我试图像这样安装doozer:

$ goinstall github.com/ha/doozer

我得到这些错误。

在cmd/go文档中讨论了GOPATH:

GOPATH环境变量列出了寻找Go代码的位置。在 Unix,值是一个冒号分隔的字符串。Windows操作系统为 以分号分隔的字符串。在Plan 9中,取值为列表。 必须将GOPATH设置为在外部获取、构建和安装包 标准围棋树。

安装说明中讨论了GOROOT:

The Go binary distributions assume they will be installed in /usr/local/go (or c:\Go under Windows), but it is possible to install the Go tools to a different location. In this case you must set the GOROOT environment variable to point to the directory in which it was installed. For example, if you installed Go to your home directory you should add the following commands to $HOME/.profile: export GOROOT=$HOME/go export PATH=$PATH:$GOROOT/bin Note: GOROOT must be set only when installing to a custom location.

其他回答

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

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

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。

这里有一个解决方案(单用户):

GOROOT=$HOME/.local # your go executable is in $GOROOT/bin
GOPATH=$HOME/.gopath
PATH=$GOROOT/bin:$GOPATH/bin:$PATH

如果你把。gopath改成。Go, Go会报错。

我希望他们能像运货员那样,把所有东西都放在一个地方。

你可以使用一个命令:go env GOPATH
