VsCode Go 扩展调试 Example_c.c 文件而不是实际文件

VsCode Go extension debugs Example_c.c file instead of actual file

我刚刚尝试在 C:\Scripts\hello_world.go 文件中从 VSCode 1.28.2 (Windows 8.1) 执行 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

go get -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 设置是:

  // 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

所以我自定义了VSCode的变量如下:

{
    "editor.renderControlCharacters": false,
    "go.inferGopath": true,
    "go.goroot": "C:\go",
}

现在这是奇怪的部分。当我按下 Ctrl+F5 时,编译会获取一个 "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它存在):

我已经尝试删除所有临时文件并重新启动 VsCode 多次。设置 Go 环境来调试 hello world 的整个体验真的很令人失望。

我还能检查什么?有什么提示吗?

您的 GOPATH 应指向 "C:\Scripts"。然后在调试模式下将launch.json中的"program"变量指向"C:\Scripts"到运行。
