rails 6 ActiveRecord not compatible version

How I can fix not compatible version?
```
Bundler could not find compatible versions for gem "activerecord":
  In Gemfile:
    activerecord-jsonb-associations was resolved to 0.2.0, which depends on
      activerecord (~> 5.1.0)

    rails (~> 6.0.3, >= 6.0.3.4) was resolved to 6.0.3.4, which depends on
      activerecord (= 6.0.3.4)
```
