m1芯片的mac，按照安装顺序安装homedrew后，无法找到brew，所以无法执行brew update等后续操作

和 M1 无关，Homebrew 早就支持 Apple Silicon，我最新的电脑也是 M1 的。

你的 Homebrew 装在 /opt 下了，需要你自己把 /opt/homebrew/bin 加到系统的 PATH 环境变量中。

我不知道是不是现在缺省装在 /opt 下了，以前是装在 /usr/local 下，就不需要首攻设置了。

谢谢Neo～ 我这几天断断续续的在“蒙圈”的状态下（我记得是有出现'/pot‘的目录），看着应该是完成了环境设置。现在刚安装完jupyterlab。但是出现一串warning（更懵了，刚开始学，完全不明就里）如下： WARNING: The scripts jupyter, jupyter-migrate and jupyter-troubleshoot are installed in '/Users/fayelee/Library/Python/3.8/bin' which is not on PATH.

然后也没有google到一个靠谱的答案（环境设置是在lyric的提示下，边google边瞎猫碰上死耗子完成，我自己这么觉得）
