travis cannot build because Error: Cannot find mod

The npm run test works fine locally.

However , travis insists that the build is failed and it shows the following log :

react-test-renderer is an implicit dependency in order to support react@15.5+. Please add the appropriate version to your devDependencies. See https://github.com/airbnb/enzyme#installation

Just ran into the same issue today as well.

looks like react-addons-test-utils was deprecated https://www.npmjs.com/package/react-addons-test-utils

You can probably get away with replacing that line in your package.json with
