db:seed failure (<top required)

[vaceletm]

When I run db:seed on heroku I get an error at L84:

$ heroku run rake --trace db:seed
Running `rake --trace db:seed` attached to terminal... up, run.1306
Your Gemfile lists the gem capybara (>= 0) more than once.
You should probably keep only one of them.
While it's not a problem now, it could cause errors if you change the version of just one of them later.

Tasks: TOP => db:seed

seed.db seems aligned with the db schema, I don't know what's going on

[vaceletm]

It does the very same thing in local

[dboissier]

Have you tried to run db:migrate before db:seed ?

[vaceletm]

Yep, I followed instructions set in README.

[dboissier]

Recently, there were some changes in the schema so I think the current seed is outdated.
