I downloaded ROS yesterday, the new full one .. and I had python 2.71 from before ... when I tried roscore tp start using ROS .. I got this error ..


Traceback (most recent call last):
File "/opt/ros/diamondback/ros/bin/roscore", line 34, in <module>
from ros import roslaunch
File "/opt/ros/diamondback/ros/core/roslib/src/ros/__init__.py", line 41, in <module>
import roslib
File "/opt/ros/diamondback/ros/core/roslib/src/roslib/__init__.py", line 50, in <module>
from roslib.launcher import load_manifest
File "/opt/ros/diamondback/ros/core/roslib/src/roslib/launcher.py", line 45, in <module>
import roslib.manifest
File "/opt/ros/diamondback/ros/core/roslib/src/roslib/manifest.py", line 46, in <module>
import roslib.packages
File "/opt/ros/diamondback/ros/core/roslib/src/roslib/packages.py", line 58, in <module>
import roslib.os_detect
File "/opt/ros/diamondback/ros/core/roslib/src/roslib/os_detect.py", line 49, in <module>
import yaml
ImportError: No module named yaml



I guess the problem is with python and the environment variable .. I just don't know how to fix it


thank you :?: :?: :?:
