在Fish Shell中使用anyenv

Question

I tried to using anyenv in Fish Shell but the error occured.

This is my ~./config/fish/config.fish file.

set -x PATH $HOME/.anyenv/bin $PATH
eval (anyenv init -)

What's wrong with this?

Errors which I got:

$# is not supported. In fish, please use 'count $argv'.

Quick fix:

In ~/.config/fish/config.fish , change:

eval (anyenv init -)

to:

eval (anyenv init - fish)

EDIT: or a slightly more bullet-proof approach:

eval (command anyenv init - fish)

( command forces fish to ignore functions)

What's going on?

anyenv init uses the $SHELL environment variable to determine your active shell and returns some commands, to be executed by the shell, in order to finish the initialization of anyenv .

For some reason the $SHELL variable in your environment points to bash and not to fish (you can verify this by running echo $SHELL ).

The most probable reason is that fish is simply not the default shell for your user. You may execute grep $USER /etc/passwd to find out (look at what it says after the last : ). It's possible to change the default shell with chsh , but if you decide to do it, do it with great care. There might be some important settings in your .bashrc or some other programs may depend on a POSIX-compliant shell to work properly.

Another option is that somewhere you have an override of the $SHELL variable, such that it points to bash and not fish . I have this in my byobu / tmux configuration because it helped me avoid some strange behavior.

Luckily, anyenv init lets the user (you) specify the shell manually (ignore $SHELL ), and that should fix your issue with anyenv .
