Installing PyQuery Via Pip
Question: I'm attempting to install `PyQuery` via `pip` but I'm getting an error I do
not understand. The command I used was:

    
    
    sudo pip install pyquery
    

I get the output below:

I have a feeling it's something to do with dependencies, but should 'pip' not
automatically install dependencies?


Answer: You have missing dependencies. Try running:

`sudo apt-get install libxml2-dev libxslt1-dev python-dev`
