I had this issue on windows 10 too, fixed it by giving yarn a try (npm install yarn -g) and then running yarn to update/install the dependencies instead of npm. Now it works with no errors.

This error occurred to me when I tried to use a for ...of loop in my code

ERROR in ./~/buble-loader!./~/vue-loader/lib/selector.js?type=script&index=0!./resources/assets/js/contractuals/components/ApplicantForm.vue
Module build failed: Error

Then I tried to clean my node_modules directory, upgrade node and npm install again the packages but with no luck

Then I tried to follow @benjackson 's proposed solution and yarn add buble-loader After this I run gulp again and I got a different error

{ [Error: ./~/buble-loader!./~/vue-loader/lib/selector.js?type=script&index=0!./resources/assets/js/contractuals/components/ApplicantForm.vue

for...of statements are not supported. Use `transforms: { forOf: false }` to skip transformation and disable this error, or `transforms: { dangerousForOf: true }` if you know what you're doing (1089:16)
Error

I shall try to dig further into this error and look if I can find a solution
