In my terminal I use:
sudo gem install cocoapods
My terminal gives the error shown below. How can I solve this? I have tried a few variations and I cannot get it to work.
Building native extensions. This could take a while...

Agree with Vinayaka and Bryan you're missing some ruby header files and it looks like they're required. Not sure about your environment setup but it may help to just reinstall the latest Xcode from scratch.
Also, I've had some recent problems with Cocoapods installed via terminal. The terminal installs the latest build of Cocoapods. If you're looking for something stable then maybe try the Cocoapods app. It's clunky and it can't read pod files from the latest version of Cocoapods (so you'll have to regenerate any existing podfiles) but its easier to work with especially for those who prefer a graphical environment.
We need to install Xcode's developer tools. The easiest way to do this is through terminal .
xcode-select --install
Later, if there are any write permission issues, use the below code.
sudo gem install cocoapods -n /usr/local/bin/..
P.S: -n specifies the directory where binaries are located.
Please try with
brew install cocoapods
I finished this tutorial on Medium in order to integrate my Xcode project with SonarQube to have some metrics. Setup SonarQube - Swift. I was able to make it through the last step that is: running fastlane metrics on the terminal while being in the root of the project directory. But I get this error on step "slather".
nokogiri requires Ruby version >= 2.3.0., fastlane finished with errors:
I have also found that someone had a similar question here, but no answers:
Similar Question
If I run:
nicolas$ ruby --version
I get ruby version 2.6.3, which is higher than the required 2.3
ruby 2.6.3p62 (2019-04-16 revision 67580) [universal.x86_64-darwin19]
Does anyone knows how to fix this, or got any hunches? Thanks in advance, I appreciate any help.
After digging around and trying several solutions, I finally solved this. What happened was that I initially installed Fastlane with this command:
brew cask install Fastlane
And it seems that it was using another version of ruby while I had a newer one. So I uninstalled it with:
brew cask uninstall Fastlane
And then I re-installed it with this command:
sudo gem install -n /usr/local/bin fastlane -NV
Because I was having problems with permissions and then all worked good.

I have recently installed swift by following the commands described on https://github.com/PerfectlySoft/PerfectDocs/blob/master/guide/gettingStarted.md
Installation seems to be OK.
swift --version is python-swiftclient 3.2.0
but when go swift build it says "no such command: build"
What am I supposed to do?
"python-swiftclient" has nothing to do with Apple's Swift, it's a library for the OpenStack Object Storage API.
To install Apple's Swift on Ubuntu, you need to follow the instructions detailed at swift.org as told on the Perfect document you're referring: "After you have installed a Swift 3.0 toolchain from Swift.org..."
You will have to install dependencies with:
$ sudo apt-get install clang libicu-dev
then extract the .tar.gz file downloaded from swift.org and set the PATH to the executable - all of this is explained on the site.
Currently running Yosemite and unable to update to ruby 2.1.4 , see below.
Guidos-MacBook-Pro:~ Guido$ rvm install 2.1.4
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.10/x86_64/ruby-2.1.4.
Continuing with compilation. Please read 'rvm help mount' to get more information on binary rubies.
Checking requirements for osx_brew.
/usr/local/bin/brew: /usr/local/Library/brew.rb: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad interpreter: No such file or directory
/usr/local/bin/brew: line 26: /usr/local/Library/brew.rb: Undefined error: 0
ERROR: '/bin' is not writable - it is required for Homebrew, try 'brew doctor' to fix it!
Requirements installation failed with status: 1.
So after I stepped away from the computer for a few hours and came back again, I figured out the issue was that Homebrew was broken after I updated OS to Yosemite. Here is the link http://ryantvenge.com/2014/09/ruby-homebrea-yosemite/ to the solution. If that is not working see commands below.
To fix Homebrew:
cd /System/Library/Frameworks/Ruby.framework/Versions
sudo ln -s Current 1.8
brew update
sudo rm 1.8
To update to ruby 2.1.4:
rvm install 2.1.4
rvm use 2.1.4
I'm working on Michael Hartl's ruby on rails tutorial http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec-development_tools.
I installed Git, updated my OS to 10.8.2 and downloaded XCode 4.5.2.
when I type in
rvm install 1.9.3
this long thing comes up...
Ruby (and needed base gems) for your selection will be installed shortly.
Before it happens, please read and execute the instructions below.
Please use a separate terminal to execute any additional commands.
Notes for Mac OS X 10.8.2, Xcode 4.5.2.
For JRuby: Install the JDK. See http://developer.apple.com/java/download/ # Current Java version "1.6.0_26"
For IronRuby: Install Mono >= 2.6
For Ruby 1.9.3: Install libksba # If using Homebrew, 'brew install libksba'
For Opal: Install Nodejs with NPM. See http://nodejs.org/download/
To use an RVM installed Ruby as default, instead of the system ruby:
rvm install 1.8.7 # installs patch 357: closest supported version
rvm system ; rvm gemset export system.gems ; rvm 1.8.7 ; rvm gemset import system.gems # migrate your gems
rvm alias create default 1.8.7
And reopen your terminal windows.
Xcode and gcc:
Right now Ruby requires gcc to compile, but Xcode 4.2 and later no longer ship with gcc. Instead they ship with llvm-gcc (to which gcc is a symlink) and clang, neither of which are supported for building Ruby. Xcode 4.1 was the last version to ship gcc, which was /usr/bin/gcc-4.2.
Xcode 4.1 and earlier:
- Ruby will build fine.
Xcode 4.2 and later (including Command Line Tools for Xcode):
- If you have gcc-4.2 (and friends) from an earlier Xcode version, Ruby will build fine.
- If you don't have gcc-4.2, you have two options to get it:
* Install apple-gcc42 from Homebrew
* Install osx-gcc-installer
Homebrew:
If you are using Homebrew, you can install the apple-gcc42 and required libraries from homebrew/dupes:
brew update
brew tap homebrew/dupes
brew install autoconf automake apple-gcc42
rvm pkg install openssl
Xcode 4.2+ install or/and Command Line Tools for Xcode is required to provide make and other tools.
osx-gcc-installer:
If you don't use Homebrew, you can download and install osx-gcc-installer: https://github.com/kennethreitz/osx-gcc-installer.
Warning: Installing osx-gcc-installer on top of a recent Xcode is known to cause problems, so you must uninstall Xcode before installing osx-gcc-installer. Afterwards you may install Xcode 4.2+ or Command Line Tools for Xcode if you desire.
** NOTE: Currently, Node.js is having issues building with osx-gcc-installer. The only fix is to install Xcode over osx-gcc-installer.

Originally I had to get homebrew and
brew install libksba
but I did that already and it works. That leads to "Xcode and gcc:" and everything below it.
So, I have homebrew, and the following three commands work:
brew update
brew tap homebrew/dupes
brew install autoconf automake apple-gcc42
But when I try
rvm pkg install openssl
this is what happens
Fetching openssl-1.0.1c.tar.gz to /Users/adamzerner/.rvm/archives

Please note that it's required to reinstall all rubies:

And this is what happens when I try what it says...
Adam-Zerners-MacBook-Pro:~ adamzerner$ rvm reinstall all --force
Adam-Zerners-MacBook-Pro:~ adamzerner$
some other information...
I don't see a .rvm folder under adamzerner, so I can't read what it tells me to (not that I would understand what I'd be reading anyway).
It seems that I have 1.8.7 installed:
Adam-Zerners-MacBook-Pro:~ adamzerner$ ruby -v
ruby 1.8.7 (2012-02-08 patchlevel 358) [universal-darwin12.0]
So... to summarize... when I try to run
rvm install 1.9.3
I get the gcc/Xcode problem. To fix that it says to download apple-gcc42 from Homebrew. When I do that, I get a problem after doing
rvm pkg install openssl
The problem being that I need to reinstall all rubies. When I do that:
rvm reinstall all --force
it seems that nothing happens.
Thanks in advance to anyone willing to help me with this problem!
EDIT: I forgot to say this before. For the "long thing" up above, when I press q to continue, this is what happens...

Adam-Zerners-MacBook-Pro:~ adamzerner$
I've successfully downloaded Ruby 1.9.3 now!
I think the problem was that I hadn't downloaded Command Line Tools from XCode. See http://robots.thoughtbot.com/post/27985816073/the-hitchhikers-guide-to-riding-a-mountain-lion
note that for whoami, it's using the backtick key, which is right above the tab key. It is NOT using quotes.
After I downloaded Command Line Tools, I then typed in rvm install 1.9.3. I got the same "long thing" as before, but at that point I had everything I needed, so I just pressed q to continue, and ruby 1.9.3 was successfully installed!
note: although it was successfully installed, when I typed ruby -v, it still said it was 1.8.7 even though it wasn't. However, after closing and reopening the terminal, it then said that the version was indeed 1.9.3.
