Error in Travis CI: cannot find module '@semantic-release/changelog'

[Tal Ohana]

Maybe I am missing something, but in my library: https://github.com/talohana/ngx-storage-api I am using semantic-release.
I added @semantic-release/changelog just as described in the docs, locally the dry-run runs correctly but in the CI (travis-ci) environment I get:

An error occurred while running semantic-release: Error: Cannot find module '@semantic-release/changelog'

install:

• npm install -g codecov

you've overridden the default install step in your travis config, meaning that your dependencies are not being installed. i'm guessing the ones that are available are from the cache of builds that ran before this change
