I’ve been using Think Python to learn programming over the last few days. Today I got to chapter 4 when it starts talking about needing Swampy, a package (correct term?) used to teach, in this chapter, interface design.
So, getting to my issue, the first bit of code I’m told to enter is
from swampy.TurtleWorld import * world = TurtleWorld() bob = Turtle() wait_for_user()
When I run it, I get the following error
Traceback (most recent call last): File "/Users/dylanevans/Documents/Code/Python/TurtleWorld.py", line 1, in <module> from swampy.TurtleWorld import * ImportError: No module named swampy.TurtleWorld
I have installed and uninstalled swampy using pip and distutils, swampy is in site-packages and when I ask the interpreter what modules are installed, swampy shows up. I just don’t see why I’m getting the error.
Also, my PYTHONPATH has ‘/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/swampy’ at the end. Although it does have it twice, I don’t know whether that’s important.
Any help would be greatly appreciated.
Open up a terminal and type
env | grep ^PYTHONPATH hopefully you get something like this:
Select one of the paths you have write access to and that will be
If no such PYTHONPATH exists we will make our own in our home directory and ensure python can see it in future:
mkdir ~/.ourPyPkgPath echo 'export PYTHONPATH=$PYTHONPATH:~/.ourPyPkgPath' >> ~/.profile
And in this case we will use
Now to install swampy
easy_install -d $OURPYPKGPATH 'http://pypi.python.org/packages/source/s/swampy/swampy-2.1.1.tar.gz'
Now it should be just a case of either
source ~/.profile or logging out and in again, in order to set the PYTHONPATH environmental variable.
