My problem seem simple and stupid!
I am not able to install cocoapods. After typing sudo gem install cocoapods ; the terminal prompt me to enter the password. I type ithe admin passwords and it gets rejected. The password is all numbers and the cap key is not on. When I type there is no indication that the numbers I enter are actually being recognized.
I do not expect any help in this stupid situation but I thought I post the question just in case somebody else had a similar issue.
Thanks in advance
