Intermittent failure to resolve module after installation

[Jonny Buchanan]

The only reliable repro I can get is that this happens every single time I attempt to document nwb's --[auto-]install option with some example output:

λ preact run Lightbulb.js --install
Starting Webpack compilation...
Compiled successfully in 4153 ms.

The app is running at http://localhost:3000/
Recompiling...
Installing bootstrap...
Failed to compile with 1 error.

 ERROR  in ./Lightbulb.js
Module not found: Error: Cannot resolve module 'bootstrap/dist/css/bootstrap.css' in C:\Users\Jonny\tmp\preact-play

λ preact run Lightbulb.js --install

Compiled successfully in 17268 ms.

Running example/webpack1 I'm seeing:

ERROR in ./~/css-loader?{"localIdentName":"[name]-[local]--[hash:base64:5]"}!./lib/App/App.css
Module not found: Error: Cannot resolve module 'bootswatch/lumen/bootstrap.css' in C:\Users\Jonny\repos\npm-install-webpack-plugin\example\webpack1\lib\App
 @ ./~/css-loader?{"localIdentName":"[name]-[local]--[hash:base64:5]"}!./lib/App/App.css 3:10-151

Just a coincedence that it's CSS each time?

Here's css-loader again running example/webpack2 while testing some other changes - it succeeds in the end because if you open the app, it's styled. Is there some special handling needed?
