Homebrew 慢，每次 search 都要联网，install 也要先更新

闲聊灌水

搜索个包名要等好久，加 -d 提示要连个网，好像没法关闭。类似的每次 install 都要先更新，也很慢。

Nice！还是要看手册啊。还有这个选项应该就能搜索不联网

HOMEBREW_NO_GITHUB_API

If set, do not use the GitHub API, e.g. for searches or fetching relevant issues after a failed install.

但是不联网了，这个命令还是很慢，从 6s 变成 5s

听说 Apple 新的 M1 芯片有个什么安全模块开机就得联网 :sweat:

本地搜索没结果的时候才需要用到 GITHUB API 吧。本地有结果关不关应该没区别。

8

这个问题也是一直困扰着我，加了代理好很多。真的很想换成Nix，但又怕nix 软件不够多。有人在mac 上只用Nix的吗？

貌似不是，一上来就连 github api，有没有匹配都是。

现在是这样了？我已经6个月没更新。
