Import vux.css reports an error

according to the code written in the vux document,
reported an error when it was running, and no one on Baidu seemed to have encountered the same problem as me for a long time.

the error is as follows:
clipboard.png

I know that if I can"t find the code below css, I will not report an error if I delete it, but if I delete it, there will be no style.
is there a big god to help me see how to solve it?

Vux
Mar.10,2021

the original installation used the npm install vux-- save command, and an error was reported because vux.css was missing in the generated file.

is later installed with the vue init airyland/vux2 project command, and the resulting file contains vux.css.
