Error on Login the PC: chruby: unknown Ruby: ruby-1.9

[eqaderi]

This is what I get whenever I login into my ubuntu 20.04:

**

Error found when loading /etc/profile:
chruby: unknown Ruby: ruby-1.9

As a result this session will not be configured correctly.
You should fix this problem as soon as feasible.

After clicking on OK I can use the PC
Also when I type "chruby" into the terminal I get this:

chruby: unknown Ruby: ruby-1.9 jruby-9.2.11.1 ruby-2.6.2 ruby-2.7.1

The second time I type in "chruby" I get this:

jruby-9.2.11.1 ruby-2.6.2 ruby-2.7.1

How do I solve this problem
