Can not perform `pod install` under el capitan (15A279b)

Question

I ran pod install with El Capitan and got this error:

Errno::EPERM - Operation not permitted - /Users/../Pods/Pods.xcodeproj/xcuserdata/root.xcuserdatad

Here's my environment: El Capitan (15A279b), Xcode Version 7.0 (7A220), cocoapod 0.38.2. Any ideas? Thanks!!!

The reason I use xcode7 (and not 6.4) is that I need to target an existing project to iOS9 for testing. And the reason I am using El Capitan is that xcode7 doesn't run under Yosemite. And I need to replace a library (managed by cocoapod) that no longer works under iOS9.

Here's how I install cocoapods in El Capitan sudo gem install -n /usr/local/bin cocoapods as suggested by this link Cannot install cocoa pods after uninstalling, results in error

pod --version

returns

0.38.2

Answer 1

Solution, fix for Cocoapods error on El Capitan 10.11:

sudo gem install -n /usr/local/bin cocoapods

Answer 2

Installing CocoaPods on OS X 10.11

These instructions were tested on all betas and the final release of El Capitan.

Custom GEM_HOME

This is the solution when you are receiving the "Operation not permitted" error.

$ mkdir -p $HOME/Software/ruby
$ export GEM_HOME=$HOME/Software/ruby
$ gem install cocoapods
[...]
1 gem installed
$ export PATH=$PATH:$HOME/Software/ruby/bin
$ pod --version
0.38.2

Answer 3

I had to update the system before 'gem install' otherwise I got this:

ERROR: Error installing cocoapods: activesupport requires Ruby version >= 2.2.2.:

Here's what worked for me:

gem update --system
sudo gem install -V -n /usr/local/bin cocoapods
pod install

I actually needed to just update:

pod update
