Can you attach a sample project please?

[Tonshell]

[dnkoutso]

Please upgrade to CocoaPods 1.3.1 also and if you can upload a sample project. Screenshot is not particularly helpful.

I am going to close this.Will re-open if a proper sample project is attached which demonstrates the issue. Also make sure to update to CocoaPods 1.3.1.

Hi Tonshell
I was also facing same problem since last three days, but its solution is pretty easy which Finally I configured within 5 minutes.
lets move towards the solution.
Step 1. Open your Terminal.
and you are in your default users's Directory.

Step 2. just write following command to update or install your pod
[sudo] gem install cocoapods

if that above command does not works, no needs to worry about, because you will be having sudo less gem in your mac machine.

So after that try this command.

gem install cocoapods --user-install

this will install or updates latest version of pod in your current Users directory smoothly

Remember, NO needs to step into or step out of any directory when you open your terminal very first time, because you'll be in your default user's directory very first time you open your terminal,
Otherwise if you stepped in our stepped out any directory just close your terminal and reopen and to repeat step number 2.

Step 3. Now move to your required project's directory and to install pod while using following command
pod init

and after adding your required dependencies to your pod install it while using following command

pod install

please leave your comment if it works out....

I was getting the same error. So I updated the cocoa Pods to 1.4.0 version. It worked.

[segiddins]

gem install xcodeproj

[pintokit]

Running bundle update will install the correct version of the xcodeproj gem dependency.

@infinZero i met a same question,and solve it with your solution,thanks.

[AmLearning]

that did the trick!

[DatHT]

I had the same problem in Xcode 9.4.
I fixed it by just update to the newest cocoa pods.

[brx-usman]

gem install xcodeproj

Worked perfectly..

[mubashar26]

I solved it by following method:
Step1: update your gems by this command "sudo gem update"
Step2: after successful updating the gem, install the pods by this command "pod install".

Hope fully it will fix your issues.
