cocoapods not installing

问题

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>'

回答1:

Using following commands, it worked for me.

1: sudo gem uninstall cocoapods 

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

3: pod install

回答2:

If you install cocoapod using brew like me

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

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.

Try sudo gem update

After remove cocoapods
-Install cocoapods

回答5:

In my case nothing helped, then I:

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

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
