我在这里关注 elastAlert 的设置：https ://elastalert.readthedocs.io/en/latest/running_elastalert.html
当我运行命令时python setup.py install --user出现错误error: Could not find suitable distribution for Requirement.parse('cffi>=1.11.5')
所以我试图通过运行来解决这个问题pip install cffi --user
当我运行这个命令时，我得到了输出
Requirement already satisfied: cffi in /usr/local/lib/python2.7/site-packages (1.11.5)
Requirement already satisfied: pycparser in /usr/local/lib/python2.7/site-packages (from cffi) (2.19)
但是当我重新运行时，python setup.py install --user我仍然得到同样的错误：

为什么找不到这个包？
python --version = Python 2.7.10
pip --version = pip 18.1 from /usr/local/lib/python2.7/site-packages/pip (python 2.7)
