英文:
Go: Install package with -u command
问题
我正在尝试通过运行以下命令来安装一个Go包（https://github.com/jteeuwen/go-bindata#installation）：
go get -u github.com/jteeuwen/go-bindata/...
我遇到了这个错误：
package github.com/jteeuwen/go-bindata/...: 无法下载，$GOPATH未设置。有关详细信息，请参阅：go help gopath
我的GOPATH已经按照普通方式设置了。我理解这是由于-u命令引起的...我该如何解决这个问题？
英文:
I'm trying to install a Go package (https://github.com/jteeuwen/go-bindata#installation) by running this command
go get -u github.com/jteeuwen/go-bindata/...
I get this error:
package github.com/jteeuwen/go-bindata/...: cannot download, $GOPATH not set. For more details see: go help gopath
My GOPATH is set in the ordinary way. I understand this is caused by the -u command... how do I resolve this?

这取决于你的操作系统，但请确保在你的.bashrc文件中设置了GOPATH（参考这个问题），或者至少设置为：
export GOPATH=/home/<username>/go
这样，其他进程（如go get）将继承该变量。
在Windows上，你可以在用户环境变量中声明该变量。
要检查已设置的内容（"打印Go环境信息"）：
go env
如果变量已经设置，但仍然无法进行go get -u，那么可能类似于问题42：
你的问题是你已经将Go安装到了一个需要特权升级才能安装的位置。
还要检查你的GOROOT和Go的安装位置。
英文:
It depends on your OS, but make sure your GOPATH is set in your .bashrc (as in this question) or least set with
export GOPATH=/home/<username>/go
That way, other processes (like go get) will inherit that variable.
On Windows, you would declare that variable in your user environment variables.
To check what is already set ("Print Go environment information"):
go env
If the variable is already set, but a go get -u still fails, then this could be similar to issue 42:
> Your issue is that you have installed go to a location that requires privilege escalation to install to.
Check also your GOROOT and where go is installed.
