Homebrew更新源

引用:brew update 慢 解决办法 镜像更新源

Brew 是OS X 上类似apt-get以及yum的一个软件包管理器,它依托于Github………………

所以,虽然你侥幸下载到了 brew,但你肯定是无法更新 brew 的。原因你懂。不过虽然不能更新 brew,但这只是指brew这个管理器本身罢了,软件还是可以安装的。但由于无法使用 brew update 也就无法更新软件……我们有必要来给 brew 换源。

更新

注意,如果你按照让 Homebrew 用更新这篇文章来操作了,那你就没有必要切换镜像源,因为已经全局代理了,否则的话会导致brew无法更新——因为国外也不能轻易访问国内的。
如果你两者都做了,那么就需要使用下面的命令重新安装 brew :

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"
 
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

brew 的镜像源

brew 也有镜像源?嗯,确实有的,而且还不止一个:

  • 中科大brew镜像源
  • 清华brew镜像源

更换镜像源

cd /usr/local
git remote set-url origin git://mirrors.tuna.tsinghua.edu.cn/homebrew.git
//清华镜像源
git remote set-url origin http://mirrors.ustc.edu.cn/homebrew.git
//中科大镜像源
//二者选其一即可更新

后续操作

cd ~
mkdir tmp
cd tmp
//以下要与你选择的镜像源相同
git clone git://mirrors.tuna.tsinghua.edu.cn/homebrew.git
git clone http://mirrors.ustc.edu.cn/homebrew.git
 
sudo rm -rf /usr/local/.git
sudo rm -rf /usr/local/Library
sudo cp -R homebrew/.git /usr/local/
sudo cp -R homebrew/Library /usr/local/

排错

如果你遇到如下问题:

$: brew update
Stashing your changes:
 M .gitignore
 M .yardopts
 M README.md
 M share/doc/homebrew/Acceptable-Formulae.md
 M share/doc/homebrew/Common-Issues.md
 M share/doc/homebrew/FAQ.md
 M share/doc/homebrew/Formula-Cookbook.md
 M share/doc/homebrew/Homebrew-0.9.3.md

 M share/man/man1/brew.1
fatal: Unable to create '/usr/local/.git/index.lock': Permission denied
Cannot save the current index state
Error: Failure while executing: git stash save --include-untracked --quiet

那么就安照如下命令排错:

sudo chgrp -R admin /usr/local
//确保目录归属管理组
sudo chmod -R g+w /usr/local
//确保管理组可读

最后

没了,运行 brew update 来愉快地更新吧!然后 brew upgrade 。
