How to load the Visual C++ component "VCBuild.exe"? - node.js

Question

I tried to run "VCBuild.exe"
My environment:
Windows 10 Pro X64
node v7.9.0-x64
Visual Studio 2017
So,I've just run like this command.
$npm install --global --production windows-build-tools
But it doesn't work.
Errors are bellow:

Answer 1

The output says exactly what you need to do:
Please restart this script from an administrative PowerShell!
The build tools cannot be installed without administrative rights.
To fix, right-click on PowerShell and run "as Administrator".
If you run PowerShell (or the Command Prompt you used to run npm) as Administrator, then it should work.
