I don’t think this is true.  Fish seems to fail to find “python”.  The
error disappears in an environment where “python-wrapper” is available.
A fix would involve replacing the call to “python” with the full path to
the “python” executable.

Here’s a patch:

Subject: [PATCH] gnu: fish: Embed full path to Python.

Fixes <https://bugs.gnu.org/25467>.

* gnu/packages/shells.scm (fish)[arguments]: Rename phase "patch-bc" to
"embed-store-paths"; embed full path to Python.
