Could not find gem 'minima (~> 2.0)'

[BourAbdelhadi]

Hello ,

I have an issue with jekyll

I followed these steps :

gem install jekyll bundler
jekyll new blog
cd blog
bundle exec jekyll serve

am getting this error :

Could not find gem 'minima (~> 2.0)' in any of the gem sources listed in your Gemfile. Run bundle install to install missing gems.

After running bundle install , i got this error

The latest bundler is 1.16.0.pre.2, but you are currently running 1.15.4.
To update, run gem install bundler --pre
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your
bundle as root will break this application for all non-root users on this machine.
The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java.

Well , I found the solution , if you have an issue like this : try to install :

gem install minima

&

gem install jekyll-feed

Glad you got it figured out! Looks like a conflict and a problem installing ffi.
