The error you see is probably that you can't read the attribute initialize Method , It's an undefined , After looking at the source code , It is found that this method does not exist in the latest version , Later I saw the teacher's version, which is 3.2.0, My is 5.3.1

Switch versions , And then spoil it npm install

Remove warning after successful installation

Perform packaging again

Package successfully

see dist

You can see that there is index.html Of

And there are also id="app" Of div It's automatically inserted script label , Run it dist Medium html

There's no problem running
