Build failed: unable to open file (in target '' in project '')(in target '')

问题

I'm trying to open a sample app from Prebid.

When I open the project from the PrebidDemo directory, I receive the error:

I'm attempting to open the project from the PrebidDemo directory: https://github.com/prebid/prebid-mobile-ios/tree/master/example/Swift/PrebidDemo

Sorry for what may be a basic question, I'm new to Swift.

回答1:

It looks like an issue with cocoPods not being installed. If you install cocoPods that should resolve it for you.

回答2:

1. command on your terminal to install it.

   sudo gem install cocoapods-deintegrate
   

2. command on your terminal to install it.

   sudo gem install cocoapods-clean
   

3.Go to your project folder from terminal and type

    pod deintegrate

4. Again

   pod clean
   

5.delete the podfile manually or type in

rm Podfile

Note: make sure you copy all the pod names before deleting

6. follow the same procedure you do to install pod. paste all the pod name and then pod install
