I am trying to installing npm and bundler in a jekeyll dir but I keep getting error and I am pretty sure I messed up a few things. there’s a way to “reset” the development environment?

For npm you can remove the `node_modules` folder. For bundler remove `Gemfile.lock`.  
Then run `npm install` and `bundle install` to reinstall everything in whatever directory you’re working in.

Telling us what exactly the error was will allow us to determine if you need to re-install Ruby or just make some other changes…

I tried to do that by hand and gave up.

There is a Docker Image for that: [https://hub.docker.com/r/jekyll/builder](https://hub.docker.com/r/jekyll/builder).

Also, I built my own on top of it that take a git clone URL and a branch. It git clone the repo with the branch and serves the site on port 4000. This is what I use to render my “staging site” now.
