gcc错误安装python密码系统centos 7 64

Question

我有一个Centos 7 64位更新。我试图使用以下命令安装python密码学：

 pip install cryptography

但我收到了一条错误消息：

我到处寻找解决方案，但这里没有我的软件包的版本：

Python2.7.5 Python 3.4.5 pip9.0.1来自/usr/lib/python3.4/site-packages (python 3.4)

Answer 1

请执行yum install -y python34-devel，因为您缺少它提供的库。如果您没有这个包，那么您的存储库中可能没有EPEL。用yum install epel-release添加它。
