Pod setup cannot find cocoapods

Question

After installing cocoapods with sudo gem install cocoapods, attempting to run "pod setup" returns this error:

Could not find 'cocoapods' (>= 0) among 22 total gem(s) (Gem::LoadError)

Output from "pod setup":

/Users/Kevin/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:313:in `to_specs': Could not find 'cocoapods' (>= 0) among 22 total gem(s) (Gem::LoadError)
Checked in 'GEM_PATH=/Users/Kevin/.rvm/gems/ruby-1.9.3-p194:/Users/Kevin/.rvm/gems/ruby-1.9.3-p194@global', execute `gem env` for more information
    from /Users/Kevin/.rvm/rubies/ruby-1.9.3-p194/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:322:in `to_spec'

    from /Users/Kevin/.rvm/rubies/ruby-1.9.3-p194/bin/pod:22:in `<main>'

When I check the directory listed in GEM_PATH, it includes:

...
drwxr-xr-x   5 root   staff   170B Jun 16 23:35 cocoapods-core-0.33.1/
drwxr-xr-x   5 Kevin  staff   170B Jun 16 23:41 cocoapods-downloader-0.6.1/
drwxr-xr-x  15 Kevin  staff   510B Jun 16 23:41 cocoapods-plugins-0.2.0/
drwxr-xr-x  11 Kevin  staff   374B Jun 16 23:41 cocoapods-trunk-0.1.3/
drwxr-xr-x  15 Kevin  staff   510B Jun 16 23:41 cocoapods-try-0.3.0/
...

So the files are there, though its core is root since I used sudo gem install cocoapods.

Solutions suggested on previous Stack Overflow questions that I've tried:

1. Install cocoapods without sudo: Suggested here. However, even following these instructions I get permission denied when trying to use gem install cocoapods.

2. Sudo pod setup: Suggested here. However, pod tells me that I can't use it in sudo.

3. Change permissions for cocoapods files: Suggested here. I tried running the lines provided by the top answer but it says that those files do not exist.

How do I get pod setup to work?

Answer 1

Don't use sudo.

1: sudo gem uninstall cocoapods 

2: gem install cocoapods

3: pod install 

Answer 2

I had the same issue. I solved it by

1. Removing cocoapods
2. Reinstalling it using rvmsudo instead of sudo
rvmsudo gem install cocoapods

Hope it helps!
