夸脱错误："ImportError:无法从‘h11._headers’导入名称‘Header’“

Question

我想为我的下一个机器人启动一个仪表盘。

但是当我用行导入仪表板模块时

import quart

它会引发一个错误。

我没有找到关于这件事的任何其他帖子。

我在跑

3.8.12

• quart 0.17.0

• quart-discord-any 2.2.1b3

• nextcord 2.0.0a10

有谁能解决这个问题吗？

Answer 1

我已经通过删除Python环境中的h11和h11-0.13.0.dist-info文件夹来解决这个问题(对于您来说，这个目录看起来是/opt/virtualenvs/python3/lib/python3.8/site-packages/)，然后再运行pip install quart。

Answer 2

我通过重新安装h11解决了这个问题。

最新版本h11-0.13.0解决了这个问题。
