Installed godoc after altering GOPATH, now do I need what it put in my GOPATH?
问题
在按照教程操作时，当要求我运行godoc时，出现了问题，它找不到。
经过一番搜索，我发现：
- godoc在1.2版本中已经更改，成为了一个独立的库和二进制文件。
- 你必须通过"go get"来获取它，但没有设置GOPATH是行不通的。
- 二进制安装似乎包含了godoc？我是从源代码安装的，所以默认情况下不包含它。
我将GOPATH导出到了当前应用程序路径/home/me/go_project/test。GOROOT已经设置好了。（注意：GOPATH不喜欢与GOROOT设置为相同）
之后，我运行了"go get code.google.com/p/go.tools/cmd/godoc"，它将二进制文件安装到了我的GOROOT/bin目录下（太好了！）
它还在我的/home/me/go_project/test/src/code.google.com/p...下创建了一个pkg安装目录（嗯...是什么？）
我真的不需要在我的测试应用程序下保留那个code.google...的部分；Go是否需要保留它？它不会改变库路径、依赖关系或其他任何东西，对吗？
基本上...我可以只使用它放在GOROOT/bin下的二进制文件，并删除它放在我的go_project应用程序目录下的东西，而不会影响Go吗？
英文:
While following a tutorial I hit a wall when it wanted me to run godoc. It was missing.
After a bit of searching around, I discovered:
- godoc has been changed for 1.2, so it's a separate library and
binary. - You have to get it through "go get", which won't work without
GOPATH. - Binary installations apparently include godoc? I installed
from source, so it's not included by default.
I exported a GOPATH to my current application path /home/me/go_project/test. GOROOT was already set. (Note: GOPATH doesn't like to be set the same as GOROOT)
After that I ran "go get code.google.com/p/go.tools/cmd/godoc" and it dutifully installed the binary into my GOROOT/bin (yay!)
It also created a pkg installation under my /home/me/go_project/test/src/code.google.com/p... (Um...wat?)
I really don't need that code.google... bit under my test application; is there any reason Go would need that kept there? It doesn't alter anything in library paths or dependencies or anything, does it?
Essentially...can I just use the binary it put in GOROOT/bin and erase the stuff it put under my go_project application directory without affecting Go?

是的，Go二进制文件是静态链接的（几乎是的）。你可以只使用GOROOT/bin目录下的二进制文件，而不会影响Go，可以删除go_project应用程序目录下的内容。

Yes. Go binaries are statically linked (almost).

你的问题的答案是肯定的。然而，如果你计划进行大量的Go开发，最终你会想要设置一个GOPATH。更新Godoc到新版本将需要它。任何你可能需要的开发工作的包最好安装到GOPATH中。
我建议你果断行动，设置一个GOPATH。
英文:
Tbe answer to your question is yes. However if you plan on doing much Go dev you are going to want to setup a GOPATH eventually. Updating Godoc to a new version will need it. Any packages you might want for your dev work will be best installed into a GOPATH.
I would just bite the bullet and set one up.
