shiny package with Golem - error in the dependecies while install


I'm kind of new to the shiny application as a package (using golem) so my struggle is maybe a silly one..

I've just done a test to using the provided template with golem to see if I could generate and install the package. It seems that I cannot do it..I've do all relevant steps in dev1, 2 and 3 and the package is generated with no error. However when I try to install it it always says that I'm missing the dependencies that are listed in the DESCRIPTION file (under the import section).

Shouldn't it be all installed as I install my package from source?
Any guidance here is much appreciated..

Thank you
