我试图像这样安装doozer:

$ goinstall github.com/ha/doozer

我得到这些错误。

截至2020年和Go版本1.13+,在Windows中更新GOPATH的最佳方法是在命令提示符中输入:

setx GOPATH C:\mynewgopath

其他回答

我读了go help gopath文档,仍然非常困惑,但从另一个go文档页面中发现了这个小块:

GOPATH环境变量指定工作空间的位置。它可能是开发Go代码时需要设置的唯一环境变量。

http://golang.org/doc/code.html#GOPATH

第一次运行go env。 如果你看到go没有安装,你可以通过homebrew或包和/或其他方式安装它。 如果您看到输出,那么您的Go已经安装。 它向你展示了所有已设置和未设置的env。

如果你看到GOROOT为空:

在我的电脑上:/usr/local/go/bin/go 然后export GOROOT=/usr/local/go

如果你看到GOPATH为空:

在计算机的任何位置为go项目创建任意目录,在我的例子中是:~/GO_PROJECTS 然后导出GOPATH=~/GO_PROJECTS

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.

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

如上所述:

GOPATH环境变量指定您的 工作区。

对于Windows,这对我来说是有效的(在Ms-dos窗口中):

set GOPATH=D:\my_folder_for_go_code\

这将创建一个Ms-dos识别的GOPATH变量,使用如下:

cd %GOPATH%
