Go project with 2 executables
问题
大家好，我对Golang还比较新手，我正在编写一个玩具客户端和服务器应用程序，只是为了学习库。
但是我有一个项目文件夹：
philipherron@Philips-iMac {~/workspace/gospace/src/github.com/redbrain/station} $ echo $GOPATH
/Users/philipherron/workspace/gospace
我想要有两个可执行文件：
- client.go
- server.go
但是当我构建时，出现了以下错误：
philipherron@Philips-iMac {~/workspace/gospace/src/github.com/redbrain/station} $ go build github.com/redbrain/station/
# github.com/redbrain/station
./server.go:5: main redeclared in this block
previous declaration at ./client.go:5
我猜这是因为看起来我在同一个包中创建了两个main函数。
所以我尝试创建一个client和一个server子目录，并在每个目录中放置可执行文件，但是我得到了以下错误：
philipherron@Philips-iMac {~/workspace/gospace/src/github.com/redbrain/station} $ go build github.com/redbrain/station/client
go install github.com/redbrain/station/client: build output "client" already exists and is a directory
我猜这是因为我的目录结构是这样的：
$ tree
.
├── client
│ └── client.go
└── server
└── server.go
2 directories, 4 files
不确定如何解决这个问题，希望在同一个目录中同时拥有客户端和服务器，但也许这违背了我在Go中应该做的事情的规范？
英文:
Hi all I am fairly new to Golang, I am writing a toy client and server app just to learn the libraries.
But I have the project folder:
philipherron@Philips-iMac {~/workspace/gospace/src/github.com/redbrain/station} $ echo $GOPATH
/Users/philipherron/workspace/gospace
I wanted to have 2 binaries:
- client.go
- server.go
But when I build I get:
philipherron@Philips-iMac {~/workspace/gospace/src/github.com/redbrain/station} $ go build github.com/redbrain/station/
# github.com/redbrain/station
./server.go:5: main redeclared in this block
previous declaration at ./client.go:5
I guess this is because it looks like I am making to mains in the same package.
So I tried creating a client and a server subdir and have the binaries in each of those, but I get:
philipherron@Philips-iMac {~/workspace/gospace/src/github.com/redbrain/station} $ go build github.com/redbrain/station/client
go install github.com/redbrain/station/client: build output "client" already exists and is a directory
I guess this is because I have the layout of:
$ tree
.
├── client
│   └── client.go
└── server
└── server.go
2 directories, 4 files
Not sure how to get around this, it would just be nice to have the same client and server in the same directory but maybe this is against how I should be doing things in go?

只需将您的.go文件重命名即可。编译器试图写入'client'，但是'client'已经被目录占用。
$ tree
.
├── client
│ └── main.go
└── server
└── main.go
2 directories, 4 files
或者创建一个脚本，以不同的名称输出它们 go build -o client client/main.go。
英文:
just rename your .go files. The compiler is trying to write to 'client' but 'client' is already taken by the directory.
$ tree
.
├── client
│ └── main.go
└── server
└── main.go
2 directories, 4 files
And/Or create a script that outputs them with a different name go build -o client client/main.go

除了上面提到的单独的包之外，如果你设置GOBIN=$GOPATH/bin，它将在bin目录中创建客户端和服务器，并且不会与目录名称冲突。
英文:
along with with separate packages as above, if you set the GOBIN=$GOPATH/bin then it will create client and server in the bin dir and it will not collide with dir names
