Solution

I’ve searched online and every body says: To fix this issue simply upgrade react-scripts package (check latest version with npm info react-scripts version):

However, this doesn’t work for me.

Finally, I found that just delete the file db.json in your root blog directory, everything goes normal.

Perplexity

I still don’t know why to do this. And I also need to delete the files every time I use hexo s or hexo g. I need to write rm -rf db.json && hexo g every time from now.

If anyone know why to do this and how to simply make hexo not to generate the db.json file, please tell me.
