The pyright language server must be available on the path. You can install it in many ways, choose the one you like the most in the official guide (You must follow the "command line" section).

The most important part is that you need to have pyright-langserver on your path.

You can install the extension directly via the Lapce editor, in the extensions tab. Just search for Python (pyright).

Obs: Don't forget to check the author name.

All additional functionality and configuration should work the same as described in the README for pyright.

The recommended way of configuring it would be be using a pyproject.toml file. You can see an example section bellow:

[tool.pyright]
venvPath = "./"
venv = ".venv"
reportMissingImports = true
reportMissingTypeStubs = false
typeCheckingMode = "off"
pythonVersion = "3.11.1"

Before building, you must ensure that you have the wasm32-wasi target setup.

rustup target add wasm32-wasi

cargo build --target wasm32-wasi

cargo build --release --target wasm32-wasi

cd <lapse_dir>/dev.lapce.Lapce/plugins

mkdir lapce-pyright

cd lapce-pyright

ln -s <source_dir>/target/wasm32-wasi/debug/lapce-pyright.wasm ./bin/
