I kept getting this error when installing pow on macOS. There are some old threads about it, with fixes for previous verisons of OSX prior to El Capitan, but for the most part it seems to be a solved bug.

If you're getting this error too, perhaps the solution will be similar to mine?
It turned out that I had at some point changed the default shell of my root user to
/usr/local/bin/fish, then uninstalled fish, and never bothered to set it back. I guess this isn't really a problem most of the time because not much should (hopefully) ever run as root, but it finally surfaced here when trying to install Pow.
My solution was the following:
- Enable the root user with
- If you try to
sudo su, you will get something like
su: /usr/local/bin/fish: No such file or directory
- Change root's shell with
sudo chsh -s /bin/sh
- Disable the root user with
