Hi all, it’s my first post! Hi! I have 2 issues with jekyll. First is when I run jekyll build I get this error ```auto /Users/monica/.rvm/gems/ruby-2.6.3/gems/ffi-1.11.3/lib/ffi.rb:6:in `require': incompatible library version - /Users/monica/.rvm/gems/ruby-2.6.3/gems/ffi-1.11.3/lib/ffi_c.bundle (LoadError) ``` this is my $PATH var for reference ```auto /Users/monica/.gem/ruby/2.6.0/bin:/usr/local/opt/ruby/bin:/Users/monica/.rvm/gems/ruby-2.6.3/bin:/Users/monica/.rvm/gems/ruby-2.6.3@global/bin:/Users/monica/.rvm/rubies/ruby-2.6.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/monica/.rvm/bin:/Users/monica/.rvm/bin ``` The second is that Jekyll is not loading in my template theme (self-created), but that might be solved with fixing the first main problem. Please help, SOS. -Monica ---

no idea about first one (site still builds ok?) If your theme is not loading that sounds like a css issue, if you use the Inspector in Chrome and go to the Console tab are that errors? Is there a link to the repo/site? fairly common to use GH pages for a project repo but not set the baseurl in the config file to the repo name. ---

Hi rdyar, No I can’t actually build locally anymore, but on Github pages it works. > **[mgnica/mgnica.github.io](https://github.com/mgnica/mgnica.github.io)** > > personal site.

what OS? how did you install jekyll? what do you get if you run `jekyll --version` sort seems like not everything it needs is installed, try `gem install jekyll` again maybe? ---

MacOS Mojave 10.14.6 I get the same error if I run `jekyll --version` I tried `gem install jekyll` and reran `jekyll --version` and got the same error. ---

maybe try: gem install ffi you could also try running `rvm gemset empty` followed by `gem install bundler` and `bundle install` but I am just copying and pasting this off the interweb, I don’t know much about ruby at all. ---

I actually realized it never worked on this computer, only on my work computer which is same OS. I diffed the paths and there are some missing on this current computer. That’s probably the error. I’ll also try `gem install ffi`. Edit: `gem install ffi` totally worked! niicceee As for the css, no I’m not seeing any errors, but I did notice that the * * * layout: starspace title: mgnica’s webpage : D * * * is surrounded by quotes which I don’t think are supposed to be there. Edit: yeah, please help me get my theme working. The links are all correct it’s just giving a 404 for some reason. ---

correct - the front matter is always at the top of the page so move: ```auto --- layout: starspace title: mgnica's webpage :D --- ``` up to the top. Your `assets/css/styles.css` should be called `styles.scss` - it is not importing the main.scss file because a css file cannot do that, needs to be named .scss, when jekyll runs it will process the scss and rename it to .css. I think I also saw a couple other path issues but not sure. Somewhere I saw a path as `assets/abc..` when it should be `/assets/abc...` - it was missing the leading /. ---

Hi rdyar, Thank you - it’s all set up and it looks a lot better now 🙂 Does jekyll always have index.html in root and index.html in \_site? I am getting confused over that. Actually, in general I’m getting confused on where to create and put new pages for my site. For example, I want to add piquant.html under \_site but it doesn’t seem to like that. And sometimes my image links break without me doing anything to them. Edit: OK, everything in \_site is generated by jekyll. Why does my javascript get constantly written over whenever I modify it? I’m not sure where else to modify the javascript. It’s ruining the actually built Github page too ---

> [@monica](#): > > everything in \_site is generated by jekyll correct, the entire contents of \_site get deleted and then rebuild every time jekyll runs, so you never edit anything in there. If you have JS then just put it in a assets/js folder or where ever you want it (in the root), and it will be copied to that same location in the \_site folder when jekyll runs. ---

and you generally should not have the \_site folder on GH - you should ignore it in Git and delete it. Editing something in the \_site folder on GH is not going to do anything, GH is making its own version of your \_site folder from your source and serving that. ---

I had the exact same issue that Monica faced, and “gem install ffi” totally worked!!! Thanks Monica for raising and thanks rdyar for the solution.
