Github Pages: Testing for local server

Before committing to github pages, you can upload your homepage locally through ruby and jekyll serve!

Installing Ruby + Devkit & Jekyll

After downloading Ruby, open the ruby prompt and enter gem install jekyll bundler to proceed with the installation.
After completing the installation, check if the installation was successful with jekyll -v.

TrobleShooting

1) Using bundle exec jekyll serve instead of jekyll serve

When I try to run jekyll serve command, sometimes I keep getting bundle errors. In this case, it can be easily solved by using the bundle exec jekyll serve command. It tells you what to do, so just follow the instructions in the Ruby prompt.

A message prompting you to bundle install or bundle update appears saying that bundle is not installed, so you can install it as it is.

but your Gemfile requires i18n 0.9.5. Prepending `bundle exec` to your command may solve this. (Gem::LoadError)

2) Change Gemfile and _config.yml files

If you get a message that your gemfile is a problem, updating Gemfile To solve the problem, you can do one of the two below.

• Comment out the gem to remove(using #)
• Add Gem to the Gemfile, and add it to the plugins: part of the _config.yml file.

3) run chcp 65001 cmd

If you get an Invalid CP949 character "\xE2" error message, this may be an encoding problem on Windows.

If you use UTF-8 encoding, Jekyll will break if a file starts with characters representing a BOM. Therefore, remove this sequence of bytes if it appears at the beginning of your file.
