导入错误未定义符号 EVP_MD_size

Question

我的项目需要帮助。目前正在学习本教程 https://charlesleifer.com/blog/encrypted-sqlite-databases-with-python-and-sqlcipher/

在从 python 部分连接到加密的 ddatabase 下，我的树莓派遇到了这个问题，即； ImportError: /home/pi/.local/lib/python3.7/site-packages/pysqlcipher3/_sqlite3.cpython-37m-arm-linux-gnueabihf.so: undefined symbol: EVP_MD_size 我不知道出了什么问题。这是整行代码和错误；

Python 3.7.3 (default, Jan 22 2021, 20:04:44)
