ERROR EPERM: operation not permitted

The first to run this app is all right,but when I change something, then reload,I can't connect the server.
There are errors:
Bundling index.android.js
Updating 1 module in place, done
ERROR EPERM: operation not permitted, lstat 'F:\workspace\pepperoni-app-kit.git\index.lock'
{"errno":-4048,"code":"EPERM","syscall":"lstat","path":"F:\workspace\pepperoni-app-kit\.git\index.lock"}
