Hi Team,
When I try to install n8n version 1.68.0 using the command pnpm install it’s failing on one prepared script.

These seem like issues with a Windows dev environment?
Here is the solution:

## Summary
The repository preparation script fails on Windows (cmd and PowerS… hell) due to cmd incompatible path when using `execSync` in the `prepare.mjs` script.
When running `pnpm install`, the preparation script fails with the following error:
```

```
It happens because `lefthook` is executed directly from the `node_modules` path in this line in `scripts/prepare.mjs`:
```javascript
execSync('./node_modules/.bin/lefthook install', { stdio: 'inherit' });
```
This works fine when using PowerShell directly, but cmd does not resolve `.` as current directory, and cmd is the [default shell on Windows when using `execSync`](https://nodejs.org/api/child_process.html#default-windows-shell).
This change replaces direct execution of `lefthook` with `npx`, which handles cross-platform path resolution automatically:
```javascript
execSync('npx lefthook install', { stdio: 'inherit' });
```

- [ ] PR Labeled with `release/backport` (if the PR is an urgent fix that needs to be backported)
It hasn’t been merged into master yet. So you need to open /scripts/prepare.mjs and change line 10 from
execSync('./node_modules/.bin/lefthook install', { stdio: 'inherit' });
to
execSync(`npx lefthook install`, { stdio: 'inherit' });
or use path.normalize() as
#!/usr/bin/env node
import { execSync } from 'node:child_process';
import { normalize } from "path";
// Skip lefthook install in CI or Docker build
if (process.env.CI || process.env.DOCKER_BUILD) {
process.exit(0);
}
const normalizedPathToCommand = normalize('./node_modules/.bin/lefthook');
execSync(`${normalizedPathToCommand} install`, { stdio: 'inherit' });
Hi @dobromyslov ,
