I have such short script:

import pygal
if __name__ == '__main__':bar_chart = pygal.Bar()

and following error: AttributeError: 'module' object has no attribute 'Bar'

Do you have any idea what is wrong? Shall I configure some additional paths? I am using windows.

Thank you

If your script is named pygal.py, when you import pygal, it's going to import your script, not the pygal library you installed into your system site-packages. And your script obviously doesn't have a class named Bar.

The solution is simple: rename your script to something different. Like pygaltest.py or mypygal.py.

And make sure to look at the directory and see if there's a pygal.pyc left behind, which Python compiled from your pygal.py. If so, you have to delete that file.
