[KIMRRR]

when I build packages, there were three types of error

I've only copied a portion of the error message because it's too long. I can give you the rest of the error if you need it. I'm not sure which part needs to be modified. I haven't made any modifications to the package you provided. Please give me a solution. Thank you

Hi @KIMRRR thanks for opening an issue. I will be able to help you better if you can copy paste the whole error message. You can paste it into a file and upload the file here by dragging and dropping into your comment.

Thank you for your quick response! error.zip

Hi @KIMRRR I tried to reproduce the error -- but everything is running fine on my machine. Can you try reinstalling the package and update the dependencies and run it again.

Closing this issue because of no responses. Feel free to open it again if things are not working :)
