如何解决 macOS 中的 zsh: command not found: flutterfire 问题？

我跟着document https://firebase.flutter.dev/docs/overview/#using-the-flutterfire-cli在我的 flutter 应用程序中添加 firebase。 我收到 1 条警告和消息，例如

    Warning: Pub installs executables into $HOME/.pub-cache/bin, which is not on your path.
    You can fix that by adding this to your shell's config file (.bashrc, .bash_profile, etc.):

  export PATH="$PATH":"$HOME/.pub-cache/bin"

Activated flutterfire_cli 0.1.1+2.

之后我用了

flutterfire configure

我收到了这个错误（不是错误）zsh: command not found: flutterfire如何解决这个问题？我这有什么环境错误吗？

设置路径为zsh on Mac:

1. Run vim ~/.zshrc
2. Press i
3. Paste export PATH="$PATH":"$HOME/.pub-cache/bin"
4. Press esc
5. Type :wq!并按enter
6. 重新启动终端

如果成功which flutterfire将工作。
