Problem description
I am experiencing the same issue as with #505 but with a different flavor likely cos of NixOs. Mason seems to expect a python binary in PATH even when a provider is given.
On NixOS one can install Neovim via program options and enable a python provider to be installed with it. Something like:
# Install and configure neovim
programs.neovim = {
enable = true;
withPython = true;
};
Nix then installs Neovim and a python executable together and set that executable as the python provider:
provider.python: require("provider.python.health").check()
Python 3 provider (optional) ~
- Using: g:python3_host_prog = "/nix/store/<nix-sha1>-neovim-0.10.0/bin/nvim-python3"
- Executable: /nix/store/<nix-sha1>-neovim-0.10.0/bin/nvim-python3
- Python version: 3.11.9
- pynvim version: 0.5.0
- OK Latest pynvim is installed.
Python virtualenv ~
- OK no $VIRTUAL_ENV
However still, installation of packages which use the python or python3 binary fail with Unable to find python3 installation in PATH. Tried the following candidates: python3, python.
Perhaps I am misunderstanding and Mason only uses the PATH binaries, but the discussion in #505 points to the opposite.
Thanks.
Expected behavior
The python binary specified by the python provider is used to install mason packages.
Steps to reproduce
- Install neovim on NixOS
- Ensure that no system wide python installation exists
- Attempt to install a mason package with requires the python binary (e.g.,
ruff) - Watch it fail with
Unable to find python3 installation in PATH. Tried the following candidates: python3, python.
