gopath配置

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。
