cffi python包版本不匹配时出错
cffi python包版本不匹配时出错
提问于 2021-07-30 13:58:45
我正在尝试安装一个python软件(https://github.com/GuLinux/AstroPhoto-Plus)，但是在日志中，我在安装之后的执行过程中得到了这个错误：
Exception: Version mismatch: this is the 'cffi' package version 1.14.6, located in '/tmp/pip-build-env-kuxyuc2x/overlay/lib/python3.8/site-packages/cffi/api.py'.
When we import the top-level '_cffi_backend' extension module, we get version 1.14.0, located in '/usr/lib/python3/dist-packages/_cffi_backend.cpython-38-arm-linux-gnueabihf.so'. The two versions should be equal; check your installation.据我所知，我有：

The two versions should be equal; check your installation.我不是python开发人员，尽管我在github上发布了一个问题，但我没有答案(似乎存储库被sinde遗弃了一年)，我不知道我能做什么。
谢谢。
