Electron Forge - Error: EBUSY: resource busy or locked, rmdir 'path'-CodePudding

When running npm run package, I got the following error:

An unhandled rejection has occurred inside Forge:
[Error: EBUSY: resource busy or locked, rmdir 'D:\Repos\app\out\app-win32-x64'] {
  errno: -4082,
  code: 'EBUSY',
  syscall: 'rmdir',
  path: 'D:\\Repos\\app\\out\\app-win32-x64'
}

Electron Forge was terminated. Location:
{}

What is causing this error, and how to solve it?

CodePudding user response：

Perhaps you forgot to call app.quit() and app.exe is still running in the background, kill all instances of app.exe then retry, the error should be gone.
