pyenv issue with missing /bin/libpython.dylib

[martin-martin]

Hello! Thanks a lot for your article 🙌 .

• MacOS 10.15.3 (Catalina)
• Python 3.8.0 (via pyenv)
• pyenv 1.2.16

When attempting to create the standalone Pomodoro app from your repo with python setup.py py2app, I run into the following error:

----- py2app install output snipped off -----

Do you have any idea or experience whether pyenv could be the culprit here, or is it Catalina?

Can you try rebuilding CPython with enabling framework support? By default of CPython (and pyenv), the python executable will be generated as static linked and libpython*.dylib will not be generated.

env PYTHON_CONFIGURE_OPTS="--enable-framework" pyenv install -v 3.8.0

See here: pyenv/pyenv#443 (comment)

[martin-martin]

That worked (with installing 3.8.1, the .0 version maybe had some conflicts in knowing which one to select ¯_(ツ)_/¯

env PYTHON_CONFIGURE_OPTS="--enable-framework" pyenv install -v 3.8.1

However, now I'm running into the same issue I did with my little app:

Did you manage to run yours on Catalina? I assume that the new security measures might have introduced a problem here.

[visini]

My rumps apps all work fine on Catalina. Could be related to macOS gatekeeper. Can you try disabling gatekeeper? sudo spctl --master-disable

Did this work?

[martin-martin]

Hi @visini thanks for your answer. Just tried running the command before starting the app, and it didn't change anything. Also tried to re-build it after disabling the gatekeeper (for good measure), but still the same result.

@martin-martin Please have a look of my solution to an issue, which might be similar to yours: ronaldoussoren/py2app#284

[martin-martin]

@janikarh yes! Your solution did it for me! Thanks so much 🎉

[visini]

Thank you @janikarh !
