如何解决ModuleNotFoundError: No module named 'binance'及导入错误

问题背景 #

• 在Jupyter Notebook执行pip install binance后，导入from binance.client import Client提示ModuleNotFoundError: No module named 'binance'
• 已完成排查：重命名本地binance.py文件，确认未跨Python版本安装，但执行pip uninstall binance时提示该包未安装
• 改用%conda install -c conda-forge python-binance安装后，导入时出现No module named 'importlib.readers'错误，conda list和pip list显示包已正常安装

ModuleNotFoundError: No module named 'importlib.readers'

解决方案 #

• 修复importlib.readers缺失问题：该模块是Python 3.10及以上版本的内置模块，若环境Python版本低于3.10，可二选一操作：
  1. 升级Python到3.10及以上版本
  2. 降级certifi包到兼容旧Python版本的版本：

     pip install certifi==2022.12.07
     

• 彻底重装python-binance：
  1. 卸载所有相关包：

     pip uninstall -y python-binance
     conda uninstall -y python-binance
     

  2. 清理安装缓存：

     pip cache purge
     conda clean --all
     

  3. 用pip重新安装（优先选择pip而非conda，减少依赖冲突）：

     pip install python-binance
     

• 验证Jupyter内核环境：在Notebook中执行以下代码，确认使用的Python路径与安装包的环境一致：

  import sys
  print(sys.executable)
  

  若路径不符，需切换Jupyter内核到对应conda环境。
