go安装总是尝试使用GOROOT，GOPATH没有在go env下列出 [英] go install always attempts to use GOROOT and GOPATH is not listed under go env

问题描述

我对 GOPATH 有一个相当令人沮丧的问题，尽管它被设置在 .profile 中，在调用 go env 时没有出现，并且不会影响 go install 目标位置。

I'm having a quite frustrating problem with the GOPATH, which, despite being set in .profile, is not appearing when invoking go env, and does not appear to be affecting the go install target location.

我试图使用 go install 来安装软件包，并且得到这个错误，这清楚地表明它正在尝试安装在 / usr / lib / go 中，而不是 / home / me / dev / go 。

I'm attempting to use go install to install packages, and am getting this error, which clearly shows that it is attempting to install in /usr/lib/go, rather than the intended directory of /home/me/dev/go.

$ go install github.com/songgao/colorgo
go install github.com/songgao/go.pipeline: mkdir /usr/lib/go/pkg/linux_386/github.com: permission denied

go env 给出以下结果。

$ go env
GOROOT="/usr/lib/go"
GOBIN=""
GOARCH="386"
GOCHAR="8"
GOOS="linux"
GOEXE=""
GOHOSTARCH="386"
GOHOSTOS="linux"
GOTOOLDIR="/usr/lib/go/pkg/tool/linux_386"
GOGCCFLAGS="-g -O2 -fPIC -m32 -pthread"
CGO_ENABLED="1"

但是最确定的是 设置。

But it most certainly is set.

$ echo $GOPATH
/home/me/dev/go

更新： strong>我已经在〜/ .profile 中导出了GOPATH并找到它，但我仍然遇到同样的问题。

Update: I have exported GOPATH in ~/.profile and sourced it, but I'm still having the same problem.

$ export GOPATH=/home/me/dev/go
$ go env
GOROOT="/usr/lib/go"
GOBIN=""
GOARCH="386"
GOCHAR="8"
GOOS="linux"
GOEXE=""
GOHOSTARCH="386"
GOHOSTOS="linux"
GOTOOLDIR="/usr/lib/go/pkg/tool/linux_386"
GOGCCFLAGS="-g -O2 -fPIC -m32 -pthread"
CGO_ENABLED="1"

再次更新：自我升级到go1.1beta2。我不确定是哪里出了问题，因为 GOPATH 似乎设置正确，但现在所有的显然都在工作。

Update again: This problem has ceased since I upgraded to go1.1beta2. I'm not sure what was wrong, because GOPATH appeared to be set correctly, but it's all apparently working now.

推荐答案

GOPATH 和工作区

$ mkdir -p $HOME/dev/go/src
$ mkdir -p $HOME/dev/go/bin

在 $ HOME /中。 profile ：

export GOPATH=$HOME/dev/go:
export PATH=$PATH:$HOME/dev/go/bin

然后重新启动或注销并登录。

Then reboot or log out and log in.

只要您登录，在运行之前，运行：

As soon as you have logged in, before anything else, run:

$ env | grep -i '^GO'
GOPATH=/home/me/dev/go
$ cat $HOME/.profile

你会得到什么输出？
