Invalid active developer path on MAC OS X after installing Ruby

Question

I get this error:

xcrun: error: invalid active developer path (/Applications/Xcode.app), missing xcrun at: /Applications/Xcode.app/usr/bin/xcrun

Answer 1

I started getting the same error after i update macOS Mojave to macOS Catalina.

I just installed few command lines in Terminal,

 1. $ sudo gem install cocoapods
 2. $ sudo xcode-select --install
 3. $ chsh -s /bin/zsh

Then,

Xcode -> Preferences -> Locations -> Command Line Tools and confirm you have current Xcode version selected there.

And it works fine with me. Thanks!!

Answer 2

I started getting the same error after updating to OS X El Capitan.
In my case, all I did was to install it:

sudo xcode-select --install

And it works fine for me.

Answer 3

I too had the same issue after upgrading to OS X EI Captian. I just installed xcode-select using sudo xcode-select --install

Answer 4

For me the solution was as easy as reinstalling Xcode.

It was pointed out here: https://superuser.com/a/981126

You can (re)install Xcode via command line like the answer above suggest, or directly from the App Store.

Answer 5

I resolved the issue with the below steps.

Xcode -> Preferences -> Locations -> Command Line Tools -> Select the command tool matching your Xcode version.
