Unable to find a specification in CocoaPods
IosObjective CRubyCocoapodsIos Problem Overview
I cannot understand why the Cocoapod is unable to find the pod specification I created when I run pod install. Could someone help me solve this trouble?
I'm defining a subspec in my library podspec file like this:
s.subspec 'mysubspec' do |c|
c.dependency 'ABC','1.0.0'
end
This dependency ABC is listed in the library Podfile:
pod 'ABC', :git => '[email protected]:myrepo/Podspecs.git', :branch => 'xyz'
The Podspec file ABC.podspec in the branch xyz of myrepo/Podspecs seems like this:
Pod::Spec.new do |s|
s.name = "ABC"
s.version = "1.0.0"
s.source = { :git => "[email protected]:myrepo/Podspecs.git", :branch => "xyz" }
end
The error is [!] Unable to find a specification for ABC (= 1.0.0)
Solution: import the pod ABC before importing the subspec and add the tag to the podspec.

I suppose that there is a problem with your pod master repo. Delete it and download it again.
You can do:
pod repo remove master
pod setup
pod install
Or:
sudo rm -fr ~/.cocoapods/repos/master
pod setup
pod install

For me it was an issue with finding the spec, not the spec itself. I needed to add a source link to the Podfile, see Podfile documentation
Cocoapods recently added the need to link to the repo that holds the pod spec file you are looking for, the default is:
source 'https://github.com/CocoaPods/Specs.git'
You may need to add multiple source links if you are using more obscure or homemade pods.

Instead of:
s.source = { :git => "[email protected]:myrepo/Podspecs.git", :branch => "xyz" }
Write this: Don't forget the tag...
s.source = { :git => "https://github.com/myrepo/Podspecs.git", :branch => "xyz",
:tag => s.version.to_s }
Solution 4 - Ios
Make sure you added
source 'https://github.com/CocoaPods/Specs.git'
at the very beginning of your Podfile
Solution 5 - Ios
I resolve this after add
source '/Users/username/Documents/path/to/iOS_SpecsRepository'
source 'https://github.com/CocoaPods/Specs.git'
to Podfile. well .I used a local repository as my Repo. So i can user this in another podspec file
s.dependency 'iOS_Networking_CPN', '~> 0.1.1'
iOS_Networking_CPN is in the local path.

With me, this worked like a charm.
pod repo remove master
pod setup
However, you may try directly, pod setup as some users pointed.

I was getting similar error for MGBoxkit
> [!] Unable to find a specification for MGBoxkit
By replacing the following line
pod 'MGBoxkit'
with
pod 'MGBoxKit'
fixed the issue.

Update the master repo for cocoapods.
pod repo update master

You first need to add your Podspec to a private specs repo; this lets CocoaPods find the pod when you try to install it.
Enter the following in Terminal, making sure you’re still in the framework directory you are trying to add:
pod repo add [your framework name] [Your framework Git URL]
pod repo push [your framework name] [your framework .podspec file name]
Solution 10 - Ios
I missed adding , causing issue.
Replacing,
pod 'PodName' '~> 2.3'
With,
pod 'PodName', '~> 2.3'
Did the job.
Solution 11 - Ios
I solved my problem with below command:
cocoa pod update
To update use this command
sudo gem install cocoapods
if above command gives error than use this one
sudo gem install -n /usr/local/bin cocoapods
and than do this
pod repo update

I was working in flutter with all public repos. I was getting a similar error:
Unable to find a specification for `TOCropViewController (~> 2.5.2)` depended upon by `image_cropper`
For some reason TOCropViewController specification was unavailable. I tried the following:
flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec
rm ios/Podfile
flutter run
But the plugin specification was still unavailable. Finally, I solved it by removing the pod's repo master.
pod repo remove master
sudo rm -rf ~/.cocoapods/repos
pod setup
pod install
To validate and confirm that the plugin is here, I tried grep inside .cocoapods, using:
grep -r "TOCropViewController" -n ~/.cocoapods
Inside ~/.cocoapods/repos/trunk/Specs/3/7/4/TOCropViewController/2.5.2/TOCropViewController.podspec.json
I found the plugin's git repo and correct version number.
"source": {
"git": "https://github.com/TimOliver/TOCropViewController.git",
"tag": "2.5.2"
},
After that flutter clean and flutter run started working.

had the same problem.
what really worked for me was gem uninstall cocoapods (as mentioned above by https://stackoverflow.com/users/4264880/seema-sharma) where I found that I had 11 (!) different cocoapods versions installed.
I chose to uninstall all and then gem install cocoapods:1.4.0
All good now.

For me, the below worked well but first try could be direct "pod setup" command If that don't work then go for the below commands would definitely make things happen.
pod repo remove master
pod setup
pod install
Solution 15 - Ios
Follow the below steps :
Step 0: pod repo update master
Step 1: pod install
And you are done!
Solution 16 - Ios
use tis instead. https://stackoverflow.com/questions/45287082/using-private-pod-and-public-pod-in-the-same-project/50618926#50618926
add the souce for both private and public(official) in the beginning of the podfile.
Solution 17 - Ios
None of the answers helped me. Ultimately i figured out that I had a typo spelling mistake for one of the Pods.
Ex:- Firebaseresulrereres/Analytics. It was supposed to be Firebase/Analytics but without my knowledge the pod name had a wrong spelling like Firebaseresulrereres/Analytics.
Correcting the Pod Name did the trick for me!. It cost me 1 hour to find this though!. Development can be ambiguous and frustrating some times! :)
Solution 18 - Ios
pod update
Solved the same error in my case.
