'bundle' command returns a parsing error

Command 'bundle' into rails application returns this error:

'[!] There was an error parsing 'Gemfile': You cannot specify the same gem twice with different version requirements. You specified: sdoc (~> 0.4.0) and sdoc (>= 0). BUndlr cannot continue.

from c:/Users/MacKenzie/Documents/Programming/Projects/odot/Gemfile:16

------------------------------------

# Windows does not include zoneinfo files, so bundle the tzinfo-data gem

gem 'tzinfo-data' platforms: [:mingw, :mswin, :x64_mingw, :jruby}

source 'https://rubygems.org'

-------------------------------------'

Do I need to reinstall a different version of a gem?

Can you post your Gemfile? You can post code blocks/snippets by enclosing them with 3 backticks (the key to the left of the 1 on US keyboards) and blank lines before and after.

```

Note that you have sdoc twice here but you only need one of the two:

gem 'sdoc', '~> 0.4.0', group: :doc

group :doc do
    # bundle exec rake doc:rails generates the API under doc/api.
    gem 'sdoc', require: false
end

Thank you! I after reviewing the video I saw that the group :doc wasn't included and deleted that piece of code.
