Nvm

From WPKG | Open Source Software Deployment and Distribution
Jump to: navigation, search

This Package installs the node version manager developed by Corey Butler on Github (https://github.com/coreybutler/nvm-windows), for this Package i used the noinstall Version and created the Settings.txt with these contents:

root: C:\opt\nvm path: C:\opt\nodejs arch: 64 proxy: none

You will have to set the root and the copy paths in the package to where you want to install the nvm. The path variable points to where nvm creates the Link it uses to switch between different node versions.

After installation of the Package it is necessary to reboot the Computer or use this Powershell script which forces Windows to reread all System environment Variables because the SETX does not work exactly as intended with WPKG:

Powershell[edit]

if (-not ("win32.nativemethods" -as [type])) {
    # import sendmessagetimeout from win32
    add-type -Namespace Win32 -Name NativeMethods -MemberDefinition @"
	[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
	public static extern IntPtr SendMessageTimeout(IntPtr hWnd, uint Msg, UIntPtr wParam, string lParam, uint fuFlags, uint uTimeout, out UIntPtr lpdwResult);
"@
}

	$HWND_BROADCAST = [intptr]0xffff;
	$WM_SETTINGCHANGE = 0x1a;
	$result = [uintptr]::zero

	# notify all windows of environment block change
	[win32.nativemethods]::SendMessageTimeout($HWND_BROADCAST, $WM_SETTINGCHANGE,
	[uintptr]::Zero, "Environment", 2, 5000, [ref]$result);

Whenever i tried to execute this Script with wpkg it would go into a endless loop and i had to force quit powershell to continue, maybe someone knows a way to achieve this so this can be used without needing a reboot
