因此,在用戶需要爲Scrapy安裝的許多軟件包中,我認爲我在使用pyOpenSSL時遇到了問題。爲Scrapy安裝軟件包依賴項
當我試圖讓補習Scrapy項目創建,我得到這個輸出如下:

當我用Google搜索的是最後一個錯誤(沒有名爲cryptography.hazmat模塊),我看到一對夫婦提到的pyOpenSSL。所以,我繼續嘗試運行easy_install pyOpenSSL==0.14
,以確保它是最新的版本,但是當我這樣做,我得到這樣的輸出:

所以我有點失落,什麼我需要做的就是Scrapy啓動並正常運行
我有Python的32位安裝以及pyopenssl 32位。不知道還有什麼可能是錯誤的64位... – simplycoding
