Hi,

Moving this to Jekyll Talk from jekyll github issues: [https://github.com/jekyll/jekyll/issues/5873#issuecomment-278823777](https://github.com/jekyll/jekyll/issues/5873#issuecomment-278823777)

I’m just getting started with Jekyll, taking over website/app deployments from the developers.

As far as I can tell, I have successfully installed Jekyll. When I run `jekyll --version` in Terminal, I get `jekyll 3.4.0.`

When I run `jekyll build` on my repo, however, I get the following output:

```

I did try DirtyF’s suggestion of installing jekyll with homebrew and [this gist](https://gist.github.com/DirtyF/5d2bde5c682101b7b5d90708ad333bf3), but so far have gotten the same errors.

Any help with this would be greatly appreciated.

Hey Francis,

Im actually on holidays so typing this on my iphone before i hit the beach. The following is off the top of my head.

Try deleting your gemfile.lock and running `bundle update`.

Preview your jekyll website with `bundle exec jekyll serve`

I would use homebrew to install ruby. Latest version is ruby 2.4  
`brew install ruby`

Also this could be your issue. You need to add ‘bundle exec’ before the command ‘jekyll build’ like so  
`bundle exec jekyll build`
