我需要安裝“quandl”。 但是當我在終端輸入“sudo pip install quandl”時，我收到以下錯誤：

然后我嘗試在終端中使用“sudo pip install cryptography”手動安裝“cryptography”。 然后我收到以下錯誤：

我查看了許多網站，閱讀了很多文章，仍然無法擺脫這個錯誤。 我是“quandl”和機器學習的新手。 所以我很感激安裝“quandl”的任何詳細方法。

運行：

pip install quandl

沒有sudo工作。 請參閱Qandl 文檔 。 運行sudo pip是針對Python社區和提到的壞習慣這里的米克Ohtamaa。 使用sudo將導致Root重寫普通用戶不再具有寫權限的包數據。
