Troubleshooting

Here are some common problems and how to solve them.

Cannot find module '@babel/compat-data/corejs3-shipped-proposals'

This is caused by a compatibility issue between a version of @babel/preset-env that an older release of Laravel Mix required, and certain versions of node.

Fix

yarn upgrade laravel-mix

This will upgrade your installation of laravel-mix to a version that requires @babel/preset-env: ^7.9. You shouldn't have to change anything else, since this upgrade is a non-breaking change.

Cannot find name 'describe' / Cannot find name 'test'

This is your TypeScript checker finding methods that it does not have types for.

Fix

You should add "include": ["resources/**/*"] to your tsconfig.json (edit the path to where you manage your JS), or add "exclude": ["vendor"]. This doesn't normally happen with other libraries because node_modules is excluded from type checking by default.
