Mic*_*ael 2 python ubuntu ansible
由于paramiko 2.0将其依赖性从pycrypto更改为加密,因此通过pip安装最新的Ansible失败.密码学依赖于cffi,这需要libffi-dev.有谁知道如何解决这一问题？(Ubuntu Trusty 14.04)

要从cryptography >= 1.1pip 安装,您需要安装开发人员包,libffi因为它将包含缺少的头文件.由于您已标记Ubuntu,我假设您正在使用apt包管理器.
apt-get install libffi-dev
您还需要你的发行版中的等价物ssl的开发包,并gcc为cryptography >= 1.1.如果您在系统环境中运行它gcc几乎肯定已经安装,但apt-get install libssl-dev如果缺少它,您可能还需要.
Fedora的/ RHEL等价物libffi-devel和openssl-devel,可与安装dnf或yum根据您的操作系统和版本上.
