Error when running ./bin/debci generate-html

[Patience Ankunda <patienceankundat@gmail.com>]

When i run ./bin/debci generate-html i get:

/usr/lib/ruby/2.5.0/rubygems/core_ext/kernel_require.rb:59:in
`require': cannot load such file -- active_record (LoadError)

I reinstalled ruby using  CC=/usr/bin/gcc-6 rbenv install 2.5.1 and
re-run ./bin/debci generate-html and still got the same result.

I have failed to generate the HTML.

How can i go about this?
