Can't get CocoaPods working - ruby

Question

I installed CocoaPods and it says Successfully installed cocoapods-0.33.1, but whatever I would try to do with pod command, like pod install, I get the following console output:
Max$ pod install

I am using Mac OS 10.10 (Yosemite beta version) and Xcode 6.0 beta2, but I think back when I used Mavericks and Xcode 5.1.1 I had the same problem.

Answer 1

I finally solved my problem.
Short answer:
I had to install ruby 2.1.2, then reinstall cocoapods and everything worked.
Long answer:
Resolve all warnings from brew doctor;
remove unused libraries;
remove MacPorts;
resolve additional warnings which I already do not remember;
I might even reinstalled brew.
Install rvm;
Install & use ruby 2.1.2 using rvm;
rvm requirements complains about many missing packages, install them;
among them, there is gcc46, which I was unable to install. After Xcode 4.2 or something, command line tools come without gcc. So if rvm requirements does not find one, it suggests gcc46. But the point is, installing brew install apple-gcc42 solves the problem. rvm requirements stops complaining and you can install ruby 2.1.2:
rvm install 2.1.2;
rvm use 2.1.2;
Install cocoapods, as suggested in #Varsha Vijayvargiya's answer.
I might forgot something, so if you have any questions - ask. Here are some links which helped me:
update mac osx to 10.10 and pod cannot work;
Installing Ruby 2.0.0 with RVM and Homebrew on Mac OS X 10.8 Mountain Lion;
Homebrew GCC won't install on OS X 10.10 Yosemite with Xcode 6;
Installing gcc on Mavericks.

Answer 2

-- Open Xcode 6
-- Open Preferences
-- click on Locations tab
-- Change the Command Line Tools version to Xcode 6.0
-- Uninstall cocoapods
$ sudo gem uninstall cocoapods
-- Install xcodeproj
$ sudo gem install xcodeproj
-- Install cocoapods
$ sudo gem install cocoapods
-- Run pod.

Answer 3

You most probably missed a step, but it's not your fault.
sudo gem install cocoapods
pod setup <–- this is not specified by the doc even though it's vital
pod install

Answer 4

See https://github.com/CocoaPods/CocoaPods/issues/2219
Or check that if you have multi ruby versions in your system:rbenv versions, and try rbenv global 1.9.x to change your ruby version for installing.

First warning says that you've insecure permissions for your bin directory:

OK

Answer 6

First warning says that you've insecure permissions for your bin directory:
warning: Insecure world writable dir /usr/local/bin in PATH, mode 040777
See: warning: Insecure world writable dir /usr/local/bin in PATH, mode 040777
You can fix it via (you need root credentials):
sudo chmod go-w /usr/local/bin
The error 'require': cannot load such file indicates that you some missing or broken gem package. You can probably fix it by re-installing cocoapods:
gem uninstall cocoapods # Follow by sudo if necessary
gem install cocoapods --verbose # Follow by sudo if necessary
And make sure that your xcodeproj is present:
gem install xcodeproj --verbose # Follow by sudo if necessary

Answer 7

my experience: I had the same error after upgrading to Yosemite, I just did a "gem update" and it worked.
