TypeError: 'type' object is not subscriptable when loading plugins

[Cassius0924]

I'm encountering an issue when trying to run :UpdateRemotePlugins with LunarVim. Here's the error message I'm getting:

Encountered TypeError loading plugin at /root/.local/share/lunarvim/site/pack/lazy/opt/CopilotChat.nvim/rplugin/python3/copilot.py: 'type' object is not subscriptable

remote/host: python3 host registered plugins []
remote/host: generated rplugin manifest: /root/.local/share/lvim/rplugin.vim

It seems like the error is happening when the plugin host tries to import the modules, but I'm not sure why. This error occurs for copilot.py, plugin.py, and utilities.py.

Here are the versions of my dependencies：

Any help in resolving this issue would be greatly appreciated. Thank you!

The tuple[T] syntax only works in Python 3.9 and up.

This is an issue with pynvim.

The tuple[T] syntax only works in Python 3.9 and up.

This is an issue with pynvim.

So is this problem solved and what should I do?

[gptlang]

Is it possible to update to Python 3.9?

[Cassius0924]

Well, thanks for your reply, but I'm not ready to upgrade to Python3.9 yet

These are the lines where the error is occuring:
https://github.com/neovim/pynvim/blob/5f989dfc47d98bba9f98e5ea17bfbe4c995cb0b0/pynvim/plugin/host.py#L29-L40

It uses importlib which is part of the standard library. It should not be erroring. Do you have multiple installations of Python?

[Cassius0924]

I only have Python 2.7 and Python 3.8

[gptlang]

I've opened up an issue on pynvim. I don't Python well enough to resolve this.

[Cassius0924]

Thank you very much for taking this issue seriously 🙏
