在终端运行命令：brew update【回车】，报错如下：
error: RPC failed; curl 18 transfer closed with outstanding read data remaining
fatal: the remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
Error: Fetching /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core failed!
这是git报错，在终端运行命令：git conf
