Go插件工具安装问题
Go插件工具安装问题
在Mac上在学习使用Go或者安装其他带有Go依赖的安装包时（比如git-lfs）可能会遇到Go插件工具安装问题
下面我们就来解决一下这个问题（网上也有相关使用代理的情况，这里不再说明）
引发原因
mac 下的包管理工具brew 可以方便的安装工具包或者相应的软件应用，当使用brew 安装git-lfs（git上传大文件的工具）时，因为依赖Go 语言工具，所以在安装时会报错。下面就brew install git-lfs 时的问题来给出解决方案。
过程思路
如果想直接解决可以直接跳转到解决方案
在网上搜索时发现 https://github.com/golang/tools 是 https://go.googlesource.com/tools.git 的一个镜像。这样我们只要修改brew下载git-lfs的脚本，将 https://go.googlesource.com/tools.git 替换成 https://github.com/golang/tools 应该就可以解决我们的问题。
登录 Homebrew 的官网，找到Packages，
点击 formulae.brew.sh ，选择 Browse all macOS formulae
在搜索框搜索git-lfs，在页面找到Formula code ，查看git-lfs在GitHub上的脚本源码。

end
当前代码中并没有相关 https://go.googlesource.com/tools.git 的信息，因为当前是Go的tools，所以再去查看Go的安装脚本（git-lfs的脚本中依赖Go和Ruby，所以只有可能是这两个里面有问题，因为tools是Go相关的的工具，所以首先我们可以查看Go的安装脚本）。这是Go语言brew的安装脚本 https://github.com/Homebrew/homebrew-core/blob/master/Formula/go.rb

安装脚本里面有请求 https://go.googlesource.com/tools.git 地址的信息，我们可以将这块的替换掉应该就可以。
解决方案
brew在本地管理安装包的文件夹为
/usr/local/Cellar/
brew在本地管理安装脚本的文件夹为
/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula
这里我们只需要修改/usr/local/Homebrew/Library/Taps下Go的安装脚本，将 https://go.googlesource.com/tools.git 替换成 https://github.com/golang/tools 即可。
