我正在尝试运行我的 python 脚本，但出现以下错误。我尝试以不同的方式安装和卸载 psycopg2，但无法正常工作。我的 postgres 版本是 9.6，我的 psycopg2 版本是 2.8.2。有人有同样的问题吗？提前致谢。

ImportError: /usr/lib64/python2.7/site-packages/psycopg2/_psycopg.so: symbol PQencryptPasswordConn version RHPG_10 not defined in file libpq.so.5 with link time reference
最佳答案
我解决了独立安装二进制文件的问题:
pip install psycopg2-binary
关于python - Fedora30 上 libpq.so.5 和 PQencryptPasswordConn 版本 RHPG_10 的问题，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56379922/
