英文:
GOPATH and GOBIN set and exported in Fedora but still not installing program
问题
我在Fedora 21的笔记本上安装了GO，并设置了GOPATH和GOBIN，但由于某种原因，它不允许我安装我的GO程序。
我应该做什么才能让它工作？
--编辑--
按照下面所述的命令也会出错。
然而，我在尝试安装的go文件开头没有package main。一旦我将其更改为package main，它就可以工作了。不过，我不确定为什么不能使用其他包名。
英文:
I have GO installed on a Fedora 21 laptop and I setup GOPATH and GOBIN, but it for some reason is not letting me install my go Programs.
pred@computer01 [20:03:02] ~
$ echo $GOPATH
/home/pred/Documents/GO
pred@computer01 [20:03:11] ~
$ echo $GOBIN
/home/pred/Documents/GO/bin
pred@computer01 [20:03:15] ~
$ cd $GOPATH
pred@computer01 [20:03:21] ~/Documents/GO
$ go install src/github.com/pred3/go_helloworld/helloworld/helloworld.go
go install: no install location for .go files listed on command line (GOBIN not set)
pred@computer01 [20:03:32] ~/Documents/GO
$ go env
GOARCH="amd64"
GOBIN="/home/pred/Documents/GO/bin"
GOCHAR="6"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/pred/Documents/GO"
GORACE=""
GOROOT="/usr/lib/golang"
GOTOOLDIR="/usr/lib/golang/pkg/tool/linux_amd64"
CC="gcc"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0"
CXX="g++"
CGO_ENABLED="1"
What else should I be doing to get this to work?
--EDIT--
Issuing the following command as stated below also gave errors.
pred@computer1 [21:22:51] ~/Documents/GO
$ go install src/github.com/pred3/go_helloworld/helloworld
can't load package: package src/github.com/predatorian3/go_helloworld/helloworld: cannot find package "src/github.com/pred3/go_helloworld/helloworld" in any of:
/usr/lib/golang/src/src/github.com/pred3/go_helloworld/helloworld (from $GOROOT)
/home/pred/Documents/GO/src/src/github.com/pred3/go_helloworld/helloworld (from $GOPATH)
However, I did not have package main at the beginning of the go file I was trying to install. Once I changed it to package main it worked. I'm not sure why I couldn't use a different package name though.

go install 命令需要一个包作为参数（详细解释请参见包列表的描述）。在你的情况下，应该是：
go install github.com/pred3/go_helloworld/helloworld
假设 $GOPATH/src/github.com/pred3/go_helloworld/helloworld 目录存在，并且 $GOPATH/src/github.com/pred3/go_helloworld/helloworld/helloworld.go 文件以 package main 开头。
以下命令也可以实现相同的效果：
cd $GOPATH/src/github.com/pred3/go_helloworld/helloworld
go intsall
英文:
go install expects a package as argument (see Description of package lists for more detailed explanation). In your case it probably should be
go install github.com/pred3/go_helloworld/helloworld
assuming that $GOPATH/src/github.com/pred3/go_helloworld/helloworld directory exists and $GOPATH/src/github.com/pred3/go_helloworld/helloworld/helloworld.go starts with package main
The following commands will do the same:
cd $GOPATH/src/github.com/pred3/go_helloworld/helloworld
go intsall
