无法导入电视节目

Question

有电视节目使用我的代码。出于某种原因，我的代码在一段时间后不再工作，所以尝试升级 telethon 库。现在连telethon都导入不了

按照此处的安装说明进行操作：https://telethon.readthedocs.io/en/latest/basic/installation.html

# pip3 show telethon

Name: Telethon
Version: 1.8.0
Summary: Full-featured Telegram client library for Python 3
Home-page: https://github.com/LonamiWebs/Telethon
Author: Lonami Exo
Author-email: totufals@hotmail.com

Location: /home/XXX/.local/lib/python3.5/site-packages
Requires: pyaes, rsa
Required-by:

在此之后，尝试对 telethon 库进行基本导入失败。运行 python 3.5.2

# python3 -c "import telethon;"

Traceback (most recent call last):

Answer 1

这是您正在使用的 python 版本中的错误（参见 https://github.com/python/typing/issues/266); and it's also an open issue in Telethon repo (see https://github.com/LonamiWebs/Telethon/issues/1177）。

将您的 python 升级到最新版本，问题就会消失。
