您的用戶帳戶不具有的權限，切換到root帳戶。 –

謝謝，但是當我用root帳號安裝這個東西的時候，好像沒有正確安裝。 – DennisShaw

當你說我無法正確運行scrapy時，發生了什麼？運行scrapy時會出現什麼錯誤？ –

相反的pip install Scrapy，做sudo pip install Scrapy

另外，使用virtualenv

@DennisShaw按照[這裏]描述的步驟（https://github.com/scrapy/scrapy/issues/2473），那麼它應該工作。 –

似乎是一個PyOpenSSL問題。

嘗試：

sudo pip install -U pyOpenSSL
