Can't install module python pip

Question

i'm new to python. I'd like to use pysnmp module, so i tried to install it with pip but i'm getting errors from it :

Failed building wheel for pycrypto

I tried on multiple system (Ubuntu, Debian and RH) and I always get the same error. How can i install pysnmp ? Or are there any other alternative to work with snmp with python ?

Shell Command :

sudo -H pip install pysnmp

Result :

Answer 1

src/MD2.c:31:20 : fatal error: Python.h : No such file or directory

The actual error is that you do not have the dev files for python language ( python.h not found).

So, install python-dev :

sudo apt-get install  python-dev

Answer 2

Try,

wget https://bootstrap.pypa.io/ez_setup.py

python ez_setup.py

easy_install pysnmp

Answer 3

尝试：

sudo pip install setuptools --upgrade
