Unable to Connect with Power BI Service using PowerShell

I have installed PowerShell for Power BI using following Code. 

Install-Module -Name MicrosoftPowerBIMgmt

It is installed successfully.

Now, I used following code-snippet to connect with Power BI Service.

Login-PowerBI

When I executed the code it shows me an error like:

Login-PowerBI : The 'Login-PowerBI' command was found in the module 'MicrosoftPowerBIMgmt.Profile', but the module 
could not be loaded. For more information, run 'Import-Module MicrosoftPowerBIMgmt.Profile'.
At line:1 char:1
+ Login-PowerBI
+ ~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (Login-PowerBItring) [], CommandNotFoundException
    + FullyQualifiedErrorId : CouldNotAutoloadMatchingModule

Please refer the screenshot.

I have also tried to import  module MicrosoftPowerBIMgmt.Profile using following code:

Import-Module MicrosoftPowerBIMgmt.Profile

It shows me following error:

Import-Module : Could not load file or assembly 'netstandard, Version=2.0.0.0, Culture=neutral, 
PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. Reference assemblies should not be loaded for 
execution.  They can only be loaded in the Reflection-only loader context. (Exception from HRESULT: 0x80131058)

Below is a screenshot for the same.

Please suggest an appropriate solution for it
