Load error: cannot load such file -- webrick

xplosionmind · December 29, 2020, 6:47pm

Hello everybody. After updating to Jekyll 4.2.0, I get the following error, and it seems to have no precedents, here on the forum. Could you be so Kind to help me? (this happens regardless of the website I’m trying to build). Please pardon me if the error is an obvious one but I know nothing about Ruby and Gems…

Everything is up to date (through bundler).

Here’s the log of my build error after entering bundle exec jekyll serve --trace --watch:

a tiny update: it seemed to me from the log that jekyll-admin required some deprecated Gem, but even after removing it, the error seems to be the same. The new log:

There’s a similar sounding issue about Jekyll and Ruby 3.0. Does the work-around mentioned there help?

Alternatively, downgrading to Homebrew’s Ruby@27 might be necessary until all the kinks are worked out.

xplosionmind · December 29, 2020, 9:05pm

The workaround in the issue worked perfectly. Thanks a lot!

kumuditha-udayanga · February 5, 2021, 3:40am

It worked, Thanks a lot!

Ran into the same issue after reinstalling Jelly on an erased Mac, using Ruby 3.0.1.
Solved using:

bundle add webrick

MichaelCurrin · June 1, 2021, 10:06am

I followed the webrick advice here which is covered in a Jekyll GitHub issue linked.

I made a full tutorial for upgrading to Jekyll 3 using this.

I was in same issue cannot load file - webrick. I tried installing different versions of ruby using rbenv and setting the path multiple times. bundle add webrick worked for me. Thanks.

This is the solution. No need to downgrade.
