I am new in IOS development and git. I am having a problem after merging my local repo to the dev repo. After merging when I build the project I get an error in the Xcode that says, **"The sandbox is not in sync with the Podfile.lock. Run 'pod install' or update your CocoaPods installation."**

I searched about this and tried the usual solution reinstalling the pods. But executing 

```
pod install

```

I get another error in terminal that says 

[Terminal Error](https://i.stack.imgur.com/GhsGH.png)

At this point I tried deleting the files associated with the "FTPopOverMenu" pod and reinstalling with *pod install*. The error doesn't go away. Also, I tried solving it in this way - [Error:“The sandbox is not in sync with the Podfile.lock…” after installing RestKit with cocoapods](https://stackoverflow.com/a/22878202/9238916)

But both error in the Xcode and in the terminal still remains. I'm new to IOS and Git. I really don't understand what is really happening here.
