I am having trouble installing a plugin I am developing. It works on one system I am using at work and fails on my system at home. The home system has the latest daily build on it. The work system has an earlier daily build on it. This is what I try to do inside chimerax: devel install ~/dev/bphon/chimerax-plugin/tut_tool_qt And this is the installation error: open /usr/lib/ucsf-chimerax-daily/lib/python3.9/site-packages/pip/__pip-runner__.pyTraceback (most recent call last): File "/usr/lib/ucsf-chimerax-daily/lib/python3.9/site-packages/pip/__pip-runner__.py", line 49, in <module> assert __name__ == "__main__", "Cannot run __pip-runner__.py as a non-main module" AssertionError: Cannot run __pip-runner__.py as a non-main module Error opening python file /usr/lib/ucsf-chimerax-daily/lib/python3.9/site-packages/pip/__pip-runner__.py Any idea what is happening? I may have run into this problem some time ago on the work computer and fixed it but I honestly don't know. Please forward this to the bugs email list of it should go there instead. Thanks. Sorry for yet another question. You guy seems very busy with mail recently.
