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

Question

I got the below error on trying to start Jekyll server

Error: uninitialized constant FFI::Platform::CPU

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

anil@anil:~/customer-churn$ jekyll serve

Answer 1

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.
