Python.h missing from Ubuntu 12.04
python, ubuntu-12.04
Solution
This should do it:
`sudo apt-get update; sudo apt-get install python-dev -y`
It will install any missing headers. It helped me a lot.
Problem
I installed an openflow controller on my Ubuntu 12.04 called RYU using: ``` sudo pip install ryu ``` I was trying to run a python file using ryu-manager as shown below. ``` sudo ryu-manager simple_switch.py Traceback (most recent call last): File "/usr/local/bin/ryu-manager", line 19, in <module> import gevent ImportError: No module named gevent ``` Then I tried to install gevent using: ``` sudo pip install gevent gcc -pthread -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -fPIC -I/usr/include/python2.7 -c gevent/core.c -o build/temp.linux-x86_64-2.7/gevent/core.o gevent/core.c:4:20: fatal error: Python.h: No such file or directory compilation terminated. error: command 'gcc' failed with exit status 1 ``` What is the cause of this error? I tried to locate `Python.h` using `sudo locate Python.h`, but without success. The output of `python -V` however is ``` Python 2.7.3 ``` Should `Python.h` be there on the system? If so, what should I install to get it?
