Permission Error in generating python node of examples with ros package #153

Closed pankhurivanjani closed 4 years ago

pankhurivanjani commented 4 years ago

While working with recently released ros package when I try to generate python nodes from visualstates I get the permission error.

pankhuri@pankhuri-LENOVO-IDEAPAD-500-15ISK:~/catkin_ws/src/kobuki_obstacle_avoidance$ rosrun visualstates main.py kobuki_obstacle_avoidance.xml 
Traceback (most recent call last):
  File "/opt/ros/melodic/lib/python2.7/dist-packages/visualstates/gui/visualstates.py", line 331, in generatePythonAction
    generator.generate(self.fileManager.getPath(), self.fileManager.getFileName())
  File "/opt/ros/melodic/lib/python2.7/dist-packages/visualstates/generators/pythonrosgenerator.py", line 42, in generate
    fp = open(projectPath + os.sep + projectName + '.py', 'w')
IOError: [Errno 13] Permission denied: '/.py'
Aborted (core dumped)

Problematic file: line-43_python

Testing with cop node generation also resulted in permission issues:

This error is while working with visualstates melodic ros package. When I did the same stuff using source installation all went well!

Hi @pankhurivanjani

Did you save the XML in your catkin workspace before generating the python node. I think VisualStates doesn't know location of your catkin workspace. Once you save the XML in catkin workspace, it would generate the Python node there.

Yes, it is working fine now. Thanks.
