'tns' is not recognized as an internal or external command, operable program or batch file. NativeScript

Question

I am new to NativeScript and am currently going through the installation steps described here (http://docs.nativescript.org/angular/tutorial/ng-chapter-1) and I just completed executing the PowerShell script

@powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((new-object net.webclient).DownloadString('https://raw.githubusercontent.com/NativeScript/nativescript-cli/production/setup/native-script.ps1'))"

and then I run

tns doctor 

and I get

 C:\>tns doctor 'tns' is not recognized as an internal or external command, operable program or batch file.

Answer 1

Use this code

npm install --global nativescript

I had the same isssue and installing nativescript solved it.

Answer 2

If you are on Windows you need to add the the npm global directory to your path.

1. Control Panels -> System
2. Advanced System Settings (Link on Left side)
3. Environmental Variables (Button)
4. Scroll down for Path, and then click Edit (Button)
5. Append to the end: ;%USERPROFILE%\AppData\Roaming\npm

Make sure you get the semicolon.

This should work on Windows 7. I can get you the steps for other versions of windows; but hopefully this gets you going.
