I try to use Xvfb to make the headless code run. However, I encountered the problem that "Xvfb not found on your system" when I tried to run my ruby code. Then I tried to install Xvfb using
sudo apt-get install xvfb
However, "apt-get: command not found" is showed. Thus, I have not idea what should be installed to avoid the original Xvfb error. Any helps? Thank you.
Answer
Old question, but found it will trying to find the apt-get commands. The command not found is likely because you are not on a debian system. So you should probably be using yum.
