Build fails missing node-sass

[oskarrough]

Hi, if an app uses node-sass and https://github.com/n1ru4l/ember-cli-css-preprocess it fails to build on heroku. I assume it's because the node-sass dependency doesn't get installed. I have it in devDependencies.

What to do? Any help would appreciated, thank you!

@oskarrough are you using yarn?

[oskarrough]

@Dhaulagiri yes?

This is likely an issue upstream in either the node buildpack or yarn itself from our experience. We had a similar problem that can be solved by either setting the NODE_MODULES_CACHE config var to false or adding a postinstall script postinstall: "npm rebuild" to your package.json.

Thank you, probably. As it was working before.

So I tried replacing ember-cli-css-preprocess + node-sass with ember-cli-sass (which also uses node-sass) + ember-cli-postcss and now it builds on Heroku. FastBoot and all. Happy camper!

@oskarrough sweet. I think this is related to this issue.
