pycharm运行错误记录

Posted 2023-02-19 智商不够_熬夜来凑

NameError: name '_mysql' is not defined

创建ORM模型时，运行python startapp accounts报错，

 

解决办法：

在setting.py 添加如下代码：

import pymysql
pymysql.install_as_MySQLdb()

 ModuleNotFoundError: No module named 'MySQLdb'

创建ORM模型报错，Did you install mysqlclient?

 

解决办法，安装mysqlclient

pip install mysqlclient

 

TypeError: __init__() got an unexpected keyword argument 'upload_to'
 

创建ORM用户表时，出现的错误提示，错误在在配置图片上传路径：

avatar = models.CharField('用户头像', upload_to='avatar', null=True, blank=True)

类型写错了，更改为

avatar = models.ImageField('用户头像', upload_to='avatar', null=True, blank=True)

再check一下，出现以下错误，根据提示安装Pillow即可

SystemCheckError: System check identified some issues:

ERRORS:
accounts.User.avatar: (fields.E210) Cannot use ImageField because Pillow is not installed.
        HINT: Get Pillow at https://pypi.org/project/Pillow/ or run command "python -m pip install Pillow".

 

RuntimeError: cryptography is required for sha256_password or caching_sha2_password

运行python shell报错，解决办法如下：

 pip3 install cryptography
