On the homepage I required Headroom from headroom.js and Vimeo's player from @vimeo/player. Running the app in dev mode with npm start works as expected. Building the app with either npm run build or serving it with npm run serve throws an error about the modules not being found.
It seems to search in the src folder instead of node_modules.
Template execution failed: Error: ENOENT: no such file or directory, open '/Users/rijkvanzanten/Development/import-demo/src/~/@vimeo/player/dist/player.js'
