当我尝试在终端中执行 ls 时，它说找不到命令。
在我破坏一切之前， echo $PATH 的输出是这样的：
/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/gabrijelagavric/.gem/ruby/2.6.5/bin:/Users/gabrijelagavric/.rubies/ruby-2.6.5/lib/ruby/gems/2.6.0/bin:/Users/gabrijelagavric/.rubies/ruby-2.6.5/bin:
我试图跟随一些线程，但我似乎不明白我具体需要运行什么来更改我的 .zshrc 文件（该线程说要更改 .zshrc 中的 PATH 变量：在 zsh 上找不到命令）
所以，我将其粘贴到终端中：
echo "export PATH=/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/gabrijelagavric/.gem/ruby/2.6.5/bin:/Users/gabrijelagavric/.rubies/ruby-2.6.5/lib/ruby/gems/2.6.0/bin:/Users/gabrijelagavric/.rubies/ruby-2.6.5/bin:" >> ~/.zshrc
进而source ~/.zshrc"
但后来我得到了这个回应

detect-clipboard:33: command not found: uname
