[英]Devstack installation error : CryptographyDeprecationwarning: int_from_bytes is deprecated, use int.from_bytes instead
Hello I am trying to install devstack on ubuntu 20.04 and I keep getting error您好,我正在尝试在 ubuntu 20.04 上安装 devstack,但我一直收到错误消息
Cryptographydepricationwarning: int_from_bytes is deprecated use int.from_bytes instead Cryptographydepricationwarning:int_from_bytes 已弃用,请改用 int.from_bytes
Does anyone knows how to solve it?有谁知道如何解决它?
Thanks in advance提前致谢
you need to pin an older version of cryptography, eg cryptography<3.4, that will satisfy SecretStorage's dependency and not throw deprecation warnings.您需要固定旧版本的密码学,例如 cryptography<3.4,它将满足 SecretStorage 的依赖性并且不会抛出弃用警告。 That means you should install cryptography<3.4 into your environment, and this version of cryptography should be picked up.
这意味着您应该将 cryptography<3.4 安装到您的环境中,并且应该选择此版本的 cryptography。
To Do so:为此:
pip freeze | grep "cryptography" #show current version of cryptography
sudo pip uninstall cryptography #uninstall it
sudo pip install cryptography==3.3 #install new version <3.4 (here I chose 3.3)
