Can any one install on OS X 10.11

Try a lot but still get this error on 10.11

ERROR:  While executing gem ... (Errno::EPERM)
    Operation not permitted - /usr/bin/xcodeproj

what about sudo gem install cocoapods ? There might be some issues with the rootless changes in El Capitan, but I haven't talked to the RG folks about that yet. Anyways, this is purely about rubygems, and isn't a cocoapods issue. You can always use CocoaPods.app in the meantime!

[powhu]

Thank you. I follow this link update ruby for el capital and it work.

I don't want to install home-brew, any other way?

[postmechanical]

Without homebrew there seems to be no other way at the moment. sudo gem install cocoapods results in the same error.

[segiddins]

You can gem install using a GEM_HOME that you can write to. Outside of that, definitely file a radar, since gem install should work by default.

I found out how, and answered here.

@kylebrowning 👏 👏 thanks!

Got it working with @segiddins recommendation by updating my ~/.bash_profile with:

export GEM_HOME=~/.gems
export PATH=$PATH:~/.gems/bin

[rajeshr]

As rootless does not affect /usr/local/bin, the following succeeds:

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

Any caveats?

[nicolastinkl]

Im assuming you're running OS X 10.11.

This is happening because Apple has enabled rootless on the new install.

If you type sudo nvram boot-args="rootless=0"; sudo reboot in terminal.app Your computer will reboot with it disabled.

Once that is done, type

sudo gem install cocoapods -V

the -V is for verbose and will spit out any errors if they happen.

@nicolastinkl Why would you copy and paste verbatim what I already said?

[segiddins]

No, please do not disable rootless just to install a gem.

[kylebrowning]

@segiddins. What?
