Can't use scoped npm packages

[cmmartin]

If I try to run docker-compose up with a scoped npm dependency like @google-cloud/language, I get the following error after build...

api_1    | Finished 'build' after 2357ms
api_1    | module.js:538
api_1    |     throw err;
api_1    |     ^
api_1    | 
api_1    | Error: Cannot find module '@google-cloud/language'
api_1    |     at Function.Module._resolveFilename (module.js:536:15)

I think maybe this is due to the nested directory structure in scoped package. The package exists at node_modules/@google-cloud/language instead of at the top level of node_modules

This ended up being an issue with @google-cloud/language and isn't related to this project
