VScode-Go can't load package: package .: no buildable Go source files in

在VScode中调试Go程序时提示：

can't load package: package .: no buildable Go source files in d:\my_workspace\go_ws

exit status 1

Process exiting with code: 1

lauch.json配置如下：

{

"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

}]

}

问题出在"program": "${workspaceRoot}\\",将其修改为项目路径，则错误解决。
