The following worked for me:
this worked for me on Mac
I spent many hours trying to install Jekyll on Mac OS 10.13.4 (High Sierra), I got this error :
The main cause of the build crash is the error below :
After a lot of google searches and a lot of tries nothing solves the issue (trying to install another version of ffi, etc…). Finally I realised that I had a version of Xcode that was not updated because High Sierra is too older to support the lastest version (Thank you Apple…). So I tried to enter the command
gcc -vand I saw this line :That was the problem ! Even If I installed the latest Xcode Command Line Developer Tools, the old gcc provided with Xcode was still used. I entered the command
xcode-select -s /Library/Developer/CommandLineTools/and the commandgcc -vdisplayed the new version :With this version of gcc I could install Jekyll :
I hope this thread could help someone 😉
Try to switch ruby to homebrew version.
brew install rubybrew link --overwrite rubyIf you need to have ruby first in your PATH run:
echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.bash_profileFor compilers to find ruby you may need to set:
export LDFLAGS="-L/usr/local/opt/ruby/lib"export CPPFLAGS="-I/usr/local/opt/ruby/include"For pkg-config to find ruby you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/ruby/lib/pkgconfig"Thanks, @sujaysudheenda! This worked for me on MacOS Catalina:
gem install ffi -v '1.9.18' -- --with-cflags="-Wno-error=implicit-function-declaration"I was having this same issue where I could not install native extensions which would fail when trying to include “ruby/config.h”.
I believe it was because I was using the ruby version installed with Homebrew. After upgrading to a new version of Ruby with Homebrew, I saw the following helpful message from Homebrew
Adding the following lines to my
~/.bash_profilefixed the issue for me:Same problem on Apple M1 while installing cocoapods.
I have tried all of the above solutions but none of them worked for me , please can anyone tell me what’s the real issue…

@ffleming I am seeing all this success using your steps above however I am not one of them 😦
Admittedly I am new to working with Ruby etc and I am hoping that someone here might be able to help me. I am trying to install Jekyll on Catalina (ver 10.15.4) and have Ruby 2.7.0 installed.
When I run “gem install Jekyll” or “gem install --user-install bundler jekyll” (as per the Jekyll site, I get the following:
Am not sure if I am missing some parameters that I need to enter or dependencies missing. Any help for this newbie would be much appreciated.
Thanks in advance.
I’m on Mojave and @ffleming’s solution fixed the issue for me - thanks!
Thanks, @sujaysudheenda 🙌
This worked for me on MacOS Catalina: gem install ffi -v ‘1.9.23’ – --with-cflags=“-Wno-error=implicit-function-declaration”
In our case we install Ruby 2.7 using rvm and update the PATH
Remember compilers and pkg-config:
I hope this can help someone 😃
Has anyone been able to get this to work on an Apple Developer Kit (Silicon) Mac running Big Sur? I’ve tried all of the things above and none of them have worked for me.
Thanks @ffleming ! This worked for me on 10.13.6
@ffleming Likewise works for me on Catalina - thanks a lot, saved me having to downgrade after a couple of hours of searching.
cannot install not ffi nor jekyll on my mac

I am having a similar ffi gem compile error. Has anyone found a solution?
Same error here, though I’m on macOS 10.14.1 Mojave. Trying to
