brew update 更新错误 shallow clone

问题
在 mac 下执行 brew update 时，报如下错误：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
Error: homebrew-core is a shallow clone. homebrew-cask is a shallow clone. To `brew update`, first run: git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask fetch --unshallow These commands may take a few minutes to run due to the large size of the repositories. This restriction has been made on GitHub's request because updating shallow clones is an extremely expensive operation due to the tree layout and traffic of Homebrew/homebrew-core and Homebrew/homebrew-cask. We don't do this for you automatically to avoid repeatedly performing an expensive unshallow operation in CI systems (which should instead be fixed to not use shallow clones). Sorry for the inconvenience! |
解决
解决时本来很简单，只需按上述提示执行相应命令即可：
|
1 2 |
git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask fetch --unshallow |
但是默认关联 git 仓库是国外的，速度慢，还经常被墙，导致 early EOF 之类的错误：
|
1 2 3 4 5 6 7 |
git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow remote: Enumerating objects: 365476, done. remote: Counting objects: 100% (365455/365455), done. remote: Compressing objects: 100% (147319/147319), done. fatal: The remote end hung up unexpectedly12 MiB | 9.00 KiB/s fatal: early EOF fatal: index-pack failed |
换源
国外常用仓库慢的经典解决办法，自然是临时将该仓库临时源设置为国内的镜像。一般使用中科大的：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
<em>## 更新 homebrew-cask</em> cd "$(brew --repo)"/Library/Taps/homebrew/homebrew-cask <em># 更换源</em> git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-cask.git <em># 更新，由于已经 cd 到相应文件夹了，因此不需要通过 -C 指定路径了</em> git fetch --unshallow <em>## 更新 homebrew-core</em> cd "$(brew --repo)"/Library/Taps/homebrew/homebrew-core <em># 更换源</em> git remote set-url origin https://mirrors.ustc.edu.cn/homebrew-core.git <em># 更新</em> git fetch --unshallow |
如果有问题，可以通过如下命令查看远端 repo 是不是设置错了。
|
1 |
git remote -v |
如果错了，可以重新设置远端，然后强制更新：
|
1 2 3 |
git fetch --all git reset --hard origin/master git pull |
最后 brew update 即可。

然后，如果你中途中断过或超时，执行brew update可能会出现：
|
1 2 |
Error: Another active Homebrew update process is already in progress. Please wait for it to finish or terminate it to continue. |
解决方法是去掉锁
|
1 |
rm -rf /usr/local/var/homebrew/locks |
