cffi python 包不匹配的错误版本

Question

我正在尝试安装 python 软件 (https://github.com/GuLinux/AstroPhoto-Plus)，但在日志中，我在安装后执行期间遇到此错误：

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：

我正在尝试安装 1.14.6 版本

重新安装和同样的错误：

 Exception: Version mismatch: this is the 'cffi' package version 1.14.6, located in '/tmp/pip-build-env-34pknb8l/overlay/lib/python3.8/site-packages/cffi/api.py'.

The two versions should be equal; check your installation.

我不是 python 开发人员，尽管我在 github 中发布了一个问题，但我没有答案（似乎存储库已被放弃一年），我没有知道我能做什么。

谢谢。

通过安装包“python3-cffi”解决了

sudo apt install python3-cffi

并降级 pip 包：

pip install --upgrade cffi==1.14.0
