I’m following these instructions:[Jekyll on Windows](https://jekyllrb.com/docs/windows/#installation-via-rubyinstaller)

Everything went well except I get the following message:

> **ERROR: Error installing jekyll:**  
> \*\* The ‘http\_parser.rb’ native gem requires installed build tools.\*\*

Even with this message it seems that Jekyll installed because when I ran the cmd: jekyll -v I get a response of: **jekyll 3.5.1**

So I assume all went well and I can ignore the error mentioned above?

Right?

did you try it and see if it works? Jekyll requires lots of gems and those gems require other gems sometimes.

I can’t remember if I had to install the build tools or not. I just did the ruby installer that matched my OS I think (Win 10).
