# conda run is broken. It does not remove the shell-script-added base-env PATH entries from the
# front of PATH, so when it adds the new env, if there was *another* env activated, then that is
# the one that gets replaced with the PREFIX env PATH entries. Software from the base-env gets
# run instead. This happens on all OSes and this test-code cannot be enabled until conda run is
# free of this problem.
