed the problem. Thanks everyone!

[Dustin Rodrigues]

Dustin Rodrigues  added the comment:

FWIW, it looks like spaces in directory names in macOS seem to be handled okay 
in both bash and zsh when working with venv's activate script. Colons do not 
and there doesn't appear to be a workaround other than not working in a 
directory with a colon in its name when you want to include that directory in 
your PATH.

[Dustin Rodrigues]

Dustin Rodrigues  added the comment:

What's the name of the current directory? Does it end with "Project 4:5"? It 
may be the colon in the directory name is interfering with the PATH parsing so 
that the shell thinks that the first two entries in your path after the venv 
activate are

/Users/neelgore/Documents/UC Irvine/Y1/Q2/ICS 32/Project 4
5/.venv/bin

instead of

"/Users/neelgore/Documents/UC Irvine/Y1/Q2/ICS 32/Project 4:5/.venv/bin"

being the first entry.

Thanks. I’m guessing the space in the path is causing a problem.

[Neel Gore]

Neel Gore  added the comment:

This is Python 3.9.1 from the normal python.org download.

Before venv activation, "echo $PATH" gives:

/Library/Frameworks/Python.framework/Versions/3.9/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Applications/VMware
 Fusion.app/Contents/Public

After activation, "ls -l .venv/bin" gives:

[Ned Deily]

Ned Deily  added the comment:

It could be that the activate is failing for some reason in that directory or 
terminal session.  Try it in a new terminal session after entering "set -x" so 
you can see the expanded commands.

Eric V. Smith  added the comment:

Where did you install Python from?

Before you've activated the virtual env, please run "echo $PATH".

After you've activated the virtual env, can you run "ls -l .venv/bin" and "echo 
$PATH"?

(sorry for double message)
update:

Just created a venv in Desktop and another in a directory in Documents and got 
the correct behavior both times. Seems like the issue is isolated to the 
certain directory?

[Ned Deily]

Ned Deily  added the comment:

Are you sure there wasn't an existing virtual environment at .venv? By default, 
venv does not upgrade an existing environment. Try deleting the .venv directory 
first, assuming there is nothing in the environment you want to save. Otherwise 
you could try debugging the shell steps with the shell command:

set -x

and, if necessary, debugging the python environment with:

python3 -m test.pythoninfo

zsh 5.8 (x86_64-apple-darwin20.0)
and
macOS Big Sur 11.2.1

This was the normal python dot org installation.

I'm also unable to replicate this. Where did you install Python from? Which 
version of zsh are you running?

Please do not post screen captures. It makes it difficult for users with 
accessibility software and it makes it hard for people trying to help you to 
copy and paste exactly what you've tried.

I'm unable to duplicate your problem.

Fresh python 3.9.1 installation on macOS, shell is zsh
