Cocoapods: Unable to find a specification for `Firebase/Core`

Question

I have this in podfile:

pod \'Firebase/Core\'
pod \'Firebase/Messaging\'

but getting this error:

[!] Unable to find

Answer 1

If it still doesn't work, remove cocoapods directory rm -rf ~/.cocoapods and re-setup cocoapods using pod setup

Hope that helps

Answer 2

None of the approaches mentioned worked for me. Here is how I made it to work, however:

1. Comment out all of your pods in your Podfile.
2. Comment them back in one-by-one and run pod install after each
3. Clean and run

I hope it will help somebody.

Answer 3

Try to update pod repository

pod repo update

If doesn't help show log from

pod install --verbose

Edit:

try to add

source 'https://github.com/CocoaPods/Specs.git'

to your Podfile. If doesn't help probably there is a problem with your local pod repo. You can fix this using:

pod repo remove master
pod setup
pod install

Answer 4

try to delete the file podfile.lock
it helps with issue:

[!] CocoaPods could not find compatible versions for pod "Firebase/Core":
In snapshot (Podfile.lock):
Firebase/Core (= 4.8.1)

Answer 5

Check if your podfile looks like this and then execute pod install:

platform :ios, '10.0'
use_frameworks!

target '<YOUR APP TARGET>' do

  # Firebase
  pod 'Firebase'
  pod 'Firebase/Core'
  pod 'Firebase/Messaging'

end

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['SWIFT_VERSION'] = '3.0'
    end
  end
end

Answer 6

had the same problem.

what really worked for me was gem uninstall cocoapods where I found that I had 11 (!) cocoapods versions. I chose to uninstall all and then gem install cocoapods:1.4.0

All good now.
