发现/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core目录是空的

然后执行下面的代码，wget终于安装成功了

cd /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core
git clone https://github.com/Homebrew/homebrew-core.git
brew update
brew install wget

wget安装过程遇到几次超时，重试即可

 

/usr/local/Homebrew/Library/Taps/homebrew/目录下有三个目录，如下：

16:12:50 xxx ~ $ ll /usr/local/Homebrew/Library/Taps/homebrew/
total 0
drwxr-xr-x  17 lipengfei  admin  544  7 23 15:53 homebrew-cask
drwxr-xr-x  16 lipengfei  admin  512  7 23 15:51 homebrew-core
drwxr-xr-x  13 lipengfei  admin  416  7 23 15:53 homebrew-services

三个软件在github上都有，https://github.com/Homebrew

16:16:32 xxx /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask $ git remote -v
origin    https://github.com/Homebrew/homebrew-cask (fetch)
origin    https://github.com/Homebrew/homebrew-cask (push)
16:16:57 xxx /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask $ cd ../homebrew-services/
16:17:05 xxx /usr/local/Homebrew/Library/Taps/homebrew/homebrew-services $ git remote -v
origin    https://github.com/Homebrew/homebrew-services (fetch)
origin    https://github.com/Homebrew/homebrew-services (push)
16:17:07 xxx /usr/local/Homebrew/Library/Taps/homebrew/homebrew-services $ cd ../homebrew-core/
16:17:10 xxx /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core $ git remote -v
origin    https://github.com/Homebrew/homebrew-core.git (fetch)
origin    https://github.com/Homebrew/homebrew-core.git (push)

如果有异常删除目录重新下载就行
