Code snippet or error message

[andyw8]

Could you please try running this on the terminal and check if it succeeds (from the root of your project):

BUNDLE_GEMFILE=.ruby-lsp/Gemfile bundle

[andyw8]

Also, this is likely encoding related, so it may help if you can share any details about the file encodings used in your codebase.

[vinistock]

@mattn have you been able to get around this issue? It looks like some unexpected encoding is being applied to the pipes used to communicate between the extension and Ruby.

[mattn]

Yes, I solved with removing .ruby-lsp
