无法用VSCode中的断点调试Golang
无法用VSCode中的断点调试Golang
提问于 2021-10-21 11:06:01
我在VS代码中调试带有断点的Golang应用程序。调试器抱怨找不到存在的文件。
你们中有人知道如何在VS代码中为Go应用程序启用断点吗？

我发现了问题。VS代码不能很好地处理符号链接。当我在VS代码中实际设置一个项目时，调试器就开始正常工作了。
gbajson@misio:~$ realpath /home/gbajson/Sync/clickr/clickr-node-api/clickr-node-api.go

想在这里分享我的解决方案。在阅读了一些github问题 vs-code-go之后，这个问题似乎是remotePath或substitutePath的结果。经过几次尝试，将remotePath设置为""终于成功了。
"version": "0.2.0",
"configurations": [
{
"name": "Connect to server",
"type": "go",
"request": "attach",
"mode": "remote",
"remotePath": "",
"port": 40000,
"host": "<host>",
}
]

这是gbajson回答的后续。
象征性的链接对我来说是个问题。在launch.json中使用此配置解决了这个问题，同时允许我保留符号链接：
{
"version": "0.2.0",
"configurations": [
{
"name": "Launch",
"type": "go",
"request": "launch",
"mode": "auto",
"program": "${workspaceFolder}/cmd/server/main.go",
"envFile": "${workspaceFolder}/.env",
"substitutePath": [
{
"from": "/home/me/go-workspaces",
"to": "/data/projects/workspaces"
}
]
}
]
}具体来说，它是"substitutePath“部分。
我的工作区目录实际上是从“/home/me/go- workspace”符号链接到真正的目录“/data/project/workspace”。
