Problem with importing widgets-content

I was trying to import the widgets-content using Widget Importer & Exporter, but I received the following errors shown below. Has anyone encountered this while importing?
My WP version is 4.7.2.

Hi,

Make sure you install the plugin “Shapely Companion” before trying to import the data,
