| | 476 | There is a known issue with how SpiderMonkey asserts whether python-virtualenv is working correctly. If you have a custom version of Python 3 installed from Homebrew, you may need to uninstall this first, by running: `brew uninstall --ignore-dependencies --force python@3.9`. Beware that if you did not explicitly choose to install this override, it likely came from another Homebrew package and uninstalling it may break that. Note that macOS 10.15+ comes with Python 3.8 by default, which means an override from Homebrew should generally not be necessary any more. |
