# Error when trying to run a jekyll project

Dependency Error: Yikes! It looks like you don't have jekyll-commonmark-ghpages 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: 'incompatible library version - /home/koby/gems/gems/commonmarker-0.17.13/lib/commonmarker/commonmarker.so' If you run into trouble, you can find helpful resources at https://jekyllrb.com/help/!

# Step 1:

# Warning! This will uninstall bundler and all other gems

# a removes all versions

# I ignores dependencies

# x includes executables

For Rubygems >= 2.1.0:

gem uninstall -aIx

For Rubygems < 2.1.0:

for i in `gem list --no-versions`; do gem uninstall -aIx $i; done

# If the above didn't work: You could also build out a new Gemfile and run bundle clean --force. This will remove all other gems that aren't included in the new Gemfile.

bundle clean --force

# Step 2:

# Now install the version of bundler required by your project

gem install bundler:2.1.4

# Step 3:

#After this everything should be ok!

bundle install
