1605968 - |./mach test python| aborts on macOS 10.15: "zsh: abort ./mach test python"

Status: NEW

(Firefox Build System :: Mach Core, defect, P3)

Description

[Chris Peterson [:cpeterson]]

I am running macOS 10.15.2 and zsh. I can run other tests using mach (such as ./mach test xpcshell), but trying to run ./mach test python or ./mach python-test aborts without running any Python tests:

firefox % ./mach test python
zsh: abort      ./mach test python
firefox % ./mach --verbose test python
zsh: abort      ./mach --verbose test python

I tried stepping through mach with ./mach --debug-command test python in the Python debugger. I've never used the Python debugger before, but it seems to be aborting when trying to install some pip package here:

I see there a Homebrew issue called "pip3 aborts immediately on Catalina Release version" that might be related (though I can run pip3 commands like pip3 list without problems):

I tried several different ways to reproduce this on the latest macOS 10.15 with zsh (including installing the bogus package mentioned in that github issue), but I wasn't able to. Can you post the list of installed packages you have locally?

Here are the Python packages I have installed. Just let me know if you'd like me to uninstall any (or all) of them to debug this issue.

% brew list -1 --versions | grep python
python 3.7.6_1
python@2 2.7.17_1

% pip3 list

I attempted to make my local set of installed packages as close to comment 2, but I wasn't ever able to reproduce this.
