Why can't I run the bower update command in Package Manager Console

Its an existing project and I want to upgrade jquery version in it. For that on package console manager(PMC) I ran bower update jquery --force-latest and even bower update jquery but to no avail. It's giving error as shown in screenshot.

My bower.json file is in the project which I have located in PMC's Default Project as shown in figure:

I later changed the version of jquery in .json file from "jquery": "2.1.3" to "jquery": "3.3.1" . Still no luck! I'm new to this and don't now what am I missing?

Here's my bower.json file;

I was using Visual Studio (VS 2013) which contains old GIT version. I updated it with latest and command worked successfully. Don't forget to remove the older version of GIT through Control Panel

Between, I figured out that command could be also be run through ordinary command prompt.
