英文:
golang: go install tries /usr/local instead of GOPATH
问题
这是对我上一个问题的一种后续：https://stackoverflow.com/questions/12514037/golang-installing-packages-in-a-local-directory
我将GOPATH设置为$HOME/prog/go/gopath，并且该路径下存在三个目录：
~/prog/go/gopath$ ls
bin pkg src
现在我尝试安装一个用于访问redis数据库的模块，它要求我在源代码目录中运行
go install
但是go install命令给出了以下结果：
~/prog/go/gopath/src/redis (go1)$ go install
go install flag: open /usr/local/go/pkg/darwin_amd64/flag.a: permission denied
~/prog/go/gopath/src/redis (go1)$ echo $GOPATH
<myhomedir>/prog/go/gopath
（其中<myhomedir>是一个有效的路径）
问题1：为什么go install没有考虑到$GOPATH？
问题2：如何说服go install使用$GOPATH？
英文:
This is somewhat a follow-up to my last question: https://stackoverflow.com/questions/12514037/golang-installing-packages-in-a-local-directory
I have GOPATH set to $HOME/prog/go/gopath and this path exists with three directories:
~/prog/go/gopath$ ls
bin pkg src
Now I try to install a module to access the redis database which asks me to run
go install
inside the source directory. But the command go install gives me
~/prog/go/gopath/src/redis (go1)$ go install
go install flag: open /usr/local/go/pkg/darwin_amd64/flag.a: permission denied
~/prog/go/gopath/src/redis (go1)$ echo $GOPATH
<myhomedir>/prog/go/gopath
(where <myhomedir> is a valid path)
Question 1: why does go install not take $GOPATH into account?
Question 2: how to convince go install to use $GOPATH?

不确定你如何设置go，但有可能需要从标准库构建包，但由于权限问题无法进行。你可以尝试以下操作：
cd /usr/local/go/src
sudo ./all.bash
这将构建标准库并运行测试以确保一切正常。
确保你有适当的权限来读取和执行$GOROOT中所需的内容。个人建议只需从golang.org下载存档，并将其保存在~/local/go下，并相应地设置GOROOT。
英文:
Not sure how you setup go but it's possible that it needs to build packages from std library but can't due to permissions. You can try
cd /usr/local/go/src
sudo ./all.bash
This should build the std library and run tests to make sure everything is ok.
Make sure you have proper permissions to read and execute from $GOROOT as necessary. Personally I just download the archive from golang.org and keep it under ~/local/go and set GOROOT appropriately.

类似的问题在这里。当我检查我的$GOROOT时，我发现所有的库已经在那里构建好了。但是由于某些原因，它尝试重新构建所有的库。所以我只是做了一个小技巧：
find /usr/lib/go/pkg/ -name "*.*" | sudo xargs touch
然后一切都正常工作了。
英文:
Similar problems here. When I check my $GOROOT, I find that all the libraries are already built there. But for some reasons, it tries to rebuild all the libraries. So I just do a little trick:
find /usr/lib/go/pkg/ -name "*.*" | sudo xargs touch
Then everything just work fine.

我认为你需要的命令是"go get":
go get github.com/alphazero/Go-Redis
将会下载Go-Redis库并将其放入你的$GOPATH/src目录中。
go install会对你自己的源代码进行编译和安装。
我必须承认，我对这个概念有些困惑，但是仔细阅读"How to Write Go"和代码组织部分包含了关于go命令如何工作的所需知识。
英文:
I think the command you need is "go get":
go get github.com/alphazero/Go-Redis
will download the Go-Redis library and put it into your $GOPATH/src directory.
go install performs a compile and install on your own source code.
I must admit, I struggled with this whole concept for a bit, but a careful re-reading of "How to Write Go" and the code organization section contains what you need to know about how the go command works.

解决方案是从您的.bash_profile文件中删除GOROOT。然后，go命令将安装到您的GOPATH目录中。
而奇怪的是：当我再次在我的.bash_profile中设置GOROOT并创建一个新的shell时，它也起作用。
英文:
The solution is remove GOROOT from your .bash_profile. Then the go command will install it to your GOPATH directory.
And so strange is: when I set the GOROOT in my .bash_profile again and create a new shell, it also works.
