Error in command line：

This dependency was not found:

regenerator-runtime/runtime in ./node_modules/cache-loader/dist/cjs.js??ref--12-0!./node_modules/babel-loader/lib!./node_modules/cache-loader/dist/cjs.js??ref--0-0!./node_modules/vue-loader/lib??vue-loader-options!./src/components/HelloWorld.vue?vue&type=script&lang=js&

I thought regenerator-runtime has already been installed in ./node_modules/@vue/babel-preset-app. Shouldn't this regenerator-runtime be found in @vue/babel-preset-app ?

Removing node_modules & package-lock.json and rerunning npm install fixes this issue.

Yeah, nuking package-lock.json and updating all versions just to fix this probably isn't the best idea. Not sure why that is so upvoted.

Deleting node_modules and package-lock.json did not fix it for me. I'm using pnpm, maybe its stricter handling of dependencies caused that not to work? I did pnpm i --save regenerator-runtime and that fixed it (I tried pnpm install --save regenerator-runtime/runtime as indicated by the error message but that failed to install).
