我必须重新加载shell (exec $ shell -l)来加载Fish shell上的所有路径

Question

我将Fish设置为此处引用的登录shell (https://fishshell.com/docs/current/index.html#default-shell)。

然后安装rbenv。

但是我必须重新加载Fish shell来调用rbenv。

看下面很容易理解。

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

我不喜欢每次启动时都输入exec $SHELL -l。有人帮帮我吗?

这是https://github.com/anyenv/anyenv/pull/99 - anyenv的pyenv设置会干扰其他env:

在当前情况下，pyenv init——path也会导致anyenv的问题。当登录到zsh时，初始化过程停止在pyenv，而不可能继续(如rbenv或sbtenv)。

作为一种解决方案，应该可以只运行两次anyenv init -，因为似乎pyenv设置被跳过或第二次成功(这将是当您运行两次fish时修复它的方法!):

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

可简化为

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