When I run the code on the macro panel, I get the following error. There is no problem with the system python, but the problem occurs with the python in Glyphs. Is it originally a possible error?

I’ll have a look.

What do you like to is it for?

Thank you.

I found out while fixing the error caused by linking firebase that I posted on the forum before.

Fails when I install the Python 3.9 environment via Plugin Manager and try to fe…tch data with `urllib.request.urlopen()`: ```py Traceback (most recent call last): File "<macro panel>", line 3 File "request.py", line 214, in urlopen return opener.open(url, data, timeout) File "request.py", line 517, in open response = self._open(req, data) File "request.py", line 539, in _open return self._call_chain(self.handle_open, 'unknown', File "request.py", line 494, in _call_chain result = func(*args) File "request.py", line 1413, in unknown_open raise URLError('unknown url type: %s' % type) urllib.error.URLError: <urlopen error unknown url type: https> ``` Then I get the following if I run `import ssl` for troubleshoot: ```py Traceback (most recent call last): File "<macro panel>", line 1 File "ssl.py", line 98 import _ssl # if we can't import it, let the error propagate ImportError: dlopen(/Users/tfuji/Library/Application Support/Glyphs 3/Repositories/GlyphsPythonPlugin/Python.framework/Versions/3.9/lib/python3.9/lib-dynload/_ssl.cpython-39-darwin.so, 2): Library not loaded: /Library/Frameworks/Python.framework/Versions/3.9/lib/libssl.1.1.dylib Referenced from: /Users/tfuji/Library/Application Support/Glyphs 3/Repositories/GlyphsPythonPlugin/Python.framework/Versions/3.9/lib/python3.9/lib-dynload/_ssl.cpython-39-darwin.so Reason: image not found ``` Some of the Mach-O executables inside `Python.framework` look for their dependencies inside `/Library/Frameworks/Python.framework/Versions/3.9`, which doesn't exist on my Mac, according to `$ otool -L`: ``` /Users/tfuji/Library/Application Support/Glyphs 3/Repositories/GlyphsPythonPlugin/Python.framework/Versions/3.9/lib/python3.9/lib-dynload/_ssl.cpython-39-darwin.so: /Library/Frameworks/Python.framework/Versions/3.9/lib/libssl.1.1.dylib (compatibility version 1.1.0, current version 1.1.0) /Library/Frameworks/Python.framework/Versions/3.9/lib/libcrypto.1.1.dylib (compatibility version 1.1.0, current version 1.1.0) ``` Manually fixing things around with `otool` and `install_name_tool` and re-signing the framework did solve the dyld issue for me. All the dependencies are already contained in the framework, so the linkage to a file under `/Library/Frameworks` looks accidental. I also needed to tweak a bit to make sure that the CA bundle can be found by default: ```py import ssl import functools import pip._vendor.certifi as certifi ssl._create_default_https_context = functools.partial(ssl.create_default_context, cafile=certifi.where()) from urllib.request import urlopen print(urlopen('https://github.com/schriftgestalt/GlyphsSDK/raw/Glyphs3/README.md').read().decode('utf-8')) ``` It worked. I have almost zero experience on py2app, but I think the py2app-based build script is supposed to do this for us. If we can make the build right, `urlopen()` should just start to work without [making a request via PyObjC](https://forum.glyphsapp.com/t/the-python-module-cant-handle-https-with-urllib-request/19035/5) instead.

I’ve found that I’ve had the same problem before. Here’s how to fix it. Was it fixed then?
It’s hard for me to try because there’s an error when I try that way.
I hope that it will be resolved quickly by looking at that article.

The script doesn’t work any more. But I think I have fixed it. Can you try? (restarting Glyphs (maybe twice) should give you the latest version).

sindpfla98 · May 28, 2024, 5:18am

I’ve only reinstalled the Python module and I’ve seen that it works fine. Thank you so much for the quick update!
