Steps to reproduce

What is expected?

Successful build.

What is actually happening?

SourceMap error, build hangs.

Dropping in a package-lock.json from yesterday fixed it.

A bug in terser 4.0.1 which was released hours ago. For npm users: run npm i terser@4.0.0 For yarn users: add the following field to package.json and then rerun yarn:

"resolutions": {
  "terser": "4.0.0"
}

I’m experiencing the same problem:

$ npm run build

> foo@0.1.0 build /tmp/foo
> vue-cli-service build

⠙  Building for production...Unhandled rejection Error: original.line and original.column are not numbers -- you probably meant to omit the original mapping entirely and only map the generated position. If so, pass null for the original mapping instead of an object with empty or null values.

For the time being, I disabled source maps as a workaround to get the project built:

vue.config.js

module.exports = {
    productionSourceMap: false
};
