go语言需要配置一个gopath来安放项目，安装完成之后就要设置，完整步骤如下：
$sudo gedit ~/.bashrc
export PATH="$PATH:/home/yangchao/.linuxbrew/Cellar/go/1.6.2/libexec/bin" export PATH="$PATH:$GOPATH/bin" export PATH="$HOME/.linuxbrew/bin:$PATH" export MANPATH="$HOME/.linuxbrew/share/man:$MANPATH" export INFOPATH="$HOME/.linuxbrew/share/info:$INFOPATH" export GOPATH=$HOME
如果只设置 export GOPATH=$HOME 会出现 go env可以看到gopath但是get 代码之后出现 xxx command not found的错误。
