PyJWT 不会导入 jwt.algorithms （ModuleNotFoundError：没有名为“jwt.algorithms”的模块）

Question

由于某种原因，PyJTW 似乎无法在 Ubuntu 16.04 上的 virtualenv 上运行，但它在我的本地 Windows 计算机上运行良好（也在 venv 内）。我一无所知，我尝试了不同的版本，复制了与我在 Windows 机器上完全相同的版本，但我仍然无法让它工作。

我正在运行Python 3.7.7。

Answer 1

您不必注册“RSAAlgorithm”。您也安装了“加密技术”：

PyJWT==2.3.0
cryptography==36.0.1

那么你可以直接使用“RS256”算法而无需注册：

import jwt
jwt.encode(payload, private_key, algorithm="RS256")

Answer 2

我遇到过同样的问题。该错误似乎是pyjwt和jwt模块之间的冲突（如上面@vimalloc 所提到的）。对我有用的是运行以下命令（注意：我使用的是 Python 3.6.10）。

pip3 install -U pyjwt
