+- Stop ``deactivate`` in the bash/zsh activation script from aborting under ``set -e`` when ``hash -r`` fails (for
+  example with shell hashing disabled) by appending ``|| true``, matching CPython ``venv`` (gh-149701) and the existing
+  non-deactivate call - by :user:`gaborbernat`. (:issue:`3152`)
