尝试运行的Python行为得到错误

Question

I'm trying to use behave to run selenium tests but I'm stuck at start of that idea. I've setup python, selenium and behave as it should be. I'm running python scripts with selenium without an problem. My problems starts when I try to run them with behave. My python is 3.5.2, selenium is 2.53.2 and behave is 1.2.5. When I try to run any feature file I get errors bellow. It doesn't matter if I try to run it with PyCharm IDE or directly from command prompt. Does any one have a clue what is wrong or what I do wrong?

Errors:

IndentationError: unindent does not match any outer indentation level

Process finished with exit code 1

Answer 1

Your traceback returns: 'IndentationError: unindent does not match any outer indentation level'.

This is usually an indicator that your tab/spaces of your indentation level is incorrect.
Could you try to reformat the file tabbing to 4 spaces?

As khelwood noted, the file you should take a look at is 'features\\environment.py' around line number 11.

This usually should solve this problem.
