How should I solve it? If you can help me, I will be very grateful
Here are the details：

Thanks for letting me know about this problem. Unfortunately I'm still working on a second alpha version, which turned out to be again almost a complete rewrite (see also #9). Therefore I won't fix anything in v0.4.0-alpha.0. I'm still in the phase of getting the code actually working and I don't feel comfortable yet with pushing anything to GitHub.

For now, I recommend to use version v0.3.1. If you need a special feature from v0.4.0-alpha.0, I can only suggest to wait (maybe tell me what you need to make sure that I have it in the next alpha), or implement it yourself for 0.3.x and issue a PR.
