Actually I discovered that I can add Ruby version to `Gemfile` while troubleshooting [the problem with `.ruby-version`](https://travis-ci.community/t/travis-cannot-find-a-ruby-2-5-0-from-ruby-version/6853).

If Ruby version is not specified explicitly, why not let RVM choose Ruby version [like it does locally](https://rvm.io/workflow/projects)? Then it will not be necessary to maintain additional integration code.

I believe this default command prevents `rvm` from looking into `Gemfile`.

```auto
$ rvm use default

```

If it can be replaced with command that triggers default `rvm` behavior, then in presence of `.ruby-version` the following will be unnecessary too.

```auto
rvm use $(< .ruby-version) --install --binary --fuzzy

```
