When running srb init in a Rails app I get the following:
Generating /tmp/d20220723-3779490-paqj5l/reflection.rbi with 6784 modules and 142 aliases
Printing your code's symbol table into /tmp/d20220723-3779490-paqj5l/from-source.json
/home/allan/.asdf/installs/ruby/3.1.0/lib/ruby/gems/3.1.0/gems/sorbet-0.5.10206/lib/hidden-definition-finder.rb:123:in `write_constants': Your source can't be read by Sorbet. (RuntimeError)
You can try `find . -type f | xargs -L 1 -t bundle exec srb tc --no-config --isolate-error-code 1000` and hopefully the last file it is processing before it dies is the culprit.
If not, maybe the errors in this file will help: /tmp/d20220723-3779490-paqj5l/from-source.json.err
When I check that error file I find this:
Exception::raise(): Unimplemented Parser Node: EmptyElse
Is there a workaround to get past this error?
Anytime you see Exception::raise in a Sorbet error message, it means there was a bug in Sorbet. You can report Sorbet bugs at https://github.com/sorbet/sorbet/issues
I have created a fix for this bug here: https://github.com/sorbet/sorbet/pull/6161
It will require upgrading Sorbet before you can take advantage of the fix. If you can't wait for that, you will have to hunt down the file in your codebase that uses Ruby's new case ... in syntax for pattern matching with an empty else keyword, and either delete the else keyword or change it to mention else nil instead.
Sorry for the inconvenience.
In the future, please use https://github.com/sorbet/sorbet/issues to report all issues—I only happened to see this by accident today, but I normally do not monitor StackOverflow for bug reports.
