If you're trying to require a shard:
- Did you remember to run `shards install`?
- Did you make sure you're running the compiler in the same directory as your shard.yml?```

@baelter Thank you for report this, I'll try to reproduce it :+1:

Have you tried scry as well? :sweat_smile: See: https://github.com/crystal-lang-tools/scry/ and https://github.com/crystal-lang-tools/vscode-crystal-lang/wiki/Settings#server

[baelter]

No yet. But I will if that is what's getting most developer attention.

Hi @baelter Do you still have this issue? I'm trying to reproduce it :sweat_smile:

I am having the same issue right now (macOS 10.14.6)

[pavestru]

Also tested scry (followed installation instructions). Having this one line in main.cr

puts "Hello"

scry gave me this error

Fixed by https://github.com/crystal-lang-tools/vscode-crystal-lang/commit/f3667c88203bcc4b79145dc5fc50f1434d47a2a0

I'm having this issue on debian-buster, ubuntu and when using crystal-docker-image.

I can see that the issue is solved by f3667c8, I actually cloned master and built the extension and it works fine.

I'm just wondering why it hasn't been published to the vscode marketplace? ^^

This fix has been published for some time.
