Error: uninitialized constant FFI::Platform::CPU on starting jekyll server

I tried reinstalling Jekyll server and its dependencies, but no luck. Could someone help me to get around this issue? Thanks.

I am using ubuntu=18.04, jekyll=3.8.6

I guess this problem occurs if you've installed Jekyll through apt. In that case a bundle update won't work immediately after an apt remove. Try the following approach:

Uninstall Jekyll first:

sudo apt remove jekyll*

Clean-up your dependency libs:

sudo apt autoremove

Then in your project directory run:

bundle update

Positively, then jekyll serve should work for you.

I ran into the same problem. After running bundle exec jekyll serve --trace, I noticed that some packages were being loaded from the /usr/lib/ruby/vendor_ruby directory. So, I removed the /usr/lib/ruby/vendor_ruby directory (keeping a backup copy of it in my home directory, just in case). This, followed by bundle install, fixed the issue for me.

I was not able to solve this simply by running bundle update or reinstalling jekyll and dependencies with apt as other answers suggested.

What did work was to

  • remove all versions of jekyll and dependencies with sudo gem uninstall ...,
  • remove jekyll and all dependencies with apt-get remove ...,
  • then reinstall jekyll and dependencies with apt-get install ...,
  • and then run bundle update in the project directory.

Then only bundle exec jekyll serve works, and jekyll build still presents the same error.

Try removing Jekyll using apt (if you've installed it that way): 

sudo apt remove jekyll*

Then go to your project, type:

bundle update

and only then:

jekyll serve
