Please how can i install gevent & msgpack-python without error?

UPDATE: after i installed several linux tools, the ImportError no longer appeared. It installed some python components and then after that i see the pip install commands worked:

pip install gevent --upgrade

ERROR: gevent 1.4.0 requires cffi>=1.11.5, which is not installed.
Installing collected packages: greenlet, gevent
Successfully installed gevent-1.4.0 greenlet-0.4.15

Python script i am running says: The 'cffi>=1.11.5' distribution was not found and is required by the application

so i ran: pip install cffi

Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    from pip import main
ImportError: cannot import name main

Can anyone please share what was missing component when i got first error and how to fix last error with cffi ?

After "reboot" it started doing something:

pip install cffi

Hello. Are you still having issues? I think that these problems would be helped by checking out #5599 for the issue related to pip update (essentially: use your system's package manager to update pip), and #4861 if there are still issues with ffi.h (though I see some progress was made on this in HelloZeroNet/ZeroNet#2002).

Hi @slrslr. I'll close this issue now, but please let us know if you have any other problems.
