Podfile lock errors

[PrabakarMP]

I am programming for sharing an image to a server based on http socket communication. I came across the imageTransfer source and When I run this project, it gives the following error in Xcode.

Diff: /Users/innovationlab/Downloads/ImageTransfer-master/Pods/../Podfile.lock: No such file or directory

Diff: /Users/innovationlab/Downloads/ImageTransfer-master/Pods/Manifest.lock: No such file or directory

The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation.

I heard that I need to run pod install.
So, I tried like below,

1. sudo gem install cocoapods
2. pod setup
3. cd PRAR-Example/
4. pod install
   Here, It throws error as below "Unable to find a specification for CBExtension"
   InnovationLabNewMacMinis-Mac-mini:ImageTransfer-master innovationlab$ pod install
   Analyzing dependencies
   [!] Unable to find a specification for CBExtension.
   InnovationLabNewMacMinis-Mac-mini:ImageTransfer-master innovationlab$

Please what should i do? I have the latest source as it is, downloaded from Github. I need your help urgently please..

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

1. remove your old project
2. clone the new one from github
3. run pod install
4. open the new workspace
5. just run it (cmd + r)
