Unable to install debase gem

Question

I am trying to debug code in Rubymine. It looks like we need to install debase first. I tried to search in google but could not find any solution.

$ ruby -v
ruby 3.0.0p0 (2020-12-25 revision 95aff21468) [x86_64-darwin20]


$ sudo gem install debase

You are likely using an ancient library or an ancient Ruby version. Add both versions to the question and link to the library's home page. – Lauritz

@D.SM This looks like it's being built on Ruby 3.0.0, so unless you're from the future... – Elysia

Have you tried with Ruby 2.7.2 to see if this a Ruby 3.0 specific quirk? If so, you may want to open an issue for that project. – Elysia

That is probably the reason then. – Lauritz

@Elysia I have tried with ruby 2.6.0 first which did not work. So I upgraded to 3.0.0. But same issue. – Infantine

I used the pre-release gem, and it worked with Ruby 3 gem install debase --pre. Ticket here github.com/ruby-debug/debase/issues/92 – Bandy

Same error as @TechnicalShil mentioned: macOS 11.6, ruby-3.0.0 [ x86_64 ], with RVM use. When installing the pre version, it worked. – Caseose

Answer 1

Debase isn't updated regularly anymore, and RubyMine seems to depend on a fork.

The solution for me was to upgrade RubyMine to the latest version and try debugging again so it can use the latest Debase fork which fixes the error.

Presumptive

Answer 2

Using some extra flags helped in my case gem install debase -v 0.2.4.1 -- --with-cflags=-Wno-error=incompatible-function-pointer-types.
