Please could anyone help me with the best step by step instruction to install ruby-Tk on mac OSX catalina 10.15.4 running ruby-2.6.3. doing
gem install tk
gives me this error. "Can't find "tk.h". Can't find proper Tcl/Tk libraries. So, can't make tcltklib.so which is required by Ruby/Tk." Thanks
Below guide assumes you have Xcode already installed. If not install it first from the apple app store.
1) Install ActiveTcl for macOS from https://www.activestate.com
under applications/utilities, there will be a new app wish.app. run this app and if you get the wish console to open, then, it installed ok
2) Using your command line do the following
brew install ruby #this will install latest version of ruby
gem install tk
3) then add other ruby gems that you need for your development environment.
I have tried installing Sass three times on Mac OS Sierra(10.12) from the terminal typing the following code:
sudo gem install sass
Then it asks for my password, I enter it and nothing happens (I even waited half an hour) it does not even gives any error or any other message, then when I try to close the terminal window a message appears saying that the processing will terminate if I close the window.
I already checked on if ruby is installed on my Mac and this is the version I have:
ruby 2.0.0p648 (2015-12-16 revision 53162) [universal.x86_64-darwin16]
What should I do?
NOTE: I'm a newbie and don't know about programming at all and this is the first time I use the terminal.
I had the exact same issue but found a solution for a similar thread on Compass.
You might need to install the developer tools first by entering the following on the command line:
xcode-select --install
Then try
sudo gem install sass
It worked for me and I am now running Sass 3.5.1 (Bleeding Edge)
Buddy,
I just now faced the same problem exactly same.
$ brew install ruby
make sure homebrew is installed on your PC then I did
$ sudo gem install sass
The installation took place
$ sass -v
Sass 3.5.1 (Bleeding Edge)
Hope it helps you too..
I used to have the same problem installing the Sass.
After installing Xcode with
xcode-select --install
I agree the license with
sudo xcodebuild -license
and finally run the app Xcode and finished installing.
After that I write sudo gem install sass and it works.
ERROR: While executing gem ... (Errno::EPERM)

I'm getting a permission error on trying to install Jekyll. I'm currently running OSX 10.11 (El Capitan). I also have Xcode 7 and have installed the developer tools. Is there a workaround or is this an OS specific issue?
This is a side effect of Apple's new rootless (aka System Integrity Protection or SIP) feature in OS X El Capitan, but it does not affect /usr/local/bin.
You might try the following:
sudo gem install -n /usr/local/bin/ jekyll
This tells gem to install Jekyll into a folder that isn't protected by SIP, rather than the default protected location under /Library/Ruby/Gems.
This is the solution suggested by Jekyll's developers.
Apple has added System Integrity Protection (SIP) to increase security. This means that Jekyll has been effected as it uses the default Ruby install.
More details on SIP.
To get around this other users have been installing the Homebrew version. It's also likely that Jekyll v3.0 will start to move towards using this version too.
Install the Xcode command line utilities:
xcode-select --install
Install Homebrew (instructions at http://brew.sh)
Modify $PATH to use Homebrew:
export PATH=/usr/local/bin:$PATH
Modify $PATH for GUI apps:
launchctl setenv PATH "/usr/local/bin:$PATH"
Install the latest Ruby:
brew install ruby
Install the latest Jekyll:
gem install jekyll
Don't install Jekyll with Homebrew, The security of Homebrew is unknown : https://security.stackexchange.com/questions/105088/osx-homebrew-security-risks
Here is how you install it without homeBrew: with a vanilla OSX el cap: http://digitalshore.io/how-to-install-jekyll-mac-os-x-el-capitan/
Update 1:
The only drawback is that you have to type in your password everytime you use sudo, which isnt a big deal. I rather do that than install more dependencies. You should host your Jekyll config on github anyway, that way you wont have to deal with the command line at all. Here is my article on how to set Jekyll up with github: http://stylekit.org/blog/2016/01/06/The-Jekyll-Setup/
Update 2:
Since then i've made a 30 second video tutorial on how you can setup a jekyll blog on github: https://vimeo.com/154566844
It seems this was an OS specific issue. I found a similar issue here, and the answer I found here helped solve the problem :
Cannot install cocoa pods after uninstalling, results in error
I ran into the same error message.
Solved for me by installing ruby from brew.
The new El Capitan version of OS X has a new technology called SIP that won't let users (even when using sudo) write to the /usr/bin folder. This breaks the install process. You can disable SIP, but I'd prefer to keep it on since it provides protection against bad stuff.
SIP does allow writing in the /usr/local folder so what I did was manually install ruby there using brew and then install jekyll. That worked fine.
sudo brew install ruby
sudo nvram boot-args="rootless=0"; sudo reboot
reboot
sudo gem install jekyll -V
cd into directory
jekyll serve --watch
If you cannot get it to work you can always try Cloud9.
Cloud9 offers a full development environment in the cloud (running Linux). Their IDE is also quite good and their environments are also very useful for collaboration. Setting up Git is really simple (using the 'git clone' command). With Cloud9 you will be able to work from any computer with a browser, without installing anything.
create a free account on Cloud9 (https://c9.io)
create an empty project (Ubuntu) and follow these steps:
type on the command line: gem install jekyll
create an empty _config.yml file in the root
create a index.md file in the root
type on the command line: jekyll serve --host $IP --port $PORT --baseurl ''
your website is now running 'locally' on Cloud9
The content of your index.md file:
---
title: Home
---
Hello world!
With Cloud9 you can develop on Linux and feel like a pro. Try it! You will love it.
Try :
sudo su
Enter your password, try again as root gem install jekyll
I'm trying to install Jekyll, a simple, blog-aware, static site generator. When I attempted to run the terminal command gem install jekyll, I got this error:
I then tried to update my RubyGems, using the command sudo gem update --system. That didn't work. Also, I attempted to install using sudo -s (as admin).
Hopefully, I don't have to re-install Ruby. What a headache that would be!
What version of OS X are you using?
Try this from your shell to install xcode command line tools
xcode-select --install
Then launch xcode and agree to the license. Then try again.
I'm having some trouble installing jekyll. Can't quite figure out how to patch the missing link. I think it's an update to Ruby, but RVM is having trouble installing alternate versions of ruby as well.
Heres the full post:
$ sudo gem install jekyll
ERROR: Error installing jekyll:
ERROR: Failed to build gem native extension.
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h

Results logged to /Library/Ruby/Gems/1.8/gems/fast-stemmer-1.0.1/ext/gem_make.out
Does this mean I need to update the version of ruby I'm using via rvm?
Ubuntu
sudo apt-get install ruby-dev
gem install jekyll
Your problem is that either you system doesn't know where make is located at or you don't have it installed. The easiest way to fix this (and probably other issues you'll run into trying to get a ruby system up and running) is to install xcode.
You can get it at http://itunes.apple.com/us/app/xcode/id497799835?ls=1&mt=12 for lion. Or it came on a CD with your computer for earlier versions.
If you're using Lion, please see comments below for a link to how to install developer tools on Lion.
I had the same error on Ubuntu and this helped me sort it out.
You must have ruby-dev installed
apt-get install ruby-dev
If you installed XCode and command line tools are still missing go to Terminal and
xcode-select --install
it will prompt you to install these tools. After that just follow SrBlanco´s answer. That solved the problem for me.
Good luck.
Need to install "make".
I am using Ubuntu 12.10.
sudo apt-get install make
Should work on any Debian based distro.
Note: this problem also occurs on newer MacBook Pro models that come with Mavericks pre-installed. I updated another post with my own solution that didn't involve Xcode at all. My system had the Xcode developer tools installed when I got the machine.
ERROR: Error installing jekyll: ERROR: Failed to build gem native extension
Install Xcode as mentioned if you don't have it installed already (https://developer.apple.com/xcode/). Plus you need the command line tools.
Open Xcode. Go to Preferences > Downloads > Install Command Line Tools
Installing command line tools for Xcode solved the problem for me on my Mac
xcode-select --install.
sudo apt-get install ruby-dev
sudo gem install jekyll
hope this will help, it works with me.
I had this same exact error when trying to install Jekyll, and the following steps from this link helped me. Just in case anyone else comes across this!
http://davidensinger.com/2013/03/installing-jekyll/
I was facing the same issue in my Fedora 22 setup. I had ruby installed but didn't have ruby-devel. Installing ruby-devel fixed the issue for me.
dnf install -y ruby-devel
For older systems:
yum install -y ruby-devel
I followed this on Ubuntu/Linux Mint
sudo apt install build-essential
sudo apt install ruby-dev
sudo gem install jekyll
An addendum: You can install XCode now from the App Store on Mountain Lion. The process is transparent and pretty fast.
I had the same problems with you.
I use Mac OS X 10.9 develop preview version, and I had installed gcc and Xcode.
But my Xcode version is 4.6.
Then I install the Xcode 5.0
After that I type sudo gem install jekyll in the terminal again. Then it works.
Wish it could help someone.
Installing Xcode and going to perferencs > downloads > install commandline tools WORKS!
Same problem on Debian, I had forgot to run this command:
~/.rvm/scripts/rvm
All these answers did NOT work for me.
If you're looking for a solution on ubuntu 14.04, do this:
sudo apt-get install ruby1.9.1-dev zlib1g-dev nodejs
sudo gem install jekyll -v 2.5.3
Unfortunately, nodejs is required because of a bug in Jekyll that enforces existence of runtime JS engine even though it doesn't need one.
For Ubuntu, this helped in my case:
apt-get install libffi-dev
A general advice is to just follow what is displayed as the reason for the error and hopefully you'll be provided with a log file in which the first line suggests which package should be installed, in my case:
To see why this extension failed to compile, please check the mkmf.log which can be found here:
/var/lib/gems/2.3.0/extensions/x86_64-linux/2.3.0/ffi-1.9.21/mkmf.log
MacOS
my solution to this problem
install xcode
type xcode-select --install in the command line
type sudo gem install jekyll in the command line
PS: It is the combination of the two answers in this question.
You are missing the ruby-dev file , just go ahead and run this command - sudo apt-get install ruby-dev
Hope this helps!!
I had the same issue on my macOS(10.14.2), the reason may be:
Apparently with OSX el Capitan, there is a new security function that prevents you from modifying system files called Rootless.
My solution is using rvm:
install ruby on Mac OS X with RVM
gem install jekyll
On windows I have this issue
I actually installed the version rubyinstaller-devkit-2.6.3-1-x64 of ruby
I have removed the ruby completely and Installed the rubyinstaller-devkit-2.5.5-1-x64
and issued the following commands on powershell
gem install bundler
gem install jekyll
and this time no errors where found
I had this issue and of all things, the error was occurring because I hadn't agreed to some updated terms of service in xcode. Running the following did the trick for me. Go figure.
sudo xcodebuild -license accept
For me, I had to upgrade homebrew and install rbenv to the latest ruby version. After that, I followed the instruction at jekyll website. My OS is Catalina 2019, I couldn't install Xcode, which is not compatible yet!
You have to set the path in your .bash_profile to make sure that it initializes the rbenv when you restart your terminal.
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
then
$ rbenv version
2.2.3 (set by /Users/mislav/.rbenv/version)
$ rbenv shell
rbenv: no shell-specific version configured
hope that help!
Here is the (only?) reliable and simple way to install Jekyll on macOS
Install UTM
Install Ubuntu Server
Install Jekyll using Ubuntu instructions at https://jekyllrb.com/docs/installation/ubuntu/
Forward port 22 in the VM settings (22->localhost->22)
Use VS Code on the macOS host
Install Remote SSH
Connect to USER#localhost
Drag and drop the folder on Mac into VS Code (this transfers files to remote)
Enable port forwarding for 4000 (bottom bar on VS Code)
Work on your website
Right click on your website on the file explorer and click download
If you have not done these steps, you might be delighted by:
Ubuntu imports your public SSH key from GitHub
VS Code magically handles file transfer in and out
VS Code magically installs your VS Code extensions onto the remote server and allows file search on the remote host
