 ### How to fix
 
-Deleting your node_modules and `package-lock.json` and re-running `npm i` should make sure that everything is created properly in the newly generated `package-lock.json`.
+1. If you are running your install command with `--no-optional`, try again without the flag.
+2. Delete your node_modules and `package-lock.json` and re-run `npm i`. This should have the `package-lock.json` file updated properly.
