This does not appear to be an issue with CocoaPods rather with your system unable to install the gem:

ERROR:  Error installing cocoapods:

Please ask in StackOverflow as I can successfully install CocoaPods 1.9.0 on Mojave.

[takep2]

Mojave 10.14.6 used for this problem is a clear installed environment.

[rwgrier]

I get the same error here. Also on Mojave 10.14.6.

[rwgrier]

FWIW, I was just able to install CocoaPods 1.9.0 on Mojave 10.14.6, but I had to upgrade Ruby from 2.3 (whatever was installed) to Ruby 2.6.3.

Could it be that CocoaPods 1.9 requires a higher version of Ruby than what's shipped with Mojave 10.14.6.?

[martin-braun]

Finally I found a recent case to confirm, I have the same issue on Mojave with the same error message. Mojave is still using Ruby 2.3.7p456, so am I. CocoaPods docs suggest to use default Ruby instead of installing a separate Ruby version. So, was Ruby updated in Catalina and Mojave support got dropped? Many people are still stuck on Mojave for compatibility issues, maybe you should bring support to Ruby 2.3.7p456 as well. @dnkoutso

This should be re-opened, I can repro on a clean Mojave. The workaround is to run sudo gem install cocoapods -v 1.8.4.

[swisspol]

Mojave is not some super old OS so it would be beneficial to update the
official installation instructions.

I cannot recall it exactly, but the original reason why I tried to install the latest CocoaPods was I had an Xcode project that was unable to build with the older version of CocoaPods. Don't ask me for details, all I remember was it couldn't resolve references to all Pods, but updating CocoaPods helped, eventually. I still believe CocoaPods should support Mojave a little more instead of suggesting to use an older version of CocoaPods.

Anyways, thanks for clarification.

[LeDominik]

Can confirm exactly this behavior here as well, latest Mojave, never toyed with the Ruby version...ran it to uprade

@dnkoutso --> I honestly believe this deserves to be re-opened _or_ at least document that Mojave users should use 1.8.4

[flatslats]

Same problem on macOS Mojave 10.14.6: sudo gem install cocoapods fails, but sudo gem install cocoapods -v 1.8.4 does work.

[AraibKarim]

xcode-select --install

copy paste the above line in terminal and cocospod will now install with the latest version.

sudo gem install cocoapods

[b-bly]

I agree, this should be reopened. The workaround sudo gem install cocoapods -v 1.8.4 worked, but sudo gem install cocoapods did not.

[f-bone]

dude read the post above you

[uebmaster]

xcode-select --install

copy paste the above line in terminal and cocospod will now install with the latest version.

sudo gem install cocoapods

This works for me

[RealDavid]

sudo gem install cocoapods -n/usr/local/bin -v 1.8.4
USE THIS

[HealthManagerIT]

sudo gem install cocoapods -n/usr/local/bin -v 1.8.4
USE THIS

This works for me
