# Solve error when executing Jekyll using GitHubPages Version

There are some issues when running Jekyll in different version of supported by GitHub Pages.

There are some issues when running Jekyll in different version of supported by Github Pages.

## First Problem: cannot run locally

According to the GitHub Pages’ Dependencies Version, the supported Jekyll version for GitHub Pages is 3.9.0. However, the Hydejack PRO Theme was using a 4.1 version, which is incompatible with GitHub.

It was necessary to downgrade the Jekyll version. In order to do so, the Gemfile was changed, as below:

gem "jekyll", "~> 3.9.0"


When trying to run locally, the following error started to happen:

Invalid US-ASCII character "\\xE2


## The solution: Set proper environment variables

In my particular situation (Arch Linux), it was necessary to add the following environment variables:

export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
export LANGUAGE=en_US.UTF-8


In order to the locale ‘en_US.UTF-8’ to be propery set in these ENV variables, it must already be set into the system. Use locale -a to verify. If the locale is not on the list, it must be set:

• uncomment the line en_US.UTF-8 UTF-8 in the /etc/locale.gen file
• run locale-gen to add it
• set the system locale in /etc/locale.conf to LANG=en_US.UTF-8 as well

After that, when running:

./bundle exec jekyll serve


It worked properly.

## Another issue: cannot run remotely

It’s now working perfectly locally, but for some reason it was not working on GitHub. The strange behavior was: the pages were blank. No errors, response HTTP Status Code=200 - but blank.

I added TravisCI to be able to see the internal erros - and no errors were found after compile at this point, but the pages were still not rendered properly. If I hit /blog/, the HTTP Status code was 200, but the page was blank. If I hit the main page (/), it only showed the text that I set in index.md file, but no other information was rendered.

## The solution: stop using themes on GitHub Pages

I suspected that the problem was related to the local theme #jekyll-theme-hydejack directory (because I changed to the “remote_theme: hydecorp/hydejack@v9” in _config.yml file and it worked - however, using a non-PRO remote theme). I believed that, for some reason, Github was denying the use of #jekyll-theme-hydejack as a gem.

After getting some help from LazyRen on the issue 170, I was able to make it work.

In the end, the theme: attribute seems not to work in GitHub pages, and, instead of using it, it was removed and the necessary content from theme directory was them moved to the repository root directory.

In summary, I had to perform the following actions for Hydejack PRO 9.0.4 to work on GitHub Pages:

• _config.yaml file:
• remove the attributes #theme: jekyll-theme-hydejack and #remote_theme: hydecorp/hydejack@v9 (ssems not to work with GitHub Pages)
• Gemfile file:
• change the jekyll version from ~> 4.1 to ~> 3.9.0 (to be compatible with https://pages.github.com/versions/)
• remove the line gem "jekyll-theme-hydejack", path: "./#jekyll-theme-hydejack" (it is unnecessary, since the theme is no longer used as a referenced gem file)
• #jekyll-theme-hydejack directory:
• move the following subdirectories to the root of the repository:
• _layouts
• _includes
• _sass
• assets
• jekyll-theme-hydejack.gemspec file
• change rake version to ~> 12.3.3 (GitHub pointed previous version as security vulnerability)
