Python - 没有名为“PyMySQL”的模块

Question

我正在尝试添加“PyMySQL，但它一直在抛出

Traceback (most recent call last):
  File "/home/john/workspace/Python/sql/sql.py", line 1, in <module>
    import PyMySQL
ImportError: No module named 'PyMySQL'

我尝试通过 pip 安装它并再次运行它，但错误并没有消失。关于什么是错误的任何想法？

 john@john-PC:$ sudo pip install PyMySQL

Answer 2

安装“PyMySQL”后，您还需要更新 the _init__.py ，添加 import pymysql pymysql.install_as_MySQLdb() 并将—ba7f0db92b9c88cf18780665ceaf-704.f中的 base.py 替换为pymysql
