I just start learning swift and found I can get a lot of libraries from cocoapods, so I start installing the cocoapods by running sudo gem install cocoapods, however I got the following error during the installation:

I am running macOS Catalina 10.15.2 with Xcode 10.3, not sure is that because of the masOS is outdated, if so is there any way that I can fix the installing issue without updating the macOS?
Same thing happened to me after I erased Macintosh HD from macOS Recovery > Disk Utility and then reinstalled macOS Catalina from macOS Recovery too.
Now, I'm on macOS Catalina 10.15.7 and this error happened when I ran sudo gem install cocoapods.
I'm not sure yet why, but installing cocoapods via Homebrew worked for me.
brew install cocoapods
brew install cocoapods
If you don't have Homebrew yet, run the following on your terminal:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
I'm trying to install gosu on my Mac. I used the command:
sudo gem install gosu
After I enter my password, I get something that says:
Building native extensions. This could take a while...
However, then it comes up with this error:
ERROR: Error installing gosu:
ERROR: Failed to build gem native extension.
Does anyone have any ideas to fix this? I don't know why it would be saying this.
You could try
sudo gem install gosu
if that still does not work, then do the following
- install Homebrew (google it)
- run brew install sdl2.
- run sudo gem install gosu
If that still doesn't work, then try to see if you can get an answer from here
Hope that helps!
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 bought a new Mac this week and have had big problems getting this gem installed. It was never a problem on my old Mac but seems to be particularly difficult on this one.
I have installed libvirt via Homebrew, Xcode4.4 (with command line tools) and gcc4.2. I have symlinked to make gcc4.2 the default compiler.
gem install ruby-libvirt -v '0.4.0' fails because it cannot find the headers
If I pass in the paths to the headers and libraries, like so:
ruby-libvirt -v '0.4.0' -V -- --with-libvirt-include=/usr/local/Cellar/libvirt/0.9.11.3/include/ --with-libvirt-lib=/usr/local/Cellar/libvirt/0.9.11.3/lib/
, it compiles just fine but fails when linking with the following errors:
linking shared-object _libvirt.bundle
ld: library not found for -lruby.1.9.1
collect2: ld returned 1 exit status
make: *** [_libvirt.bundle] Error 1
I have installed Ruby 1.9.3 via RVM and haven't had any troubles installing other native extensions, so I cannot see why it fails to find the ruby libraries in this case.
Does anyone have any ideas? Help would be much appreciated.
I built ruby-libvirt-0.4.0/ext/libvirt by proving external libvirt installed using brew.
Here is what I did to successfully install libvirt.
brew install libvirt
ruby extconf.rb --with-libvirt-include=/usr/local/include/libvirt --with-libvirt-lib=/usr/local/lib/libvirt
gem install ruby-libvirt -v '0.4.0' -V -- --with-libvirt-include=/usr/local/Cellar/libvirt/1.1.4/include/libvirt --with-libvirt-lib=/usr/local/Cellar/libvirt/1.1.4/lib
Hope this helps.
To install the gem you need to install the libvirt libraries. Using 'Homebrew' (a package manager for mac) :
brew install libvirt
bundle install
The exact error you got might have been:
An error occurred while installing ruby-libvirt (0.4.0)
I have finally solved this. It turns out that the command line tools were not properly installed. The following line needs to be added to your .zshrc file (or whatever applies to your choice of shell):
export PATH=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin:/Applications/Xcode.app/Contents/Developer/usr/bin:$PATH
You need only to install libvirt, before the bundle install.
brew install libvirt
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.

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
