Compass watch: undefined method `exists?' for File:Class

Question

(very not familiar with ruby/gem/sass/compass)

I have installed on my Ubuntu server 22.04, ruby 3.2.1, gem 3.4.10, sass 3.7.4 and compass 1.0.3 for a very small project. I followed a tuto to get everyting installed.

But when I run compass watch, I get this issue:

NoMethodError on line ["89"] of $HOME/.asdf/installs/ruby/3.2.1/lib/ruby/gems/3.2.0/gems/compass-1.0.3/lib/compass/configuration/helpers.rb: undefined method `exists?' for File:Class Run with --trace to see the full backtrace

I checked my dear friend Google, but since I'm not familiar with that, I don't know where to look at... That's why I'm here ^^

Any idea to help me to fix this?

Before being on Ubuntu 22.04, I was on 18.04 and it was working like a charm.

Thanks in advance.

Answer 1

• File.exists? and Dir.exists? were removed from Ruby 3.2
• The compass gem hasn't been updated in 9 years and is no longer actively maintained

Whatever tutorial you are following that is telling you to use compass is so incredibly out of date that I do not recommend you continue following it.

If you absolutely must continue using compass then downgrade your version of Ruby from 3.2 to 3.1 or earlier.

You could also try to alias the removed exists? to its corresponding exist? method. – Florri

After deeper search after posted this message, this is what I found... There is no requirement to use compass, there should be an alternative to achieve the same goal (sass/scss => css) Thanks for your help :) – Mariel

I know it's tangential but since it was mentioned, what would replace Compass? I rely on Compass by way of using gulp-compass plugin and I suppose downgrading Ruby to 3.1 is the simplest route. It has just worked for years so we wouldn't have known or thought to be removing/replacing it. – Mariner
