Windows PowerShell将在Windows 10上安装NativeScript

Question

I try to install NativeScript on Windows 10 from Admin PowerShell console.

https://docs.nativescript.org/start/ns-setup-win

I type this command and obtain the following error:

@powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((new-object net.webclient).DownloadString('https://nativescript.org/setup/win-avd'))"

Answer 1

You're running the command from PowerShell when you need to run it from CMD command prompt.

Run this from CMD:

@powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((new-object net.webclient).DownloadString('https://nativescript.org/setup/win-avd'))"

Here, @powershell means "don't echo the command and run powershell.exe". It means something completely different in PowerShell itself, where @powershell means "search the path and execute a program with the literal name @powershell before the extension" or "use the variable $powershell as a splat variable" depending on your PowerShell version.

If you're running it in Powershell, you'll need to run just:

iex ((new-object net.webclient).DownloadString('https://nativescript.org/setup/win-avd'))

As always, be extremely careful about running these commands that download arbitrary code and execute it immediately.
