Question

I am new to python and Pyramid.
I have installed pyramid today and i already have python 2.7.1 pre-installed on my mac machine. I have installed pyramid with the instructions mentioned in the official website. I have used the virtualenv with nositepackages as mentioned in the website and i installed pyramid in my /users/sreekanth directory

After installing i tried my first sample program as mentioned in the docs.

When I try to run the program i am getting an error which is as below.

sreekanths-MacBook-Pro:tasks Sreekanth$ ../bin/python2.7 tasks.py
Traceback (most recent call last):

ImportError: No module named execptions

And also i am not able to import pyramid module from the python shell. Below is the error message i am getting.

sreekanths-MacBook-Pro:bin Sreekanth$ pwd
/Users/Sreekanth/env/bin
sreekanths-MacBook-Pro:bin Sreekanth$ python

Type "help", "copyright", "credits" or "license" for more information.
>>> import pyramid
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named pyramid

Could someone kindly explain me what i am missing and how I can make this work.

Answer 1

The first error indicates you have a typo in your program. Most likely, you wrote

from pyramid.execptions import NotFound

instead of

from pyramid.exceptions import NotFound
#              ^^

And since you’ve installed pylons/pyramid into a virtualenv, you need to activate it first, with source bin/activate in the command line. That will set the correct python path, which you can check by examining sys.path in a python console.
