conda 运行时给出 RuntimeError: OpenSSL 3.0's Legacy Provider failed to load

Question

我不小心进入了我的miniconda目录并且

rm -r ca*

（只是因为我使用Arch并且在更新miniconda3包时，它说那里有一些证书所以它无法执行更新，所以我删除了它们）
现在每次我运行

conda

命令时，它都会给我 RuntimeError:

OpenSSL 3.0's legacy provider failed to load.

这是完整的日志：

$conda env list

RuntimeError: OpenSSL 3.0's legacy provider failed to load. This is a fatal error by default, but cryptography supports running without legacy algorithms by setting the environment variable CRYPTOGRAPHY_OPENSSL_NO_LEGACY. If you did not expect this error, you have likely made a mistake with your OpenSSL configuration.

During handling of the above exception, another exception occurred:

AttributeError: module 'cryptography.hazmat.backends' has no attribute 'openssl'

我该如何解决这个问题？

Answer 1

我的问题已解决如下：

export CRYPTOGRAPHY_OPENSSL_NO_LEGACY=1
conda install cryptography

仅此而已。
