Solargraph: Latest solargraph can not load when using `parser` gem

[kthibodeaux]

Since updating solargraph it no longer runs, I get the error: uninitialized constant Solargraph::Parser::VERSION (NameError)

I have narrowed it down to only breaking when the parser gem is installed in the current project (either directly in the Gemfile or as a dependency of something else in the gemfile)

I can't reproduce this with a scratch project with parser in the Gemfile.

What versions of Ruby, solargraph, and parser are you using? Are you starting the language server with bundle?

[kthibodeaux]

I am using Ruby 2.6.3, latest solargraph, and latest parser.

I think the issue may be that the projects are run using Docker. The gem folders are in the project directory. Because the gems are in a local directory, and the project uses docker, the system does not have access to those gems, so I do not run things like solargraph with bundle (so the system can use it and run it inside vim).

I have created a basic repo that can be used to reproduce the issue: https://github.com/kthibodeaux/solargraph_bug_demo

The readme has steps to get the error, and steps that show when solargraph is downgraded that it works.

Did you mean?  Solargraph::VERSION

Probably, it's related.
In versions >= 0.39.0 when I start LSP from Emacs I get an error:

Then LSP hangs with

This should be fixed in 0.39.5.

Sorry, turns out there's still a problem with this one, but I'll have it fixed in the next patch release.

[castwide]

Fixed for real in 0.39.6.
