Selenium import error when running test case with RobotFramework

Question

I'm getting the below error when I'm trying to run a test case in RobotFramework. I installed Selenium2Library but it looks like RF can't find it. Everything works fine with SeleniumLibrary.

Selenium2Library is installed in C:\Python27\lib\site-packages. I uninstalled and installed it a few times to make sure the installation is correct. There were no errors during the installations.

Any ideas where to look for the problem?

Here is the error:

c:\testing>pybot testone.txt

Solution

Resolved the problem by removing Selenium2Library folder and reinstalling it with pip command (which installs all necessary packages).

pip install robotframework-selenium2library
