【问题描述】:
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:
- 我使用 Windows 安装程序从头开始安装 Go:
$ go version go version go1.11.2 windows/amd64
- 安装在 C:\Go
- 已安装 VSCode Go 扩展:https://marketplace.visualstudio.com/items?itemName=ms-vscode.Go
- 已安装调试器:
去获取 -u github.com/derekparker/delve/cmd/dlv
- 使用 SystemPropertiesAdvanced 检查:
- 局部变量 GOPATH = %USERPROFILE%\go
- 局部变量 PATH 添加 %USERPROFILE%\go\bin
- 系统变量 PATH 添加 C:\Go\bin
- 系统变量 GOROOT = C:\Go\
- 我有 MinGW64、GitBash 和 MinGW 1.0(但我看不出这会如何影响从 VSCode 运行 Go)
- 从 cmd.exe 运行程序完全没有问题:
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
所以我从 VSCode 自定义变量如下:
{
"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 环境来调试 hello world 的整个体验真的令人失望。
我还能检查什么?有什么提示吗?
