Something is wrong with my system, because this manifests on bootstrap of 5.2.2 checkout...

[dalthviz]

Just in case, I checked with the Windows installer generated at #17533 and seems like all the dependencies are being shown:

Checking with the latest 5.x d3abf35 I also get all the dependencies:

Maybe something is happening when parsing/computing the dependencies on MacOS?

[mrclary]

Okay, the issue with bootstrap is a non-issue: I was opening the dependencies window before they were computed. If I wait just a little longer or close and reopen the window, the dependencies are there, including spyder-terminal.

However, for the macOS app, the spyder-terminal still does not show up even though it is installed in the application. I'll have to investigate at which commit this manifested to understand what changed.

@dalthviz, I'm hoping that there is something simple like parsing the dependencies, as you suggest.

[mrclary]

The issue is isolated to #16651. Updating py2app has caused spyder-terminal to stop loading. I'll have to investigate.

[mrclary]

It appears that pkg_resources does not locate any entry_points for any packages which have .dist-info files in python39.zip. This could be a problem for more than just spyder-terminal. I don't think this is directly related to py2app; it is a bug/feature of pkg_resources since simply copying the dist-info file to the python3.9 directory after app bundling alleviates the issue.

I'll do some more research...

Closing this issue since the primary problem was not a problem.
