I have installed Pymel on Maya 2009 following the instrucctions given here http://pymel.googlecode.com/svn/docs/install.html

Now whenever I execute the "from pymel import * "
command from the script editor it gives the following error

Error: No module named ply.lex

Traceback (most recent call last):

import ply.lex as lex

ImportError: No module named ply.lex

Can anyone suggest what this is about, and how should I correct it?

This seems to be a simple error. Can anyone please help me out with this?

Search your computer for the folder “ply” it should have the file “lex.py” in it, and probably an “init.py” as well. If those are found, the folder that owns “ply” needs to be in the python path. If not you need ply. Which you can probably download. That or you have a bad install.

looks like setuptools failed to download and install the ply package. you have a few options:

  1. double check your internet connection and firewall settings to ensure that setuptools is working right
  2. delete the pymel egg and reinstall using the manual method describe in the docs
  3. copy the pymel/utils/external/ply directory into your site-packages directory (where the pymel egg is)

I installed pymel again, and the importing error got solved. Now when I type
from pymel import *
it runs without error

But after this command even if I enter a simple command, like
s = polySphere()[0]

It gives the error

Error: name ‘polySphere’ is not defined

Traceback (most recent call last):

File “<maya console>”, line 2, in <module>

NameError: name ‘polySphere’ is not defined

I am using Python 2.5, pymel 1.0.0 and Maya2009. Did the easy install of Pymel and set the enironment variables.

Can anyone plz guess what the problem is

Verify there is not an empty “pymel” directory somewhere in your python path. Then, try not importing it to the global scope, and see what happens.

import pymel

print pymel.polySphere()

same error?

read the what’s new section of the included docs. things have changed since 0.9
