As a part of the solutions to common issues in Ruby dev environment series, here’s the link to the previous ones:
- Solution: cannot load such file – webrick (LoadError)
- Solution: gem eventmachine fatal error: ‘openssl/ssl.h’ file not found
- Solution: Ignoring GEM because its extensions are not built
Today’s solution will be related to
Unknown ruby interpreter version (do not know how to handle): RUBY_VERSION.
- Ruby environment
Step 1. Find which ruby version you are using.
ruby 3.0.0p0 (2020-12-25 revision 95aff21468) [x86_64-darwin21]
Step 2. On top of your project directory, open Gemfile and replace RUBY_VERSION with the current ruby version that you are running.
Example Gemfile before:
source "https://rubygems.org" ruby RUBY_VERSION
Example Gemfile after:
source "https://rubygems.org" ruby '3.0.0'
Step 3. Close and reopen your Terminal.
