Node-sass: 4.5.3 regression on Travis CI breaks builds

[bjornharrtell]

The failure is Error: ENOENT: no such file or directory, scandir '.../node_modules/node-sass/vendor. Downgrading to version 4.5.2 resolves the issue.

Cannot reproduce locally and as it's a managed environment I can only extract some of the version information from the build log:

$ node --version
v6.10.3
$ npm --version
3.10.10
$ nvm --version
0.33.2

Travis configuration:
https://github.com/miguelcobain/ember-paper/blob/cef52e7638615e44249775b0663ba8f48d7bb8c1/.travis.yml

Failing job:
https://travis-ci.org/miguelcobain/ember-paper/jobs/233735922

Successful job:
https://travis-ci.org/miguelcobain/ember-paper/jobs/233735922

The only difference is the node-sass version.

The only think 4.5.3 added as support for another module version of Node 8 https://github.com/sass/node-sass/compare/v4.5.2...v4.5.3
This looks like another general yarn caching issue https://github.com/sass/node-sass/issues/1804

Sounds like a reasonable explanation but using --force or removing Yarn cache usage in .travis.yml does not appear to help.

Please file an issue with yarn. They're actively trying to address
node-sass incompatibilities

Confirmed to be more or less the same issue as described in https://github.com/yarnpkg/yarn/issues/1981. The workaround npm rebuild node-sass run as the postinstall script works in my case too. Sorry for the noise.

[StfBauer]

Had the same issue but instead of adding it inside the package.json a put the following code in the .travis.yml

before_script: npm rebuild node-sass;

Works great for me.
