I am busy changing the world

In Ubuntu 12.04 or newer, edit the ~/.bashrc to add a directory to PATH. Add the following line to the end of the file: export PATH=/my/path:$PATH For the changes to take effect: $ source ~/.bashrc

You will see a blue warning message when starting the LMS or CMS: " p hantomjs not found on path. Set $PHANTOMJS_PATH. Using browser for jasmine tests " It's not something fatal, but I want to get rid of it :D Here is how i did it: 1. Inside the VirtualMachine (vagrant ssh), cd to /opt/edx/edx-platform/node_modules/ and install phantomjs : sudo npm install phantomjs -g phantomjs will be installed inside the node_modules dir. Change permission for the phantomjs dir: sudo chmod 755 phantomjs 2. Include the phantomjs path to your PATH: add this line to the end of ~/.bashrc : export PATH=$PATH:/opt/edx/edx-platform/node_modules/phantomjs/bin eval "$(rbenv init -)" And no more warning / error about phantomjs. Updates July 24, 2013: Pull the latest source code from master and you only need to install the phantomjs, and everything will just be fine: `sudo npm install phantomjs -g `.
