Enable Feature: Office SharePoint Server Publishing in site collection and Site Feature. For example, both feature are enabled.

This Feature creates the Pages library.

If this Feature is not enabled, you will receive The following error message when setting The welcome page: The site is not valid. The 'page' document library is missing.

Use the SharePoint object model:

using (SPSite site = new SPSite("http://sharepoint.com"))    {    using (SPWeb web = site.RootWeb)        {        SPFolder rootFolder = web.RootFolder;        rootFolder.WelcomePage = "Pages/HomePage.aspx";        rootFolder.Update();      }   }

 

Use PowerShell:

$SiteUrl = "http://sharepoint.com"$Site = Get-SPWeb -identity $SiteUrl$RootFolder = $Site.RootFolder;$RootFolder.WelcomePage = "SitePages/HomePage.aspx";$RootFolder.Update();$Site.Dispose()
