I am trying to start working on some of the website tasks and can't
see to get the
'bundle install' command to work. I have downloaded the EventMachine
project and tried to install that way too.
Here is what I see:
$ bundle install
Fetching gem metadata from <https://rubygems.org/>...........

An error occurred while installing eventmachine (1.2.7), and Bundler
cannot continue.
Make sure that `gem install eventmachine -v '1.2.7' --source
'<https://rubygems.org/>'` succeeds before bundling.
In Gemfile:
jekyll-redirect-from was resolved to 0.15.0, which depends on
jekyll was resolved to 3.8.5, which depends on
em-websocket was resolved to 0.5.1, which depends on
eventmachine
I have tried pulling the EventMachine project and building it my self
but it did not work:
wget
<https://github.com/eventmachine/eventmachine/raw/master/eventmachine.gemspec>
gem build eventmachine.gemspec
sudo gem install eventmachine-1.2.7.gem
