Hi,

I’ve cloned [serverless-stack-demo-ext-api](https://github.com/AnomalyInnovations/serverless-stack-demo-ext-api/blob/master/package.json), I’ve installed all the dependences but when I try to run `./startServer` I got this error

```
$ ./startServer 
internal/modules/cjs/loader.js:613
    throw err;
    ^

Error: Cannot find module 'http-proxy'
Require stack:

    at Function.Module._load (internal/modules/cjs/loader.js:555:12)
    at Function.Module.runMain (internal/modules/cjs/loader.js:826:10)

```

so I’ve also installed `http-proxy` as a dev dependency. After that if I run again the command I get this error:

```
$ ./startServer
events.js:173
      throw er; // Unhandled 'error' event
      ^

    [... lines matching original stack trace ...]
    at internal/main/run_main_module.js:17:11

```

what’s the problem? am I missing something? how can I solve it?

I see you’ve opened a GitHub issue for this as well. I replied there.
