@yyx990803 I kind of figured it out. This problem has nothing to do with 'dev mode' but with OS. I'm using Windows and the compiler machine is Linux.

vue-cli/packages/@vue/cli-plugin-babel/index.js

Line 20 in b20f624

if (options.transpileDependencies.some(dep => filepath.match(dep))) {

On windows, modules with a namespace (eg: @my/module) won't match in the above code.
