+Ruby makes using emacs a challenge.
+
+Flycheck likes to complain about `bundle exec` even on emacs 27.1+. There are a few things you need to do to make things work nicely:
+
+1. Use `lsp-mode` instead of robe and launch a ruby server with that. For some reason robe gets in the way of things like `.dir-locals.el`.
+2. On a per-project basis, put a `.dir-locals.el` file with the following in it:
+
+```
+((ruby-mode . ((eval . (setq flycheck-command-wrapper-function
+                             (lambda (command)
+                               (append '("bundle" "exec") command)))))))
+```
+
+Which will allow bundle exec to work with flycheck.
