英文:
Download and prepare go package's dependencies to be used on another, isolated machine
问题
我有两台机器：Alice 和 Bob。Alice 不连接网络，而 Bob 连接网络。
我想在 Alice 上构建和运行一个 Go 程序，但它需要多个依赖项。有没有一种方便的方法可以从 Bob 准备所有这些依赖项，这样我只需要将一个目录从 Bob 复制到 Alice，然后在 Alice 上运行 go build？
英文:
I've got two machines: Alice and Bob. Alice is not connected to the network, Bob is.
I'd like to build and run a go program on Alice, but it requires multiple dependencies. Is there a convenient way to prepare all those dependencies from Bob so I just have to copy one directory from Bob to Alice and run go build (on Alice)?

所有编译的源代码都在$GOPATH中。将其复制到Alice将为您提供重建软件包所需的一切。由于您的源代码也应该在$GOPATH中，所以不需要复制其他内容。
如果您使用的是go1.6+或带有GO15VENDOREXPERIMENT=1的go1.5，您可以将所有依赖项放入项目的vendor/子目录中，以便将它们一起打包。
在go中进行交叉编译也非常简单（除非您需要cgo），只需设置GOOS和GOARCH环境变量即可。
Go构建参考文档：https://golang.org/pkg/go/build/

英文:
All the source for compilation is in $GOPATH. Copying that to Alice will give you everything you need to rebuild the package. Since your source should be in $GOPATH as well, there shouldn't be anything else to copy.
If you're using go1.6+, or go1.5 with GO15VENDOREXPERIMENT=1, you can put all the dependencies into a vendor/ subdirectory of your project, to package them together.
Cross-compilation is also very easy in go (unless you require cgo), by setting the GOOS and GOARCH environment variables.
