Unable to access knife in chef

Question

I am very new to chef, trying to learn it. I have installed chef-client on my system, copied the .pem files and knife.rb file in the chef directory of my chef-repo and now I am trying to access knife but I am getting following error. Can anyone help me out ?

prateek@prateek-desktop:~/mygit/chef-repo/chef$ knife client list -VV
