When I run $ jekyllor $ jekyll serve it raises the following error:
-bash: /usr/local/bin/jekyll: /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby: bad interpreter: No such file or directory
I checked /System/Library/Frameworks/Ruby.framework/Versions/ and Version 2.0 does not exist. It turns out that on the same day I updated on HighSierra, Version 2.3 was installed.
I think Jekyll still looks for Version 2.0. So how can I tell Jekyll to use Ruby 2.3?
Edit:
When I uninstall and then install jekyll, it fails:
$ gem install jekyll

Solution:
I googled can't find header files for ruby and it turned out that "Command Line Tools for Xcode" must be installed which you can download here: https://developer.apple.com/download/more/
However, I have macOS 10.13 and there is no command line tools for Xcode 8.x (which was the latest version I could install). That's why I searched for Xcode in the Mac App Store and installed Xcode 9. Once, it was installed, a window popped up that said "git requires command line tools. Do you want to install it?". I clicked install and still failed to run $gem install jekyll.
Then I tried $ brew doctor. There were some warnings which I fixed one by one and finally I'm able to run $ gem install jekyll.
I had the same issue. I just uninstalled jekyll
gem uninstall jekyll
and then installed it again.
gem install jekyll
Then it worked again.

I'm not able to install json gem on my M1 MacBook. This is the command I'm running.
sudo gem install json -v '2.6.2'
This is the error I'm getting. I'm guessing it because it's picking up Xcode 14.1 Beta 3, but I'm not sure how to have it use a different version of Xcode or if that's the problem.

The issue here is:
Assuming you're trying to install a modern 2.x version of JSON, this error is because it can't see the ruby development tools.
This is because MacOS doesn't include ruby development tools for its base-level version of ruby. That version of ruby is used for some very core-level things on Mac and they lock it down pretty intensely.
The solution is to use rbenv to install a new, user-controlled copy of ruby. This answer has a good step-by-step of how to do that, but the TLDR; is get brew, run brew install rbenv ruby-build, and then run rbenv install 2.6.10 && rbenv global 2.6.10 && rbenv rehash. Then restart your terminal.
Now gem install commands should target the copy of ruby you just installed. (You can validate this by running ruby --version and making sure it lists the version you installed in step 3.) This should fix your issue installing json, whether via gem install or bundle install.

curl -sSL https://get.rvm.io | bash -s stable
close and reopen terminal
rvm install ruby#latest
rvm use ruby-3.0.0 --default
This issue was already reported here, https://github.com/rubygems/bundler/issues/4462.
Can you try bundle update && bundle install.
bundle update will install all of your dependencies, but if you dont want to update all dependencies, try bundle update json only.
So I attempted to install Jekyll on Windows through Cygwin and I encountered an error when I tried to install Jekyll through Cygwin. Here is the output.

I conducted some research online and I wasn't able to find a solution. I tried running Cygwin as an administrator and I still got that error message.
What can I do to fix this issue?
I had the same issue when installing Jekyll and Ruby in the Windows 10 Bash Linux Subsystem. It turned out, that the development package from Ruby was missing. I had to install it first:
sudo apt-get install ruby2.4-dev
In my case. Try to install the dev package in Cygwin package manager, in your case its version 2.3.
Andy
For the record, I encountered the same problem Michael did, and installing the ruby-devel package (using the Cygwin Setup installer) solved my problem. A missing *-devel Cygwin package is a common cause of errors about missing header files.
I am trying to install gem json and getting error for json.
I'm running:

Its a late response, but may it helps someone else. to install json '1.8.3' it requires packages 'libgmp3-dev'.
Use following steps:
sudo apt-get install libgmp3-dev
gem install json -v '1.8.3'
For anyone who has this issue on Sierra, I solved the problem through this thread: https://teamtreehouse.com/community/installing-ruby-on-mac-got-error
Coles notes version is that after updating to most recent version of XCode, I had to accept the terms for the XCode command line tools. See them/agree to them by running:
gcc --version
After I did that, everything installed as expected.
To help you here are some steps to follow in order to install your gem locally:
Download json-1.8.3.
Place the downloaded gem into a folder called gems
Open the Ruby cmd console (click on start button, select Ruby then select "Start command prompt with Ruby")
cd to the gems folder. If the path to the folder is C:\Desktop\gems, write the command: cd C:\Desktop\gems then click "Enter".
To install the gem run the following command:
gem install --local json-1.8.3.gem
I tried it and it worked for me, hopefully it will work for you.
Result:
Second way:
Include the whole path of the gem in the command:
gem install --local C:\Users\kedarl\Desktop\T\json-1.8.2.gem
For me here is the result. (This time with the json-1.8.2.gem):
I've solved this by installing Command Line Tools Xcode of the version I have. I hope this helps someone else.
If you installed Rails through RailsInstaller, try this -

It's a pretty common bug for RailsInstaller currently.
I am trying to install jekyll on a 32 bit windows 7 PC . I downloaded ruby installer-32 bit and 32 bit devkit and extracted un ruby install folder.i got some ssh error which i resolved by temporarily switching to http instead of https and then updated gems as well as installed bundler using
gem install bundler
however gem install jekyll gives following error

You need to install the Ruby DevKit to fix the error you're seeing. Any sane Ruby install has the ability to build stuff on the fly.
I would start with Julian Thilo's awesome instructions for installing Jekyll on Windows:
Run Jekyll on Windows
If you are installing Ruby only for the purpose of running Jekyll, PortableJekyll will give you a full working Jekyll install in < 5 minutes.
Happy Jekylling...
I tried the same thing on 3 systems and found out that installing ruby gems fixed the issue .. so for anyone coming back at this question , this is how you install jekyll on a windows pc:
1.download and install ruby.
2.download devkit extract in to a folder(preferably inside ruby installation dir) and type in cmd window while in your devkit dir :
ruby dk.rb init
ruby dk.rb install
3.download and install gems by
ruby setup.rb
4. finally :
gem install bundler
gem install jekyll
*bundler is a jekyll dependency
I had the same issue on Windows 10 after installing Ruby+Devkit 2.5.X (x64) with the Windows installer.
The reason was that I changed the default path in the installer and had spaces in the path name. Apparently some make scripts do not like that.
Reinstalling to a path without any spaces fixed the issue.
Also see this related issue on github.
I failed to install "gem install jekyll bundler" when ruby was installed in "c:\program files\Ruby26-x64". After I reinstalled ruby on c:\Ruby26-x64 everything went ok. Seems like installation fails to parse path with blank

I have XCode installed (installed it this morning from the AppStore).
Any ideas how I can fix this?
The problem was that XCode 4.3 doesn't in command line tools by default (not sure if this is the first version that doesn't do this). Installing them got it working.
Command Line Tools can be installed by going to Preferences > Downloads > Components.
I'm not sure why your build was failing, but starting with Vagrant 1.0 (not released yet, but RCs are out), the preferred installation method will be packages, so you can just download a pkg for Mac and install, even without XCode installed: http://downloads.vagrantup.com/
