Error when trying to install PyCrypto
Question: I'm using Mac with latest OS X update. I've trying to install PyCrypto over
Terminal but I'm getting error which is shown on image below. The command I
used is `sudo pip install pycrypto`. Can you please help me with this issue?
How do I resolve this? Thanks for your answers.

Here is the error:

    
    
    macfive:Desktop admin$ sudo pip install pycrypto

Error is to big to copy it all. So I just copied the beginning and the end.


Answer: You need to install the Python development files. I think it will work. Try

    
    
    apt-get install autoconf g++ python2.7-dev 
    

Or

    
    
    sudo apt-get install python-dev
    

Either one of the above and then this below one

    
    
    pip install pycrypto
