objective c - CocoaPods Errors on Project Build

Question

I'm unable to build a project that uses CocoaPods. I get the following errors:

diff: /../Podfile.lock: No such file or directory
diff: Manifest.lock: No such file or directory error: 
The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation.`

$ pod install seems to work fine and adds a Pods Project to my Workspace. I've tried $ pod update but this doesn't help.

It seems that PODS_ROOT is not being set.

Podfile:

platform :ios, '6.0'

workspace 'Example.xcworkspace'
xcodeproj 'example/Example.xcodeproj' 

pod 'TestFlightSDK', '~> 1.3.0-beta.5'
pod 'TestFlightLogger', '~> 0.0.2'
pod 'CocoaLumberjack', '~> 1.6.2'
pod 'Reachability', '~> 3.1.0'
pod 'SBJson', '~> 3.2'
pod 'MKMapViewZoom', '~> 1.0.0'

Answer 1

I had a similar problem when I did major changes to my Podfile. My solution was to remove the workspace file and run pod install again:

rm -rf MyProject.xcworkspace
pod install
