debugging - VSCode 调试 golang。深入调试器

Question

我在使用 Visual Studio Code 中的 Delve 调试器时遇到问题。调试开始但没有任何反应。控制台中只有信息:

time="2018-06-23T16:35:55+02:00" level=info msg="launching process with args: [C:\\Users\\LenovoPC\\go\\src\\test\\debug]" layer=debugger

launch.json的配置

"version": "0.2.0",
"configurations": [
    {
        "name": "Launch",
        "type": "go",
        "request": "launch",
        "mode": "debug",
        "remotePath": "",
        "port": 2345,
        "host": "127.0.0.1",
        "program": "${workspaceRoot}",
        "env": {},
        "args": [],
        "showLog": true
    }
]

Based on how you install delve it will either end up in your PATH or GOPATH/bin. If dlv binary is in your GOPATH/bin and this GOPATH is not set as an environment variable, then make sure your PATH points to this GOPATH/bin so that the Go extension can find the dlv binary.

尝试将目录更改为文件名以从项目文件夹的 main.go 运行项目

{
    "version": "0.2.0",
    "configurations": [

        {
            "name": "Launch",
            "type": "go",
            "request": "launch",
            "mode": "debug",
            "remotePath": "",
            "port": 2345,
            "host": "127.0.0.1",
            "program": "${fileDirname}",
            "env": {},
            "args": [],
            "showLog": true
        }
    ]
}

确保 $GOPATH 已设置(例如 ~/.go)在终端运行命令

go env

检查 GOROOT 和 GOPATH 变量以查看 delve 是否与它们同步
