錯誤Python 3.6，WIN10，錯誤安裝pycrpto

Question

我在python 3.6（windows 10）中安裝庫（pycrypto，使用「pip install pycrypto」）時出現問題。我已搜查我的問題和一些答案

說我需要安裝此http://landinghub.visualstudio.com/visual-cpp-build-tools，但它並沒有解決問題，

代碼：

你可能還需要安裝gmp-devel。這爲pycrypto提供了它需要使用libgmp構建的頭文件。在Ubuntu上，我只有libgmp10 installed。當試圖安裝pycrypto時，我遇到了同樣的警告。安裝Ubuntu軟件包libgmp-dev後，警告消失，構建腳本指示它正在使用_fastmath擴展名。

如果您已經安裝了pycrypto而沒有_fastmath，您可以使用-I標誌重新安裝它，例如，

sudo pip install -I pycrypto
