Rails での testのエラー

Question

Railsでテストをしようしているのですが、下記のエラーが出ます。
よろしくお願いいたします。

ターミナル
Bundler could not find compatible versions for gem "actionview":
In snapshot (Gemfile.lock):
actionview (= 6.0.1)

In Gemfile:
rails (~> 6.0.1) was resolved to 6.0.1, which depends on
actionview (= 6.0.1)

rails-controller-testing (= 1.0.2) was resolved to 1.0.2, which depends on
  actionview (~> 5.x, >= 5.0.1)

web-console (>= 3.3.0) was resolved to 4.0.1, which depends on
  actionview (>= 6.0.0)

Running bundle update will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.
