CordovaLib missing

If I use ionic platform rm ios and then ionic platform add ios, the CordovaLib folder is missing. I tried updating everything and still have this problem. I had my team member try this on his computer and he has the same problem. What can I do to add ios so that the CordovaLib is included?
