Please provide the entire, verbose log (add --verbose to the npm command). Put it inside triple ticks so the formatting works:

```
like this, output goes here
```

Also: what's your Windows version and Visual Studio version?

I also suspect that the error is accurate

error MSB4014: System.ArgumentException: The name "plugin:CLToolExe=clang-cl. exe" contains an invalid character ".".

Please can you post the file C:\Users\danny\AppData\Roaming\npm\node_modules\llnode\build\binding.sln
