Cocoapods:[!] CocoaPods 找不到 pod“Firebase/Storage”的兼容版本：

Question

So I have several pods in my xcode project, which were all working fine. Then I added this 'SideMenu' pod, which told me I need to change the versions of one of my pods, so I did, and now my pods are all messed up. I'm trying to revert to what I had, which is:

platform :ios, '9.0'

target 'Jumper' do
  use_frameworks!

  # Pods for Jumper

  pod 'Firebase/Firestore'
  pod 'Firebase/Storage'
  pod 'FirebaseUI/Storage', '~> 5.0'

end

When I changed my Podfile back to this, and did 'pod install', I am getting this error in my terminal:

[!] CocoaPods could not find compatible versions for pod 
"Firebase/Storage":
In snapshot (Podfile.lock):
Firebase/Storage (= 6.27.0, ~> 6.0)

In Podfile:
Firebase/Storage

FirebaseUI/Storage (~> 5.0) was resolved to 5.2.2, which depends on
  Firebase/Storage (~> 5.0)

I am not sure what the problem is or how to fix it. Any help would be much appreciated

Answer 1

You can try removing the '~> 5.0' part from the pod 'FirebaseUI/Storage', '~> 5.0'. Just keep the pod 'FirebaseUI/Storage'. I hope that should work.

Answer 2

If you really want the old FirebaseUI version, remove Podfile.lock before pod install . Or run pod update instead of pod install .

pod install checks the Podfile.lock to prevent accidental version downgrades.
