Using PnP PowerShell On Premises and Online

I have a hybrid environment with a publishing site on premises and collaboration sites in SharePoint Online.  I have some scripts that need to run against both environments (independently, not simultaneously -- there will be one run of the script for each environment).

I found Erwin's article about setting up my PnP-based scripts so that they can work with either environment here:

https://rencore.com/blog/using-the-officedev-pnp-powershell-cmdlets-for-both-on-prem-and-in-the-cloud/ 

but it seems to be a bit out of date.  I have followed the directions about the environment variables and tried to compensate for the changes to the pathing/naming of libraries on my own, but even so I am getting errors that are keeping my scripts from running.  The first is a Warning about "unapproved verbs", and the second is that "some required components are missing" even though I just downloaded and installed both the 2016 and Online releases for March 2017. I am trying to import the pnp commands at the top of my script with this:

Import-Module $pnpmodulepath -Force

where $pnpmodulepath is a string passed in as a parameter. I am currently passing in this string:

"C:\Users\[myusername]\AppData\Local\Apps\SharePointPnPPowerShellOnline\Modules\SharePointPnPPowerShellOnline\SharePointPnP.PowerShell.Online.Commands.dll"

Is there any updated guidance available for writing scripts that will run on multiple environments from the same machine?

Thanks in advance.
