Cannot start with "ModuleNotFoundError" after installing with "pip install esbonio[lsp]"

[yaegassy]

Reproduction Procedure (prepare)

mkdir -p /tmp/esbonio-check
cd /tmp/esbonio-check
python3 -m venv venv
source venv/bin/activate
pip install -U esbonio[lsp]

Error

(venv) esbonio-check$ python3 -m esbonio --help
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/runpy.py", line 197, in _run_module_as_main
    return _run_code(code, main_globals, None,

    from pygls.features import COMPLETION, INITIALIZE, INITIALIZED, TEXT_DOCUMENT_DID_SAVE
ModuleNotFoundError: No module named 'pygls.features'

It looks like "pygls" is "0.10.2"

(venv) esbonio-check$ pip freeze | grep pygls
pygls==0.10.2

Looking at this issue, it looks like 0.10.x is not yet supported. #144

You may need to adjust the package dependencies.

Misc

As a workaround, I set the pygls version to 0.9.x as shown below, and it started.

pip install -U esbonio[lsp] pygls==0.9.1

Thank you for such a detailed issue report!

I'm about to merge #148 which should result in esbonio v0.5.1 being released with this issue resolved. Feel free to re-open this issue if the problem persists.

A similar issue still persists with latest version of esbonio, this time the module attrs can't be found:

$ pip freeze | grep esbonio
esbonio==0.16.1

Python:

$ python --version
Python 3.10.6

Error:

$ python -m esbonio
Traceback (most recent call last):
  File "/usr/lib/python3.10/runpy.py", line 196, in _run_module_as_main
    return _run_code(code, main_globals, None,
  File "/usr/lib/python3.10/runpy.py", line 86, in _run_code
    exec(code, run_globals)
  File "/home/user/.local/lib/python3.10/site-packages/esbonio/__main__.py", line 4, in <module>
    from esbonio import cli

    from pygls.protocol import default_converter
  File "/home/user/.local/lib/python3.10/site-packages/pygls/protocol.py", line 32, in <module>
    import attrs
ModuleNotFoundError: No module named 'attrs'

But attrs is installed:

$ pip freeze | grep attrs
attrs==21.2.0
cattrs==22.2.0

The version of pygls is:

$ pip freeze | grep pygls
pygls==1.0.1

[alcarney]

It looks like import attrs was only introduced in 21.3.0 (originally only import attr was available).
Upgrading your installation of attrs to at least that version should resolve the issue.

That fixes it, thanks!
