Incompatible with URI >=1.0.0

[swelther]

Today the standard gem URI was released as 1.0.0, introducing a new default parser RFC3986_Parser: https://github.com/ruby/uri/pull/107/files

This results in errors like

NameError: uninitialized constant URI::REGEXP
Did you mean?  Regexp
…/ruby/3.1.0/gems/uri-1.0.0/lib/uri/common.rb:53:in `const_missing'
…/ruby/3.1.0/gems/carrierwave-3.0.7/lib/carrierwave/utilities/uri.rb:7:in `<module:Uri>'

I think I could prevent this error by setting the default parser back to the old one with URI.parser = URI::RFC2396_PARSER. But not sure how carrierwave should behave.

I encountered the same error with uri gem v1.0.0.

Updating to uri gem v1.0.1 resolved the uninitialized constant URI::REGEXP error.
It seems that in uri gem v1.0.1, URI::REGEXP fallback to URI::RFC2396_REGEXP.
