Django使用问题记录

1.python3下出现问题(首先安装pymysql与mysqlclient)：
django.core.exceptions.ImproperlyConfigured: mysqlclient 1.3.13 or newer is required; you have 0.9.3.
解决方法：
在项目的__init__.py文件中添加如下内容：
import pymysql
pymysql.version_info = (1, 3, 13, "final", 0)
pymysql.install_as_MySQLdb()

2. RuntimeError: cryptography is required for sha256_password or caching_sha2_password
解决方法：
pip install cryptography

3. building 'MySQLdb._mysql' extension

error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual
C++ Build Tools": https://visualstudio.microsoft.com/downloads/
