Lean installation instructions can be found
|
||
|
|
[here](https://leanprover-community.github.io/get_started.html#regular-install).
|
||
|
|
|
||
|
|
Once Lean is installed, you can install the Lean 3 language server by running
|
||
|
|
```sh
|
||
|
|
npm install -g lean-language-server
|
||
|
|
```
|
||
|
|
|
||
|
|
Note: that if you're using [lean.nvim](https://github.com/Julian/lean.nvim),
|
||
|
|
that plugin fully handles the setup of the Lean language server,
|
||
|
|
and you shouldn't set up `lean3ls` both with it and `lspconfig`.
