reline | React SVG line icon components | Icon library

The error was caused by an issue with the reline gem in the Ruby 2.7.2 setup. However, if I switch to another Ruby version (2.6.6) using rbenv global 2.6.6 everything seems to work fine.

Here's how I fixed it:

Solution 1:

Since the reline gem comes with Ruby installations, we will uninstall the ruby 2.7.2 version that is the cause of the issue using rbenv :

This is a RubyMine bug. Nothing we can fix on the Cucumber end.

You can either consult a non-recommended monkeypatch / hack. Or downgrade to an early version of Cucumber5.

See https://youtrack.jetbrains.com/issue/RUBY-27294 for more information, including other possible workarounds and a time-frame for the fix from Jetbrains.

You are overwriting the Object#method method. It is never a good idea to overwrite a core Ruby method.

In particular, both IRb and Pry support auto-completion while you type, they support documentation, and many other things. And guess what method they use to get a Method object that they can work with?

So, what is happening is that IRb is calling method(some_method_name) to get access to some method, but you have overwritten the Object#method method with a method that takes no argument.

Don't mess with Ruby's core methods. And if you are using IRb, especially don't mess with core methods that are used by IRb.

There may be one culprit gem here but you will run into this problem again and again unless you fix your underlying approach.

Look at your gems environment; all gems are installed into one folder, regardless of the project you’re working on. So, if you have two projects with conflicting dependencies you will get this problem again.

There are tools, like RVM, which let you create environments for each project. So, each project has its own separate collection of gems and even distinct versions of Ruby if you need 2.7 in one project and 2.5 for another.

See "Easy way to setting Ruby Version Manager (RVM) on projects" for how to use RVM and create a gemset for each project.

Looking at the stacktrace, it's definitely an issue with Bootsnap, and it may have to do with the bleeding edge versions of both ruby (2.6.5 - released Oct 1/19) and rails 6.0.1 (released Nov 1/19).

Seeing this thread as well, I would suggest downgrading your ruby versions into the 2.5 bloodline and trying again and if you're doing a new tutorial, I'm sure that even a modern version of rails like 5.6.2 would work swimmingly as well.

Try RVM or RBenv to install multiple versions/switch between them - it'll make your ruby upgrade/downgrade life quite a bit easier.

Set the top level li's to position: relative; then on the :last-child in the top level menu, set that .sub-menu to right: -2px; to align it with the right side of the parent.
