npm install lefthook error

[jimyhdolores]

🔧 Summary

When installing lefthook using npm on Windows, the installation fails due to a platform-specific dependency (@css-inline/css-inline-linux-x64-gnu). This does not happen when using pnpm, which correctly handles platform-specific optional dependencies.

Steps to reproduce

1. On a Windows machine (OS: win32, CPU: x64)
2. Initialize a Node project: npm init -y
3. Run: npm install lefthook

This will fail with the following error:

Unsupported platform for @css-inline/css-inline-linux-x64-gnu@0.15.0: 
wanted {"os":"linux","cpu":"x64"} (current: {"os":"win32","cpu":"x64"})

Expected results

The installation should skip incompatible optional dependencies and complete successfully on Windows, similar to the behavior with pnpm.

Actual results

Installation fails entirely when using npm due to an unsupported platform error.

Possible Solution

• Either mark the dependency @css-inline/css-inline-linux-x64-gnu as optional or provide platform-specific variants (e.g., @css-inline/css-inline-win32-x64-gnu) depending on the current system.
• Alternatively, adjust packaging so platform-specific binaries are only resolved during runtime, or provide fallback handling via JS if the native binary is missing.
