Golang VScode debug设置

尝试vscode debug ，但是遇到下面错误

DAP server listening at: 127.0.0.1:62253
Build Error: go build -o C:\GoProject\kb-api-gateway\src\__debug_bin.exe -gcflags all=-N -l .\server.go
go: gopkg.in/guregu/null.v4@v4.0.0: missing go.sum entry; to add it:
	go mod download gopkg.in/guregu/null.v4 (exit status 1)

Solution:
run 下面命令， download 依赖

go mod tidy
或者
go mod download

output:

各人情况不一样

把launch.json 中 mod改为 auto

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.

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

        {
            "name": "Launch file",
            "type": "go",
            "request": "launch",
            //改为auto
            "mode": "auto",
            "program": "${workspaceFolder}\\src\\server.go",
            "cwd": "${workspaceFolder}",
            //"envFile": "${workspaceFolder}\\****\\***\\application.env",
            "env": {
                "DB_HOST":"*************",
                "DB_PORT":"*****",
                "DB_SCHEMA":"****",
                "DB_USERNAME":"****",
                "DB_PASSWORD":"****",
            },
            "args": [
                "-env","dev",
            ]
        }
    ]
}

然后基本就解决了
