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

您不需要显式地设置GOROOT(现代版本的Go可以根据您运行的Go二进制文件的位置自行确定)。

另外,当尝试使用vgo工作时,得到了跟随错误:

go: modules disabled inside GOPATH/src by GO111MODULE=auto; see 'go help modules'

删除GOROOT,更新我的GOPATH和导出GO111MODULE=“on”解决了这个问题。

看这里

GOPATH可以设置为一个以冒号分隔的路径列表,其中可以找到Go代码、包对象和可执行文件。 设置GOPATH使用goinstall在Go树之外构建和安装自己的代码和外部库(并避免编写makefile)。

其他回答

如果你正在使用发行版go,你应该指向包含文件的位置,例如:

$ rpm -ql golang | grep include
/usr/lib/golang/include

(这是针对Fedora 20)

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.

不建议使用GOPATH和GOROOT配置。

您可以使用GO模块。

例如:

mkdir go_app
cd go_app
go mod init go_app

对于所有新手,如果你正在使用Ubuntu,他们可以简单地导出GOPATH=$HOME/go,或者去帮助GOPATH获取更多信息。

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
