在Processing ./1/bcrypt-3.1.7.tar.gz时失败是时因为building 时出错。

5、解决方法

使用apk list 查看已安装的包

https://cryptography.io/en/latest/installation.html

Alpine中安装

sudo apk add gcc musl-dev python-dev libffi-dev openssl-dev libressl-dev

If you get an error with openssl-dev you may have to use libressl-dev.

但还是报相同的错。

cryptography 3.3.1 requires cffi>=1.12, but you'll have cffi 1.10.0 which is incompatible.
