I know the [unmet dependencies can be ignored](https://discourse.roots.io/t/npm-debugging-guidelines-failed-npm-install-bower-install-or-gulp-build-read-this/3060), but I made some progress by editing

```
wp-content/themes/rhc2015/package.json
```

Changing the row

```
"gulp-autoprefixer": "^2.1.0",
```

to

```
"gulp-autoprefixer": "^2.3.0",
```

and changing

```
"browser-sync": "^2.7.1",
```

to

```
"browser-sync": "^2.7.10",
```

Removes the ‘minimist’ and ‘browser-sync’ errors and instead shows a different module as being problematic:

```
$ gulp
module.js:338
    throw err;
          ^
Error: Cannot find module 'process-nextick-args'
    at Function.Module._resolveFilename (module.js:336:15)
    at Function.Module._load (module.js:278:25)
    at Module.require (module.js:365:17)
    at require (module.js:384:17)
    at Object.<anonymous> (/usr/share/nginx/html/wp-content/themes/rhc2015/node_modules/gulp-changed/node_modules/gulp-util/node_modules/through2/node_modules/readable-stream/lib/_stream_duplex.js:20:23)
    at Module._compile (module.js:460:26)
    at Object.Module._extensions..js (module.js:478:10)
    at Module.load (module.js:355:32)
    at Function.Module._load (module.js:310:12)
    at Module.require (module.js:365:17)
```

However, ‘gulp-changed’ is at it’s latest version so I can’t up the required version in package.json.
