javascript - vue cli - Uncaught SyntaxError: Unexpected token <

I create my project with vue-cli 3.0. Initially it runs ok. But after I <ctrl>-c then npm run serve again, it keep throwing error:

Uncaught SyntaxError: Unexpected token <

it indicate that the error happened at the first line of app.js, but I check in console the < is actually from index.html. Which means somewhere along the process, the webpack thought index.html should be transpile as app.js.

Below are the packages I am using:

vue 3.0.0-rc.3 @vue/cli-plugin-babel ^3.0.0-beta.15 @vue/cli-plugin-eslint ^3.0.0-beta.15 @vue/cli-service ^3.0.0-beta.15

How can I resolve this?

Update01 I delete the whole node-modules folder and npm install again, then everything seems to work fine again. But if anyone have any idea why this happen, please share it.

Try by adding <base href="/" /> into the <head> of your index.html. Hope it will work.
