Structured Data Linter ruby installation problem

Question

I have a relatively big corpus of structured data, which I need to validate. I am planning to use Ruby Structured Data Linter from this repo https://github.com/structured-data/linter to automate the validation. After cloning the repo and installation of all required packages when I try to run

rake schema:examples

I get an error

C:\Users\anast\Projects\Schema\linter>rake schema:examples
rake aborted!
LoadError: cannot load such file -- rdf/linter
C:/Users/anast/Projects/Schema/linter/Rakefile:3:in `<top (required)>'
(See full trace by running task with --trace)

How can I fix this? It's worth to mention that I already tried to add the lib folder to PATH.

C:\Users\anast\Projects\Schema\linter>gem env

I have absolutely no experience with ruby so would be grateful for any help :)

did you run `rake schema:examples` ? Also can you add to your question what is the output of `gem env` ? — lacostenycoder, Aug 04 '20 at 23:35
yes I tried to run this command, I added more detailed output and `gem env` to the question — gnomus042, Aug 05 '20 at 06:48

You have 2 ruby binary paths in your $PATH variable, but it looks like you need to remove C:\Ruby26\bin

Any ruby script or program which contains a Gemfile you need to install the dependencies by the following steps:

cd into the root of the project and run these commands

gem install rubygems
gem install bundler
bundle install

Then try to run your rake commands again. But also the documentation for this project says to run

bundle install --path vendor/bundler

The instructions on the setup and how to actually run this project are not exactly clear but make sure to check the setup notes section which appear to conflict somewhat with instructions for running locally

I would try both methods after getting your PATH fixed and dependencies installed properly. I'm not on Windows but if you may need to refer to answers to this question for help with that.
