我正在尝试安装 python 软件（https://github.com/GuLinux/Ast roPhoto-Plus），但在日志中，安装后执行期间出现此错误：
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.
据我了解，我有：
