    $/usr/bin/ruby ​​-e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
      -bash: curl: command not found

      

    $brew install curl
      -bash: brew: command not found

      

    $xcode-select --install
      -bash: xcode-select: command not found

    In other words, any command executed in the terminal will result incommand not found.

    /usr/bin/xcode-select --install


    Or

    /usr/bin/ruby ​​-e "$(/ usr/bin/curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"


    What happens when the command is executed with the full path specified?

    If you can execute with full path without any problems, it seems that PATH has not been set, so in.bash_profileand.bashrcCheck how your PATH is set.
