I tried all ways and check all topics related to updating to latest revision of ruby on Mac, and not of them works. I started by Pod.init command on terminal, the output was the following:
/usr/local/Library/Homebrew/version.rb:170:in `initialize': Version value must be a string (TypeError)
from /usr/local/Library/Homebrew/os/mac/version.rb:24:in `initialize'
from /usr/local/Library/Homebrew/os/mac.rb:15:in `new'
from /usr/local/Library/Homebrew/os/mac.rb:15:in `version'
from /usr/local/Library/brew.rb:32:in `<main>'
so, by one of the answer was to remove the the cocoa pods and reinstall it again. I uninstall it, but now I am facing issue with the installation.
when I put on terminal sudo gem install cocoapods, is show the following:
ERROR: While executing gem ... (Gem::RemoteFetcher::UnknownHostError)
no such name (https://api.rubygems.org/quick/Marshal.4.8/logger-1.4.4.gemspec.rz)
Any idea how to proceed, any support will be appreciated
This is solved, by using the same commands which I use on terminal but on WRAP. thanks for the developer
