Courses Plus Student 7,563 PointsHi, so mysql recently updated to version 0.4.0. Rails depends on the version being 0.3.x even though rails new project generates an unbound dependency—which would resolve to the latest version (0.4.0).
Rails has patched it and provided a back port but that version hasn't been released yet. So whenever they release the new version the issue will go away.
There are a few things you could do.
- Go into you gems file and add a version constraint to mysql2 like so:
gem "mysql2", "~> 0.3.0" # Note the last .0 that's essential - Use rails master. This isn't a great options for a million reasons and is probably unnecessary for you but technically you could do this.
