FireBase Cocoa Pods Installation Not Working

问题

I'm trying to install Firebase via Cocoa Pods for my Objective-C iOS Application. My Podfile is as follows:

target 'RandomName' do

pod 'Firebase/Core'
pod 'Firebase/AdMob'

end

When I run pod install, I get the following error:

[!] Unable to satisfy the following requirements:

- `Firebase/Core` required by `Podfile`

None of your spec sources contain a spec satisfying the dependency: `Firebase/Core`.

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 * out-of-date source repos which you can update with `pod repo update`.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.

The latest version of Cocoa Pods is installed, and I have tried running pod repo update. Having a Podfile of the following works fine, but when I try to @import Firebase; in my AppDelegate.m file, Xcode cannot find the module.

target 'RandomName' do

pod 'Firebase'

end

However, the following combination does not install:

target 'RandomName' do

pod 'Firebase'
pod 'Firebase/AdMob'

end

Any help would be appreciated!

I am having the same problem. Check what version of Firebase is installed when you use pod 'Firebase'. For me it installs 2.4.3 which is an old version. The docs say that the pod should install 3.2. using that pod. It explains why the other pods don't work as they are part of Firebase 3. Pod update doesn't update Firebase to the latest version either. Even forcing a version doesn't work. It can't seem to find the new Firebase versions even though they are in the same podspec.

Here is how I solved it:

make sure you have the latest version of git installed
make sure you have cocoapods >= 1.0.0 installed
delete your pods repo (run pod repo remove master) and use pod setup to make a new one
use the following in your pod file

pod 'Firebase/Auth'

pod 'Firebase/Database'

pod 'Firebase/Core'

(use whatever you want, just don't use 'Firebase')

pod install
everything should install properly

回答2:

Running 'pod repo remove master' to remove the Pods repo //removes the library

Running 'pod setup' //clones the updated git repo for specs which takes long time as its size is beyond 300K (Be patient!)

Running 'pod install' //problem is solved

回答3:

have you tried to add

frameworks use_frameworks!

after target 'RandomName' line

and adding

platform :ios, '9.0'

before target ....

A couple of items to try. From your question, you did try the first two items, but leaving here for completeness of my answer.

The error response you get is helpful. Follow the steps for pod repo update
Make sure your pod is up to date.
```
pwd> pod --version
1.0.0
```
Make certain that your git is up to date. I had a build machine that had an outdated git (1.7), and I had the same exact error

When I updated to this version from git 1.7 it worked fine.

pwd> git --version
git version 2.8.1

My Podfile for using Firebase Dynamic Links
run pod init from the folder where your .xcodeproj is
Be sure to only launch the .xcworkspace instead of the .xcodeproj from here out.

platform :ios, '8.0'
use_frameworks!

target 'the-name-of-target' do
 pod 'Firebase/DynamicLinks'
end

The Same problem occurred while on pod install command.

Please relaunch terminal and navigate to your Xcode project then

simply fire same pod install command. 'Firebase/Database' will installed successfully :)

回答6:

I just doing following step to fix this error:

$pod setup -- verbose

Then do $pod install

that works for me and my pod file is:

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

target 'the-name-of-target' do
 pod 'Eureka', '~> 1.6'
end

UPDATE:

Then you can remove your master and re-install cocoapods using following code:

cd ~/.cocoapods/repos
rm -rf master
pod setup

I had the same error, and my solution was to downgrade Cocoapods to 1.0.0, because Cocoapods 1.0.1 didn't work as I expected. Everything works great now!

sudo gem uninstall cocoapods -v 1.0.1
sudo gem install cocoapods -v 1.0.0

My Podfile:

platform :ios, '8.0'

target 'XXX' do

  pod 'Firebase/Auth'
  pod 'Firebase/Database'

end

回答8:

For people still having problems with this. When directly coping the firebase walkthourgh website, the install string is:

pod `Firebase/Core`

While it should have been:

pod 'Firebase/Core'

No need for pod setup if this applies to you too.

Update Git and Cocoapods to the last version:

Git: $ brew update && brew upgrade

Cocoapods: $ pod repo update
