I realized we have a lot of “tribal knowledge” about how things can go wrong during installation, but none of it is really written down. I thought making a post and converting it to a community wiki could be a good idea.
conda clean --allthen try again
Post-link script fails with Python traceback
Check that PYTHONPATH isn’t set. conda may be loading the packages used in the post-link script from outside the environment, which will not work.
Post-link script failed for GenomeInfoDB:
The database is downloaded as a post-link step. You likely just hit a network error, simply re-trying the installation should correct the issue (along with moving to a more stable network).
Please add more as you remember/see them!
