Error occurs during installation of Robot Framework with Python on Windows 7

Question

I have installed "python-3.3.0.msi" successfully and set up PATH as "C:\Python33;" on Windows 7. After that I tried to install Robot Framework by using "robotframework-2.7.7.win32.exe" (double click on the .exe file). At the last step of installation I found the following error:

File "<string>", line 35
    except Exception, err:
                    ^
SyntaxError: invalid syntax

I clicked on "Finish" button --> Installation wizard was disappeared. I set the PATH as "C:\Python33\Scripts". Then I checked the version by using the command "pybot --version" at command prompt. Below error was shown:

Traceback (most recent call last):

How can I solve the above error?

Answer 1

Robot Framework doesn't support Python 3 yet. You should try to use Python 2.7 instead. (Python 3 changes lots of things in the language syntax, including the syntax for catching exceptions shown in this traceback). So, follow the following installation steps:

1. Install Python2.7.3
2. Install robotframework2.7.7
3. set PATH as "C:\Python27\;C:\Python27\Scripts\"
4. Verify the installation by using the command "pybot --version" at command prompt. If everything is OK, the
   following message will be displayed: "Robot Framework 2.7.7 (Python 2.7.3 on win32)"

Answer 2

you should run "pip install robotframework-python3" https://pypi.python.org/pypi/robotframework-python3
