Bug 736888 – =dev-python/jedi-0.17.2 with >=dev-python/parso-0.8.0 produces failures(?) - upstream has deferred fixing its compatibility

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description Markus Walter 2020-08-12 15:22:31 UTC]

As stated in [1]. Otherwise failures occur. I discovered this when trying to run the python-language-server (which did not run).

Note that this dependency has changed in the current HEAD revision.

Here is the error that pops up during the attempt:

<pre>

During handling of the above exception, another exception occurred:
