| # Attempt to move any conda entries in PATH to the front of it. | |
| # IDEs have their own ideas about how PATH should be managed and | |
| # they do dumb stuff like add /usr/bin to the front of it | |
| # meaning conda takes a submissive role and the wrong stuff | |
| # runs (when other conda prefixes get activated they replace | |
| # the wrongly placed entries with newer wrongly placed entries). | |
| # | |
| # Note, there's still condabin to worry about here, and also should | |
| # we not remove all traces of conda instead of just this fixup? | |
| # Ideally we'd have two modes, 'removed' and 'fixed'. I have seen | |
| # condabin come from an entirely different installation than | |
| # CONDA_PREFIX too in some instances and that really needs fixing. | |
