Cannot start pylsp-mypy

[ubaldot]

I am using Vim with lsp and I am using pylsp with the following setting:

var pylsp_config = {
  'pylsp': {
    'ConfigurationSources': 'flake8',
    'plugins': {
      'pycodestyle': {
        'enabled': false},
      'pyflakes': {
        'enabled': true},
      'pydocstyle': {
        'enabled': false},
      'mccabe': {
        'enabled': false},
      'autopep8': {
        'enabled': false}, }, }, }

I am invoking the lsp with pylsp ----check-parent-process -v and in my pyproject.toml I have the following:

         [tool.pylsp-mypy]
         enabled = true
         live_mode = true
         strict = true
         exclude = ["tests/*", "manual_tests/*", "docs/*"]

All pylsp features work perfectly but pylsp-mypy. Running mypy from iTerms works well. mypyversion is 1.11.2 and pylsp v1.7.3. I don't have any mypy-related configuration settings in ~/.config and similar.

What does the server log say?

EDIT: I am not sure if it is exactly what you asked, but here is the initialization request log:..

For some obscure reasons now it works.

I reopen because whilst it works on Linux, pylsp-mypy does not seem to work on macos. Here is few messages from the server:

If you start pylsp with -vv you should get debug output. Is any of that from pylsp-mypy?

[ubaldot]

I think I found it:

2024-09-25 22:01:42,476 CEST - INFO - pylsp.config.config - Failed to load pylsp entry point 'pylsp_mypy': (typing-extensions 4.5.0 (/opt/homebrew/Caskroom/miniconda/base/envs/dymoval_dev/lib/python3.11/site-packages), Requirement.parse('typing-extensions>=4.6.0'), {'mypy'})

it seems that the plugin requires typing-extensions>=4.6.0 but I have the 4.5.0 installed. EDIT: solved by updating the package.

[Richardk2n]

It is mypy that requires typing-extensions>=4.6.0. I guess there is a check that fires once it is imported by pylsp-mypy. How you manged to install mypy without its dependencies fulfilled, I do not know.

[ubaldot]

I simply conda install mypy :)
