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

Answer 1

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

pip install robotframework-selenium2library 

Answer 2

I also had a similar problem. I'm running both Python 3.7 and 3.8 because RIDE does not work with 3.8.

I had installed robot framework for Python 3.8 before, and after that I installed everything on 3.7. The problem was fixed when I uninstalled robot framework (and every package related to it) from 3.8 and installed every package on Python 3.7 only.
