我只是试图从VSCode 1.28.2(Windows 8.1)在C:\ Scripts \ hello_world.go文件中执行一个Hello World:
package main
import (
"fmt"
)
func main() {
fmt.Println("Hello, Gopher!")
}
我的环境如下:
$ go version go version go1.11.2 windows/amd64
去-u github.com/derekparker/delve/cmd/dlv
C:\Scripts>go run hello_world.go Hello, Gopher!
在VSCode设置中,我的全局go.gopath和go.goroot设置为:
// Specify GOPATH here to override the one that is set as environment variable. The inferred GOPATH from workspace root overrides this, if go.inferGopath is set to true.
"go.gopath": null
// Specifies the GOROOT to use when no environment variable is set.
"go.goroot": null
因此,我自定义了VSCode中的变量,如下所示:
{
"editor.renderControlCharacters": false,
"go.inferGopath": true,
"go.goroot": "C:\\go",
}
现在这是很奇怪的部分。当我按Ctrl + F5组合键时,编译将使用“ Example_c.c”文件(?),并报告该文件的错误(我从未创建过,甚至不知道存在):

我已经尝试删除所有临时文件,并多次重新启动VsCode。设置Go环境以调试Hello World的整个体验确实令人失望。
我还能检查什么?有提示吗?
答案 0 :(得分:0)
您的GOPATH应该指向“ C:\ Scripts”。然后将launch.json中的“程序”变量指向“ C:\ Scripts”,以在调试模式下运行它。
