With the stable version of cocoapods, I get a different error:

CocoaPods 0.38.0.beta.1 is available.
To update use: `sudo gem install cocoapods --pre`
[!] This is a test version we'd love you to try.

[segiddins]

@intelliot as detailed in the CHANGELOG (https://github.com/CocoaPods/CocoaPods/releases/tag/0.38.0.beta.1), the object passed to the Podfile post-install hook has changed.

[intelliot]

How can I fix this error? I couldn't find any mention of Installer or Hooks in my git repo.

[segiddins]

you probably just want to change project to pods_project

[intelliot]

Cool - that fixed the first error - but now even cocoapods 0.38.0.beta.1 gives me this error:

run gem install xcodeproj and pod install again ;)

[Benuuu]

@segiddins @mrackwitz is there a reason the project property wasn't deprecated?

Right now I'm testing 0.38.0.beta1 before making my team upgrade, but I have to maintain a separate Podfile because of this change.

[mrackwitz]

@Benuuu: The reason for that is that we made a major conceptual change in how we provide access for advanced users to hook into the installation process, as documented in #3648. We could get rid of the whole proxy layer, which was out of sync, and is now even more with the changed introduced in the last minor release. It would have cost a lot effort to provide that in a backwards-compatible manner. Sorry for you personally for the inconvenience at this place. Sometimes we need to make hard decision and get rid of "debt" to continue moving forward.

Good that you were able to find a workaround solution for now. I wanted to write a section for the release blog post on how to migrate and map prior used calls to the new API to make it easier, seems like in this special case it would been helpful to have that earlier in place.

[intelliot]

Don't know if this is the right thing to do, but after using the beta, I had to add this to my Gemfile in order to get the previous version of CocoaPods to work again:

gem 'xcodeproj', '~>0.24.3'

[siuying]

I had same problem upgrading to 0.38.0.beta.2

My hook:

post_install do |installer|
  # Disable "Application Extension API Only" flag in pods
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['APPLICATION_EXTENSION_API_ONLY'] = false
    end
  end
end

It now failed with error:

I have a quick glance on the xcodeproj API, build_settings should still work as before?

[segiddins]

@siuying that's an issue with Xcodeproj, please open up an issue over there

[siuying]

@segiddins Thanks, will do.

[changpianji]

@segiddins
you probably just want to change project to pods_project
could u pls explain this for more details? i am really frustrated about (undefined method `project' for #Pod::Installer:0x007f9be5906fe0 this problem

[segiddins]

@changpianji change where you call the project method to use the pods_project method instead.

[stevelaw]

@siuying Have you resolved the issue you last posted? I am getting the same error.

[siuying]

@stevelaw the issue is tracked at https://github.com/CocoaPods/Xcodeproj/issues/286, I'm currently pinned at older version

[apcro]

@changpianji change where you call the project method to use the pods_project method instead.

For those still not sure what to do (not being familiar with Ruby, cocoapods or Xcode), change the installer.project.targets.each line in your _podfile_ in xcode to install.pods_project.targets.each

This worked for me.

[rockylive]

sudo xcode-select -r fixed the issue

[gistya]

Changing to pods_project fixes, but then I get build_configurations failure. cocoapods is totally broken right now, kind of sad.

[lituanhui77]

@intelliot l have changed project to pods_project.pod install again,find [!] Failed to find 'Pods-MasonryTestsLoader-Masonry' target.how should l do?

[intelliot]

@lituanhui77 I'm not encountering this issue any longer, and don't know what you should do. Maybe try creating a new issue.

[lugearma]

My problem was when I installed a new version of Xcode, and when I did pod install always the console get me back
Generating Pods project [1] 6472 abort pod install
Then I did gem install xcodeproj and I tried again and It worked

[hemantbavle1]

I keep getting this error, everything was working fine, suddenly this started showing up on pod install.
I am using xcode 8.3.2, on MacOS Sierra 10.12.4. I had to branch my project in for unique feature sets. But all was working fine till this morning. Not sure what's happening here.
