+      What's going on here?
+      ---------------------
+      Version 1.34.0 of Standard was set to depend on `~> 1.60' of RuboCop. This
+      constraint is too loose, and covers all minor versions of RuboCop 1.x.
+
+      "How do I fix this?", you might be asking.
+
+      How to fix this
+      ---------------
+      If you add a version specifier pinning `standard' to a version newer
+      than 1.35.1, Bundler will resolve appropriate versions of `standard',
+      `rubocop', and any other rubocop-dependent gems you may have installed.
+
+      1. Update your Gemfile to pin standard to be at least one such version:
+
+        gem "standard", ">= 1.35.1"
+
+      2. Run `bundle`, which will install and lock more appropriate versions
+
+        Example output:
+          Using rubocop 1.48.1 (was 1.49.0)
+          Using standard 1.26.0 (was 0.0.36)
+
+      This version (1.34.0.1) is an inoperative placeholder gem that exists
+      solely to print this message.
+
+      We're very sorry for this inconvenience!
