无法在使用Homebrew安装的OS X上编译导入net/http的程序。

Can't compile program that imports net/http on OS X with homebrew install

问题

我已经在我的OS X 10.10机器上使用Homebrew安装了Go。每次我尝试编译一个导入net/http的示例应用程序时,都会出现以下错误:

load cmd/cgo: package cmd/cgo: no Go source files in /Users/bbaron/google_appengine/goroot/src/cmd/cgo

我已经正确设置了我的GOPATH变量($HOME/go),并且我的目录结构似乎也是正确的:

/Users/bbaron/go/src/github.com/einsteinx2/gamenotifier
/Users/bbaron/go/src/github.com/einsteinx2/gamenotifier/server.go

为什么cgo似乎认为GOPATH是$HOME/google_appengine/goroot?

我之前(大约一年前)使用App Engine进行过一些Go开发,所以肯定有一些残留的垃圾,但我无法弄清楚我需要更改什么才能使其正常工作。

我已经将App Engine SDK安装到$HOME/google_appengine,但我不明白为什么在我没有导入任何App Engine的内容时会影响到任何东西。

有什么想法吗?

编辑:看起来问题出在我的GOROOT上。以下也是go env的输出:

GOROOT="/Users/bbaron/google_appengine/goroot"
GOTOOLDIR="/Users/bbaron/google_appengine/goroot/pkg/tool/darwin_amd64"

但是,即使我导出了正确的GOROOT并使用echo $GOROOT进行检查,go env仍然没有看到正确的GOROOT。

英文:

I've installed go using Homebrew on my OS X 10.10 machine. Every time I try to compile a sample app that imports net/http, I get the following error:

load cmd/cgo: package cmd/cgo: no Go source files in /Users/bbaron/google_appengine/goroot/src/cmd/cgo

I have my GOPATH variable set correctly ($HOME/go) and my directory structure appears to be correct:

/Users/bbaron/go/src/github.com/einsteinx2/gamenotifier
/Users/bbaron/go/src/github.com/einsteinx2/gamenotifier/server.go

Why does cgo seem to thing the GOPATH is $HOME/google_appengine/goroot

I previously (maybe a year ago) did some go development using App Engine, so there must be some left over garbage, but I can't figure out what I need to change to get this working.

I do have the App Engine SDK installed to $HOME/google_appengine but I don't see why that's affecting anything when I'm not importing any App Engine stuff.

Any ideas?

EDIT: It looks like the problem is my GOROOT. The following are also in go env:

GOROOT="/Users/bbaron/google_appengine/goroot"
GOTOOLDIR="/Users/bbaron/google_appengine/goroot/pkg/tool/darwin_amd64"

But even if I export a correct GOROOT and check with echo $GOROOT, go env does not see the correct GOROOT

得分: 0

原来是我的Google App Engine安装在某种程度上破坏了这些环境变量。我删除了我的主目录中的google_appengine文件夹,然后卸载了Homebrew版本的Go,并从官方的OS X软件包重新安装,现在一切都正常工作了。

英文:

It turned out that my google app engine installation was clobbering these environment variables somehow. I deleted the folder google_appengine in my home directory and then uninstalled the Homebrew version of Go and reinstalled from the official OS X package and now it's working fine.
