推荐答案

我也发生在OSX 10.6.8，Python 2.6.5上.我认为某些类被动态导入两次.

Also happens for me on OSX 10.6.8, Python 2.6.5. I think some class is getting dynamically imported twice.

尝试更改

from PIL import Image, ImageFont

到

import Image, ImageFont

对我有用.

这篇关于TypeError:参数1必须是ImagingCore，而不是ImagingCore的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
