我试图像这样安装doozer:

$ goinstall github.com/ha/doozer

我得到这些错误。

goinstall: os: go/build: package could not be found locally goinstall: fmt: go/build: package could not be found locally goinstall: io: go/build: package could not be found locally goinstall: reflect: go/build: package could not be found locally goinstall: math: go/build: package could not be found locally goinstall: rand: go/build: package could not be found locally goinstall: url: go/build: package could not be found locally goinstall: net: go/build: package could not be found locally goinstall: sync: go/build: package could not be found locally goinstall: runtime: go/build: package could not be found locally goinstall: strings: go/build: package could not be found locally goinstall: sort: go/build: package could not be found locally goinstall: strconv: go/build: package could not be found locally goinstall: bytes: go/build: package could not be found locally goinstall: log: go/build: package could not be found locally goinstall: encoding/binary: go/build: package could not be found locally

运行go help environment,它有go env命令可以列出的每个环境变量的文档

具体到GOROOT, Go 1.9会自动将其设置到其安装路径。 即使你安装了多个Go,调用1.9。xone将GOROOT设置为/path/到/go/1.9(之前,如果没有设置,它假设默认路径为/usr/local/go或c:\ go)。

参见CL Go Review 53370:

The go tool will now use the path from which it was invoked to attempt to locate the root of the Go install tree. This means that if the entire Go installation is moved to a new location, the go tool should continue to work as usual. This may be overriden by setting GOROOT in the environment, which should only be done in unusual circumstances. Note that this does not affect the result of the runtime.GOROOT() function, which will continue to report the original installation location; this may be fixed in later releases.

在osx中,我安装了brew,下面是适合我的设置

GOPATH="$HOME/my_go_work_space" //make sure you have this folder created

GOROOT="/usr/local/Cellar/go/1.10/libexec"

还有一种情况是,当我们使用go时,它会编译所有的go文件。

假设我们有一个文件main。然后我们将当前文件更改为main_old。Go,然后添加新的main。文件。然后当我们构建应用程序时,所有的go文件都将被编译。所以发生的错误可能是由于其他go文件中的编译错误。

GOPATH的讨论如下:

GOPATH环境变量 GOPATH可以设置为一个以冒号分隔的路径列表,其中Go 可以找到代码、包对象和可执行文件。 设置GOPATH使用goinstall来构建和安装您自己的代码和 Go树之外的外部库(并避免写入 makefile)。

这里讨论的是GOROOT:

$GOROOT Go树的根,通常是$HOME/ Go。默认为 目录的父目录。Bash运行。如果你选择不去的话 设置$GOROOT时,必须运行gomake而不是make或gmake 使用传统的makefile开发Go程序。

安装Go lang之后,GOROOT是安装的根目录。

当我在Windows C:\目录中分解Go Lang二进制时,我的GOROOT应该是C:\ Go。 如果安装Windows安装程序,它可能是C:\Program Files\go(或C:\Program Files (x86)\ go, 64位包)

 GOROOT = C:\go

而我的GOPATH是Go lang源代码或工作区的位置。

如果我的Go lang源代码位于C:\Users\\GO_Workspace,那么你的GOPATH将如下所示:

 GOPATH = C:\Users\<xyz>\GO_Workspace
