**FIXED!**  
**Building without cache solved this problem.**

I’m trying to integrate CircleCI to this [open source project](https://github.com/FeliciousX/xstream-boilerplate) .  
It’s using:-

- webpack to bundle the js
- babel to transpile es2015 to es5
- Mocha + power-assert - unit testing
- Nightwatch + Mocha - integration testing

When running the unit-test, it will say `@cycle/xstream-adapter` module not found.  
I tried running locally, I even tried it on Travis CI. It works.

So I SSH-ed in and run the node cli on the repo directory to test. `require('@cycle/xstream-adapter')` and sure enough it cant be found.

I ran `npm list | grep @cycle` and I see xstream-adapter is a dependency for `@cycle/dom` so normally it would still work

Next I manually `npm install @cycle/xstream-adapter` and manually run the `npm run unit-test`

This time it is able to find the xstream adapter but have other errors. Shown down below.

I am starting to think that there’s something wrong here with how node resolve the modules in CircleCI ?  
Anyone experienced anything similar before?

Hmm after clearing cache and editing my circle.yml it worked.

Now to make selenium driver run in the background…
