"python3: No module named folderify" when attempting to invoke legacy 2.4.2

[cdn-content]

I am still on a MacBook running Catalina, and recently updated my homebrew formulae en masse. I probably should have excluded folderify from the update. Anyhow, now I do have the latest version of folderify, but want to revert to using 2.4.2 in order to have OSX-style folders.

I tried following the steps on the homepage, installing legacy folderify through python. It seems to be installed, but throws an error when attempting to run:

Catalinas-MacBook-Pro:~ catalina$ pip3 install folderify
Requirement already satisfied: folderify in /usr/local/lib/python3.11/site-packages (2.4.2)
Catalinas-MacBook-Pro:~ catalina$ python3.11 -m folderify -v --no-trim /Users/catalina/Downloads/Fonts/mask.png /Users/catalina/Downloads/Fonts 
/opt/local/bin/python3.11: No module named folderify
Catalinas-MacBook-Pro:~ catalina$ python3 -m folderify -v --no-trim /Users/catalina/Downloads/Fonts/mask.png /Users/catalina/Downloads/Fonts 
/opt/local/bin/python3: No module named folderify

As a workaround, I tried reinstalling the older version using the steps described in this article, but also get an error.

The website says to try and "manually checkout the git hash of the tap and install the version" but I don't know where to find that hash and enter it into the code snippet provided.

What if the package can not be found?

For some reason, it can still be the case that brew is unable to find your version:

Error: Could not find <packageName> but homebrew/core is a shallow clone!
Try again after running: ...

In this case, one can manually checkout the git hash of the tap and install the version:

# list all local taps
brew tap

go to tap and check out correct hash

cd /usr/local/Homebrew/Library/Taps/ git checkout

prevent brew from checking out different hash

HOMEBREW_NO_AUTO_UPDATE=1 brew install

can list and switch between all versions

brew list --versions brew switch

I get as far as `git checkout` and hit a wall, because I don't know what hash to put in.

If I could avoid this more convoluted method and install 2.4.2 via python as mentioned in the official instructions, that would be ideal. However, the official method does not seem to be working either, as stated above, even though python seems to indicate that it has been installed.

Catalinas-MacBook-Pro:~ catalina$ pip3 install folderify Requirement already satisfied: folderify in /usr/local/lib/python3.11/site-packages (2.4.2) Catalinas-MacBook-Pro:~ catalina$ python3.11 -m folderify -v --no-trim /Users/catalina/Downloads/Fonts/mask.png /Users/catalina/Downloads/Fonts /opt/local/bin/python3.11: No module named folderify Catalinas-MacBook-Pro:~ catalina$ python3 -m folderify -v --no-trim /Users/catalina/Downloads/Fonts/mask.png /Users/catalina/Downloads/Fonts /opt/local/bin/python3: No module named folderify

Is there something else that I need to do, in order to use the legacy version? Why is it that python can't seem to find folderify in order to run it, if it claims that it has been installed?

Hmm, I'm not sure I can be particularly effective in helping you, given that:

• The Python version is completely unsupported at this point.
• I have a healthy amount of fear when it comes to Python internals, especially on macOS.

I'd suggest double-checking that the version of Python that is installing folderify is also the same that's trying to run it:

command -va pip3
command -va python3

For me, the /opt/homebrew/bin/ version is first in my $PATH for each.

This works for me:

pip3 install folderify
python3 -m folderify # Invoke as a module
folderify-v2 # Invoke the executable installed by Python

It worked! I ended up doing a brew uninstall of the newer one, and doing a reinstall of the legacy version through pip3. Calling folderify-v2 instead of just folderify finally does the trick and doesn't leave a Big Sur folder on my Catalina desktop. Much obliged.
