1. brew install 每次出现更新检测

安装前输入：export HOMEBREW_NO_AUTO_UPDATE=true

2. brew link graphviz 错误

2.1 总结

1. 执行link程序：brew link XXX
2. 失败则执行：brew link --overwrite XXX
3. 对于顽固份子：sudo rm /usr/local/share/man/man1/circo.1 后重新执行brew link XXX

2.2 过程

1. brew install graphviz 提示：

Warning: graphviz 2.44.0 is already installed, it’s just not linked
You can use brew link graphviz to link this version.

2. 按照提示执行 brew link graphviz：

Linking /usr/local/Cellar/graphviz/2.44.0…
Error: Could not symlink share/man/man1/ccomps.1
Target /usr/local/share/man/man1/ccomps.1
already exists. You may want to remove it:
rm ‘/usr/local/share/man/man1/ccomps.1’
To force the link and overwrite all conflicting files:
brew link --overwrite graphviz
To list all files that would be deleted:
brew link --overwrite --dry-run graphviz

3. 说是有文件应存在了，需要删除后重新安装，先list出来到底有多少文件，brew link --overwrite --dry-run graphviz：
   
4. 一页竟然装不下，这要删除到什么时候去，仔细一看提示中有个：brew link --overwrite graphviz，果断执行之：

Linking /usr/local/Cellar/graphviz/2.44.0… 109 symlinks created
