I have to reload shell (exec $SHELL -l) to load all PATHs on Fish shell-CodePudding

I set Fish as a login shell referenced here(https://fishshell.com/docs/current/index.html#default-shell).

Then installed rbenv.

But I have to reload Fish shell to call rbenv.

Easy to understand to look at below.

yas  ~  ps -f
  UID   PID  PPID   C STIME   TTY           TIME CMD
  501 55722 55721   0  5:09PM ttys001    0:00.02 -fish //set fish as login shell

yas  ~  rbenv // couldn't find rbenv
fish: Unknown command: rbenv

yas  ~  echo $PATH // couldn't find a path to rbenv

yas  ~  ps -f // shell path has changed from  -fish after reloading.

  501 55722 55721   0  5:09PM ttys001    0:00.16 /opt/homebrew/bin/fish -l

Inside ~/.config/fish/config.fish

if status is-interactive
    # Commands to run in interactive sessions can go here
end
eval (/opt/homebrew/bin/brew shellenv)
status --is-interactive; and source (anyenv init -|psub)
set fish_function_path $fish_function_path "/Users/yas/.anyenv/envs/pyenv/versions/3.10.5/lib/python3.10/site-packages/powerline/bindings/fish"
powerline-setup

I don't like to type exec $SHELL -l on every launch. Does anyone help me out with this?

CodePudding user response：

This is https://github.com/anyenv/anyenv/pull/99 - anyenv's pyenv setup interferes with other envs:

In the current situation, pyenv init --path also causes a problem with anyenv. When logging into zsh, the initialization process stops at pyenv and further (such as rbenv, or sbtenv) are impossible.

As a workaround, it should be possible to just run anyenv init - twice, since it seems that the pyenv setup is skipped or succeeds the second time around (this would be what fixes it when you run fish twice!):

status --is-interactive; and source (anyenv init -|psub)
status --is-interactive; and source (anyenv init -|psub)

Which can be simplified to

if status is-interactive
    anyenv init - | source
    anyenv init - | source
end
