It looks like the error came from the webpack configuration, but I'm not sure.
Can you provide the simplest online project as an example to reproduce this error so that I can track down the cause of the error?

I have created a repository named "project-test", which may be what you required. Hoping that you can help me solve the problem, thanks!

You can focus on the following points:

1. Compiling object-rest-spread syntax with babel. (this is the object-rest-spread statement of @geist-ui/vue that was not compiled)
2. babel does not compile the contents of node_modules by default. You can upgrade babel to version 7 and then use configuration file babel.config.js to compile the module from file node_modules. references: You want to compile node_modules?
