Ruby罗盘-无法加载此类文件-罗盘/核心（LoadError）

Question

I'm trying to install and work around compass gem and the commands I used while installing this are -

gem install sass
gem install compass

Now I can see the version of sass with the command -

sass --version

But when I do -

compass --version

The messsage i get is -

/home/name/.rbenv/versions/2.3.1/lib/ruby/site_ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- compass/core (LoadError)

from /home/name/.rbenv/versions/2.3.1/bin/compass:22:in `load'
from /home/name/.rbenv/versions/2.3.1/bin/compass:22:in `<main>'

I've tried searching on google and went through whole lot of github issues and stackoverflow questions regarding compass, but any of those didn't help.

How should i resolve this issue?

Update:- I was asked to include the o/p of following command here -

gem list -d | grep compass -A 4

    Speed up your Sass compilation by making @import only import each

Ruby compass is no longer supported. Best get off. But I ran into the same issue, only one one VM, a linux machine with ruby 2.6.2p47 & gem 3.0.3, until finally I saw that gem install compass was not getting compass-core. Whereas on other versions it was getting it. Solution - do it explicitly:

gem install compass-core

Anyway - it worked for me and I hope it helps other stragglers!
