brew命令不能正常使用

问题简介：为了修改GitHub代理，导致homebrew不能正常使用。

起因

想尝试一下https://github.com/AUTOMATIC1111/stable-diffusion-webui，但是运行./webui.sh报错了:大概是gfpgan安装不上。

定位到launch.py.227:

gfpgan_package = os.environ.get('GFPGAN_PACKAGE', "git+https://github.com/TencentARC/GFPGAN.git@8d2447a2d918f8eba5a4a01463fd48e45126a379")

然后修改为：

gfpgan_package = os.environ.get('GFPGAN_PACKAGE', "https://github.com/TencentARC/GFPGAN.git")

不行。

在./stable-diffusion-webui和./stable-diffusion-webui/venv/lib/pyhton3/site-packages/都手动git clone https://github.com/TencentARC/GFPGAN.git 还是不行。

遂放弃。

后记：

添加https://ghproxy.com/即可

gfpgan_package = os.environ.get('GFPGAN_PACKAGE', "https://ghproxy.com/https://github.com/TencentARC/GFPGAN.git")

居然是网络问题，看报错根本看不出来！啊 哒哒哒！

中途可能使用了该命令：

git config --global --unset http.proxy

git config --global --unset https.proxy

经过

第二天，就不能正常使用brew相关的命令了。（brew update会涉及到git fetch更新一些仓库的命令）

但最近有在这上面有需求，就不能回避了

下面为我踩坑时常看到的信息:

brew update --verbose

中途把github的代理弄了好几个版本，也改过DNS8.8.8.8+重启。

把brew改成清华镜像也不是很有用。

解决方案

最后的解决方案是：

step1:

没改DNS，brew镜像.

下面为brew config的输出，以供参考

HOMEBREW_VERSION: 4.0.3-32-ga3207a0

step2:

修改github的代理为clash的端口(mixed-port为7890，或socks5:7891)。
最后我的/Users/changqingaas/.gitconfig文件为:

[user]
	name = chang_qing_aas
	email = 1736731090@qq.com
[safe]
	directory = /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core
[core]
	quotepath = false
[filter "lfs"]
	clean = git-lfs clean -- %f
	smudge = git-lfs smudge -- %f
	process = git-lfs filter-process
	required = true
[http]
	version = HTTP/1.1
	proxy = socks5://127.0.0.1:7891
[https]
	proxy = socks5://127.0.0.1:7891
[http "https://github.com"]
	proxy = socks5://127.0.0.1:7891
[https "https://github.com"]
	proxy = socks5://127.0.0.1:7891

具体命令我没保存，如果觉得有用直接vim .gitconfig修改吧。

我还改了.ssh/config:

Host github.com
   HostName github.com
   User git
   #socks5
   ProxyCommand nc -X 5 -x 127.0.0.1:7891 %h %p

在/etc/config添加:

# Github
140.82.114.3 github.com

185.199.110.133 raw.github.com

185.199.110.133 raw.githubusercontent.com

199.232.69.194 github.global.ssl.fastly.net

185.199.108.153 assets-cdn.github.com

185.199.109.153 assets-cdn.github.com

185.199.110.153 assets-cdn.github.com

step3:

我在brew cleanup 遇到”Failed to download https://formulae.brew.sh/api/cask.json “
这个文件不知道为啥下载很慢，以前没这个问题。
使用wget测出需要好几十个小时，才能下完。
猜测是终端不能翻墙的原因。
遂google
在这里看到解决办法：https://github.com/Homebrew/brew/issues/14516
我做了如下:

rm -r "$(brew --cache)/api" # /Users/changqingaas/Library/Caches/Homebrew/api
export HOMEBREW_NO_INSTALL_FROM_API=1

成功了，绕过了这个文件下载很慢的问题。

但是，当我

brew upgrade

发现了下载速度很慢，不知道这和之前改到清华镜像是否有原因。

==> Fetching node@16
==> Downloading https://mirrors.tuna.tsinghua.edu.cn/homebrew-bottles/node%4016-
######################################################################## 100.0%

step4:

到这里事情并没有结束。

wget https://formulae.brew.sh/api/formula.json

速度依然很慢。

但是，基本每条brew指令都需要下载该文件。

实践后，可知：每次运行brew命令前，可以执行

export HOMEBREW_NO_INSTALL_FROM_API=1

执行之后，基本就能使用brew命令了。不过这样只能起到短期效果。

长期解决办法是：把它写进.zshrc or .bash_profile；source一下。

结尾

git命令翻墙和终端翻墙可能仍是问题。
