问题描述

每次我在 Python 2.7 上安装 PyopenSSL 和 Scrapy 时，我的软件包安装(使用 PIP 和 Easyinstall)都会失败.操作系统:Win 8.1 64 位.

My package install (using PIP & Easyinstall) fails every time when I install PyopenSSL and Scrapy on Python 2.7. OS: Win 8.1 64 Bit.

目前已解决的问题:

1.Easyinstall和Pip的错误相同
2.将日志更改为详细级别.
3.检查了多个 Stackoverflow 链接，仍然没有运气:

1.The error is same with Easyinstall and Pip
2. Changed the logs to Verbose levels.
3.Checked multiple Stackoverflow links, still no luck:

推荐答案

我遇到了同样的问题.这是我所做的:

I was having the same issue. Here is what i did:

首先使用以下链接在您的计算机上安装 Cryptography:https://cryptography.io/en/latest/installation/#on-windows

Install Cryptography first on your computer, using the following link: https://cryptography.io/en/latest/installation/#on-windows

如果您的计算机上没有安装 openSSL，上面的页面将提供该链接.添加链接中提到的环境变量，然后尝试重新安装.

if you don't have openSSL installed on your computer the above page will have the link for that. Add the environment variables as mentioned in the link and try to install it again.
