[英]Error in importing requests module in python3
我在我的 python 程序中使用請求模塊。 前一天效果很好。 但是現在,在導入 requests 模塊時,它顯示了一個奇怪的錯誤。 它在 python2 版本中運行良好。 但是在python3中顯示錯誤。 我用谷歌搜索但找不到解決方案。 我沒有改變任何東西。 為什么它顯示此錯誤。
這里是:
>>> import requests

AttributeError: cffi library '_openssl' has no function, constant or global variable named 'CRYPTOGRAPHY_PACKAGE_VERSION'
重新安裝cryptography
包將解決此問題。
