Error after updating Kendo UI Builder 2.0.1 -> 2.1.0.23

Hey together,

yesterday we updated our Kendo UI Builder to the new version. Today I tried to migrate our actually App. That works. But when I'm clicking on Generate I'll get the following error in the output window at the bottom.

[16:16:26] INFO

I'm all done. Running npm install for you to install the required dependencies. If this fails, try running the command yourself.
