According to Django===2.2.12 from latest upper-constraint.txt, it is not compatible with mysqlclient. Using old version Django===2.1.5 can fix the problem. Could you help me to check the mismatch problem. Many thanks. -- ————————————————————————————— 九州云信息科技有限公司 99CLOUD Inc. 于成德 产品开发部 邮箱(Email): yu.chengde@99cloud.net 手机(Mobile): 13816965096 地址(Addr): 上海市局门路427号1号楼206 Room 206, Bldg 1, No.427 JuMen Road, ShangHai, China 网址(Site): http://www.99cloud.net
