Hi, I am a beginner on jekyll. I am following the documentation advice to Build the site on the preview server. Here is what a did : - install the last version of ruby $ruby -v → ruby 2.4.1p111 (2017-03-22 revision 58053) [x86\_64-darwin16] $ gem --version → 2.6.14 - Install Jekyll $gem install jekyll bundler → Version of jekyll : jekyll-3.6.2 When I try to build the site on the preview server (bundle exec jekyll serve) there is the following error : jekyll 3.6.2 | Error: (/Users/admin/Documents/Perso/Site-Internet/Jekyll/inger/\_config.yml): did not find expected key while parsing a block mapping at line 16 column 1 the line 16 is the first line uncommented that shoul be processed. It is this one > title: Inger Hair at Home at Aix en Provence (line 16) I don’t see what can be wrong. Thank you in advance for your answers ---

If I had to guess it’s the parenthesis. Put it in quotes instead so it is treated as a string. ```auto title: "Inger Hair at Home at Aix en Provence (line 16)" ``` ---

Hi mmistakes and thank you for your answer. there isn’t any parenthesis. It was just an information of the line number for this post. And even when I put everything in quotes, I have the same error ---

Can you share your entire \_config.yml file or link to a public repo? YAML can be very unforgiving and there is likely an indent or missing colon or something similar around line 16. ---

Hi mmistakes, I found the solution : there were extra spaces at the exclude line. Now I am facing another issue which is the following When I try to run bundle exec jekyll serve I have an error message which is the following Dependency Error: Yikes! It looks like you don’t have /Users/admin/Documents/Perso/Site-Internet/Jekyll/inger/\_plugins/amp\_filter.rb or one of its dependencies installed. In order to use Jekyll as currently configured, you’ll need to install this gem. The full error message from Ruby is: ‘cannot load such file – nokogiri’ If you run into trouble, you can find helpful resources at [https://jekyllrb.com/help/](https://jekyllrb.com/help/)! (I have the plugin amp\_filter.rb and at the beginning of amp\_filter.rb file, I have the following code require 'nokogiri’ require ‘fastimage’ ) as it says ‘cannot load such file – nokogiri’ So I installed nokogiri MBP-de-Admin:Jekyll admin$ gem install nokogiri Building native extensions. This could take a while… /Users/admin/.rvm/rubies/ruby-2.4.1/lib/ruby/site\_ruby/2.4.0/rubygems/ext/builder.rb:76: warning: Insecure world writable dir /Users/admin in PATH, mode 040777 Successfully installed nokogiri-1.8.1 Parsing documentation for nokogiri-1.8.1 Installing ri documentation for nokogiri-1.8.1 Done installing documentation for nokogiri after 13 seconds 1 gem installed And I have still the same error.

Have you reached out to the Jekyll AMP developer? This is a different issue from the bad YAML in your config file. ---

Instead of adding the plugin .rb files to your `_plugins` folder try removing them. Then install the [gem version of the plugin](https://rubygems.org/gems/amp-jekyll/versions/1.0.2) by adding `gem “amp-jekyll”` to your `Gemfile`. Run `bundle update` then try to build your site with `bundle exec jekyll build`. ---

> [@flamant](#): > > Considering adding gem “amp-jekyll” (and other gems) in Gemfile ,that was what I did at the beginning but none of the gem in Gemfile were running That’s probably because you did not run `bundle install` after… So, the solution involves the following: - Remove `_plugins/` directory - Add `amp-jekyll` to your `Gemfile` ```ruby source "https://rubygems.org" gem "jekyll", "~> 3.6" gem "minima", "~> 2.0" group :jekyll_plugins do gem "amp-jekyll" end ``` - Ensure the current directory in your terminal is the Jekyll project directory - Run `bundle install` - Start jekyll preview server ```auto bundle exec jekyll serve ``` ---

Hi ashmaroll. Thank you very much for your answer. I did what you said and it works. The only gem that I didn’t suceed in loading was “jekyll-ga” ([https://github.com/developmentseed/jekyll-ga](https://github.com/developmentseed/jekyll-ga)). Do you think that putting ``` gem "chronic" # with jekyll-ga # installed gem "google-api-client" # with jekyll-ga # installed ``` will be enough to use “jekyll-ga” ? Another question. I found this ressource page : [https://rubygems.org/gems?letter=J&page=42](https://rubygems.org/gems?letter=J&page=42) Do you think there are all exhaustive gems that I can use in Gemfile ? Finally, how can I grant you “a good answer” ?🙂 ---

Hi again, I don’t see also how to add “jekyll-ideal-image-slider” ([https://github.com/jekylltools/jekyll-ideal-image-slider](https://github.com/jekylltools/jekyll-ideal-image-slider)) ---

Doesn’t look like this plugin has been “gemified”. Meaning you don’t install it with Bundler but rather copy over its `_plugins` folder over into the root of your project. > **[Plugins](https://jekyllrb.com/docs/plugins/)** > > Jekyll has a plugin system with hooks that allow you to create custom generated content specific to your site. You can run custom code for your site without having to modify the Jekyll source itself. ---

Hi mmistakes and thank you for your answer. And what about “jekyll-ga” ? ---

`jekyll-ga` has not been updated for over 4 years now… and from the source-code, it doesn’t look like it will work with Jekyll 3.x series… (Jekyll::Post) had been removed prior to shipping Jekyll 3.0.0
