cocoapods not installing

Question

What does it mean and how can I fix it:

pod install
/Library/Ruby/Site/2.0.0/rubygems.rb:250:in `find_spec_for_exe': can't find gem cocoapods (>= 0.a) (Gem::GemNotFoundException)
from /Library/Ruby/Site/2.0.0/rubygems.rb:278:in `activate_bin_path'
from /usr/local/bin/pod:22:in `<main>'

Answer 1

Use following commands, and It works for you.

1: sudo gem uninstall cocoapods 

2: sudo gem install -n /usr/local/bin cocoapods

3: pod install 

Answer 2

If you install cocoapod using brew like me

1. Reinstall cocoapods

brew reinstall cocoapods

If you see this error message after you reinstall cocoapods by brew reinstall go to step 2.

already exists. You may want to remove it:
  rm '/usr/local/bin/pod'

To force the link and overwrite all conflicting files:
  brew link --overwrite cocoapods

To list all files that would be deleted:
  brew link --overwrite --dry-run cocoapods

Possible conflicting files are:
/usr/local/bin/pod
/usr/local/bin/xcodeproj

2. To solve conflicting files

brew link --overwrite cocoapods

Hope it helps.

Uninstall the existing cocoapods, if any, by following command:

gem list --local | grep cocoapods | awk '{print $1}' | xargs sudo gem uninstall

Then install it to /usr/local/bin instead of /usr/bin using following command:

sudo gem install -n /usr/local/bin cocoapods

For further query, check this link to uninstall and this link to install cocoapods.

Answer 5

In my case nothing helped, then I:

1. sudo gem uninstall cocoapods
2. cd /Users/nikkov/.rvm/rubies/ruby-2.4.1/lib/ruby; In Finder I searched for cocoapods and removed everything.
3. brew install cocoapods
4. brew link --overwrite cocoapods (if needed)

Answer 6

When I tried @Aamir's solution, I ran into the error:

ERROR: Could not find a valid gem 'cocoapods' (>= 0), here is why: Unable to download data from https://rubygems.org/ - no such name (https://api.rubygems.org/specs.4.8.gz)

This worked for my Mac:

sudo gem uninstall cocoapods
sudo gem install cocoapods
