react-native init Awesomeproject "npm ERR! Please try running this command again as root/Administrator." windows 10

Question

I am trying to follow the instructions for "Getting started with react-native".

I know that using windows for my development platform is experimental but this is what I am doing. I start a "Node.js command prompt" then do ...

> npm install -g react-native-cli
> react-native init AwesomeProject

... but I get this error ...

The error output suggest: Please try running this command again as root/Administrator., but how do I do that on a Windows 10 system?

UPDATE: Thank Louy your answer works. Here's a screen shot of what I ended up doing ...

Right click the Node.js command promtpt and select Run as Administrator.

UPDATE II: On subsequent iterations I got the same error. I what I had to do then was what Louy said to do in the comment:

delete the folder "C:\\Users\\plankton\\AppData\\Roaming\\npm-cache

UPDATE III:

I had run my Node.js command prompt as Administrator and I had deleted the folder "C:\\Users\\plankton\\AppData\\Roaming\\npm-cache and yet I still got the running this command again as root/Administrator error. I had to use Windows Explorer to unset the Read only and hidden properties off the "C:\Users\plankton\AppData` folder.

Answer 1

You need to start up your command line interpreter as an administrator.

• Open start menu
• Type "cmd"
• Right click and choose "Run as Administrator"

Then do the same as you did earlier.
