python - DigitalOcean 中 Pyopenssl 的密码学构建失败是什么意思？

问题描述

我试图在 Digital Ocean Ubuntu 16.04 服务器中安装 pyopenssl 模块。我收到此错误最后失败的密码学构建轮，然后是一些错误。

    ----------------------------------------

这个问题在做的时候也出现了pip3 install cryptography，但是当我用这个命令添加所有依赖项时它就消失了 -

sudo apt-get install python-pip python-dev libffi-dev libssl-dev libxml2-dev libxslt1-dev libjpeg8-dev zlib1g-dev

我在这里缺少什么。

标签： pythonpython-3.xpip

解决方案

设法以某种方式弄清楚自己。

apt-get install python3.6-dev为我做的。

虽然我这样做了sudo apt-get install python3-dev，但由于某种原因，问题仍然存在。

感谢 Hatshepsut在“pip install cryptography”期间缺少 pyconfig.h 中的评论
