Jekyll -v error (Bundler::GemNotFound)

问题:

When running jekyll -v I get the following:

/Users/myusername/.rvm/gems/ruby-2.4.2/gems/bundler-1.16.0/lib/bundler/spec_set.rb:88:in 'block in materialize': Could not find jekyll-feed-0.9.2 in any of the sources (Bundler::GemNotFound)

Update:

After using gem install jekyll-feed I get the following:

回答1:

It seems that you don't have another gem installed, try with this to install it

gem install jekyll-feed

回答2:

You're having a bunch of related issues around dependencies. To make sure it all works itself out, add a Gemfile with the contents:

source "https://rubygems.org"

ruby "2.4.2"

gem 'github-pages' # helpfully pulls in more than just jekyll

and then run bundle. Then when you want to run jekyll, do bundle exec jekyll, and you should be fine.
