"`pod repo update` does not happen" error in CocoaPods

Question

I download and install CocoaPods from its website, and my pod version is pod --version 1.0.0.

When I want to install Alamofire or swiftJSON, for example, by adding them to my podfile and running pod install

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

target 'random contact' do
  pod 'Alamofire', '~> 3.4'
  pod 'SwiftyJSON'
end

I get this error:

Analyzing dependencies
[!] Unable to satisfy the following requirements:

- `Alamofire (~> 3.4)` required by `Podfile`

None of your spec sources contain a spec satisfying the dependency: `Alamofire (~> 3.4)`.

You have either:
 * out-of-date source repos which you can update with `pod repo update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

Note: as of CocoaPods 1.0, `pod repo update` does not happen on `pod install` by default.

As the error says, I run pod repo update in my Terminal and then it prints this long message:

Updating spec repo `master`
  $ /Applications/CocoaPods.app/Contents/Resources/bundle/bin/git pull --ff-only

[!] CocoaPods was not able to update the `master` repo. If this is an unexpected issue and persists you can inspect it running `pod repo update --verbose`

How can I fix this issue?

Answer 1

You might have a broken Specs repository. Cocoapods suggest you delete your local copies and reclone. Try:

$ sudo rm -fr ~/.cocoapods/repos/master

And then:

$ pod setup

I'd also recommend running:

sudo rm -fr ~/Library/Caches/CocoaPods/

before you run pod setup to clear the cache.
