Zsh `which rvm` 或 `which gem` 返回函数内容而不是路径 [英] Zsh `which rvm` or `which gem` returns the function contents instead of the path

问题描述

我以前在我的其他机器上从来没有遇到过这个问题，但由于某种原因，每当我输入时在 ZSH 中

I've never had this problem before with my other machines but for some reason in ZSH whenever I type

which gem

或

which rvm

我得到了函数内容:

gem () {
local result
command gem "$@"
result="$?" 
hash -r
return $result
}

而不是它的路径.对于我的生活，我无法弄清楚为什么会发生这种情况.

instead of it's path. For the life of me I can not figure out why this is happening.

如果我切换到 bash，我就不会有这些问题.

If I switch over to bash I do not have these problems.

推荐答案

这是 zsh 的正常行为.内置的 which 等价于 whence -c，它显示了函数的定义.使用 whence，如果您不想要的话，可以使用不包含 -f 或 -c 的选项组合.例如whence -w gem 将显示gem: function.如果您只想搜索外部可执行文件(而不是别名、内置函数、保留字或函数)，请使用 whence -v.

This is normal behavior for zsh. The which built-in is equivalent to whence -c, which shows the definitions of functions. Use whence, possibly with a combination of options that does not include -f or -c, if you don't want this. For example whence -w gem will display gem: function. If you only want to search for external executables (and not aliases, built-ins, reserved words or functions), use whence -v.
