When I try to install Chromium I get this error message: "chromium: /usr/bin/chromedriver exists in filesystem"
I installed the "chromdriver 2.1" package before (pacaur -S chromedriver), because I use the Watir-Webdriver Ruby gem, and it is a dependency. What can I do to use Chromium with "chromedriver" package installed?

You don't need chromedriver. Ruby gems installed with the gem utility do not care for the actual packages as long as the required files are present. And since the chromium package provides its own /usr/bin/chromedriver, this shouldn't be a problem. And if you've installed the gem from AUR, chromedriver is not listed as a dependency either. I've just checked and been able to install the specified gem with chromium present in the system, and thus you may safely remove chromedriver.
