Liquid Exception: undefined method `tainted?` for 2:Integer

While running Jekyll I was getting the following error, Liquid Exception: undefined method `tainted?’ for 2:Integer

The above issue occured when after a windows re install I had to re install Ruby. The issue seemed like the newer version of Ruby was not compatible with the Jekyll version(4.1.1).

I upgraded the Jekyll version to 4.3.2 and the error disappeared.

That solves the issue. But below I have described how I being a non ruby guy upgraded the Jekyll version. Not sure if that’s the best approach but it worked.

To upgrade I changed the version in Gemfile

gem "jekyll", "~> 4.3.2"

And did

bundle update jekyll

Now this installed both Jekyll 4.1.1 and Jekyll 4.3.2.

Duh!!

So I uninstalled both using

gem uninstall jekyll

And then since a couple of related Gems were also removed, I did a

bundle install

which installed the Jekyll 4.3.2 from the Gemfile.
