图里的路径和 `config_machine.json` 里的路径都是正确的，找了同学要来了他的版本，能正常运行，但似乎我还是不懂为什么同学的配置可以图里的就不可以？
```json
{
"configurations": [
{
"name": "RISC-V: Debug on URIscV",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceRoot}/project/uriscv/kernel",
"MIMode": "gdb",
"miDebuggerPath": "/opt/riscv/bin/riscv32-unknown-linux-gnu-gdb",
"miDebuggerServerAddress": "localhost:8080",
"stopAtEntry": false,
"stopAtConnect": true,
"cwd": "."
}
]
}
```
