Gem file is requesting dependencies that are installed when upgrading from Rails 4 to Rails 5 but it says it could not find compatible versions-Twitter bootstrap

This is my first major upgrade of Rails (v4 to v5). I’ve done minor upgrades, like 4.1.1 to 4.2 etc…

I’ve upgraded to 5.1.1, and I’m getting this dependency error in the console

Bundler could not find compatible versions for gem "actionmailer":
  In Gemfile:
    mail_form (= 1.7.0) was resolved to 1.7.0, which depends on
      actionmailer (< 5.2, >= 3.2)

    rails (>= 5.1.1, ~> 5.1) was resolved to 5.1.1, which depends on
      actionmailer (= 5.1.1)

however, I have actionmailer 5.1.1 installed. That looks like what it’s asking for. These seems like an noob question, but it looks like rails MUST have actionmailer 5.1.1 and mail_form can have version less than 5.2 or equal/greater than 3.2. 5.1.1 satisfies both these conditions….so what’s going on?

It also says this further down

Could not find gem 'rails (>= 5.1.1, ~> 5.1)' in any of the sources.

But I’ve uninstalled and reinstalled rails 5.1.1 to make sure.

I also tried doing this with 5.0.0 and had the same issue.

This is just one of many, many “Bundler could not find compatible versions for gem ” errors in this bundle.
