Syntax Error: Thread Loader(Worker 1)

Cannot read properties of undefined (reading 'options')

framework: @vue/cli@5 + [email protected] + ts

vue-cli uses wokrer-loader to load a web woker, using npm run build has a high chance of failing to package it with the error reported above.

There is a conflict between thread-loader and worker-loader.

Solution:

vue.config.js configure parallel: false . Build the official environment with thread-loader turned off.
