title: How to debug with `nodemon` in nuclide? The breakpoint doesn't hit
body: <p>I'm a JS noob looking for some help:-) I'm trying to learn nuclide's debugger follow the official doc. The source code is from <a href="https://github.com/facebook/flow/tree/master/examples" rel="nofollow noreferrer">flow's five examples'</a> <code>hello.js</code>.</p>
  
  <p>I started with executing the following command:
  <code>nodemon ./01_HelloWorld/hello.js --exec babel-node</code></p>
  
  <p>Then I successfully attached the debugger to this process. The console also printed 
  <code>Starting debugger agent.
  Debugger listening on 127.0.0.1:5858</code></p>
  
  <p>I added a breakpoint on the 4th line <code>return x*10</code>. However, no matter what I do the program just doesn't hit the breakpoint. </p>
  
  <p>I know that in google dev tools the program will hit breakpoints after <code>refresh</code>. How can I do something similar to <code>refresh</code>? Would you please tell me what's the next step should I do? Many thanks!</p>
