无法安装Python argon2_cffi

Question

我试图在我的python3.5虚拟环境中安装argon2_cffi，而不使用pip。我已经从github下载了这个软件包。当我想安装这个的时候，

python setup.py构建或安装时，会出现错误。

试试这个解决方案

首先，在激活您的virtualevn之后，使用

pip download argon2-cffi==16.3.0 

运行此命令后，您将得到所有依赖于argon2的文件，它将下载以下文件

argon2_cffi-16.3.0-cp35-cp35m-manylinux1_x86_64.whl,
cffi-1.11.5-cp35-cp35m-manylinux1_x86_64.whl and 
six-1.11.0-py2.py3-none-any.whl

之后只需安装argon2包，只需键入

pip install argon2_cffi-16.3.0-cp35-cp35m-manylinux1_x86_64.whl

它对我有用..。
