通过Visual Studio中的Package Console Manager将jQuery版本从2.1.1降级到1.9.1

Question

I have jQuery version 2.1.1 and wanted to downgrade to 1.9.1, i have tried Install and Update commands, but both are failing claiming that a more recent version of jquery is installed for my project:

PM> Update-Package jQuery -Version 1.9.1
PM> Install-Package jQuery -Version 1.9.1 

I thought that package manager would be taking care of this process but it seems not. I cannot uninstall it because of dependencies of others installed packages.

What are my options?

Answer 1

Delete the jQuery entry in your packages.config file, then just run the install for the specific version.

eg

PM> Install-Package jQuery -Version 1.9.1 

You can then simply delete the old JQuery version (only one script file).

PS: I recommend you go with jQuery 1.11.0 if you can :)

Answer 2

I also encountered a similar case where I wanted to downgrade version of jquery which was in turn acting as dependency for various other components.

The easiest way I found was that go to Nuget Package Manager > Manage Nuget Packages for Solution

Select relevant package (jquery for me) under Installed tab on left hand side of screen. On right hand side, You will be seeing a dropdown next to Version label. Select the version to which you want to downgrade (or upgrade) & Click on Install.

PS: This is available for VS2015+
