Something wrong in your LSP.sublime-settings possibly. Feel free to post it.

All packages are reporting errors that seem to be a dependency problem

[husanjun]

I noticed that sublime_lib has just been upgraded, I don't know if that's why

[rchl]

Not sure. It works here with the latest sublime_lib version.
But I'm on Mac.

[jfcherng]

It failed on my side too after I manually update sublime_lib to https://github.com/SublimeText/sublime_lib/releases/tag/v1.5.1

---

Manually rollbacked to v1.5.0.

[husanjun]

I looked at the source code for sublime_lib

I deleted the local dependency typing, LSP worked normally, but after restarting ST, typing was installed automatically, and the problem appeared again

[rchl]

The typing dependency must come from some other package and that is probably the main reason why it breaks.

Well, maybe not the main but at least part of the problem.

Yes, there is no Collection in typing with py33 (which means https://github.com/packagecontrol/typing/blob/v3.7.4/st3/typing.py#L1830 won't be True)... hence the error.

What is typing.__file__ ?

The typing dependency must come from some other package and that is probably the main reason why it breaks.

Does that mean LSP doesn't work if users have any other package installed which use the typing dependency?

By the way, why does LSP come with its own "implementation" of typing, instead of using the dependency from Package Control?

[rchl]

I might be wrong because I didn't study its code carefully but it seems like the typing dependency doesn't fall back to native typing when available (only does that for some stuff like collections). That causes issues when using LSP since those are not the same types as the native ones so there are type conflicts.

Stay sublime_lib v1.5.0 it is also working

[jfcherng]

sublime_lib v1.5.2 is fine in my local test.

[husanjun]

sublime_lib v1.5.2 is fine in my local test.

Thank you. I'll close it

Mypy types were first used on August 27, 2017: 875f54c

The first commit of the PC typing module was in 2018: packagecontrol/typing@0849c8c

The plugin/core/typing.py file was first created at the beginning of 2020: 9a009d6

LSP could perhaps make use of the PC typing module, but I think we can skip that step once we have migrated to python 3.8: #1389
