Alguns erros ao instalar o pacote EntityFramework.Commands -Version 7.0.0-rc1-final -pre

Boa tarde, fui tentar instalar o pacote EntityFramework.Commands, porém apareceu algumas coisas que não tinha visto ultimamente...

No meu notebook de casa, quando instalo vai tudo tranquilo, mas ao instalar no computador do trabalho, aparece as seguintes frases:

Where-Object : Cannot bind parameter 'FilterScript'. Cannot convert the "Name" value of type "System.String" to type "System.Management.Automation.ScriptBlock".
At C:\Users\gats\Desktop\projects-repository\QRAFlare\packages\EntityFramework.Commands.7.0.0-rc1-final\tools\init.ps1:3 char:19
+ if (Get-Module | ? <<<<  Name -eq EntityFramework) {
    + CategoryInfo          : InvalidArgument: (:) [Where-Object], ParameterBindingException
    + FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Microsoft.PowerShell.Commands.WhereObjectCommand

Join-Path : Cannot bind argument to parameter 'Path' because it is null.
At C:\Users\gats\Desktop\projects-repository\QRAFlare\packages\EntityFramework.Commands.7.0.0-rc1-final\tools\init.ps1:7 char:25
+ Import-Module (Join-Path <<<<  $PSScriptRoot EntityFramework.psd1) -DisableNameChecking
    + CategoryInfo          : InvalidData: (:) [Join-Path], ParameterBindingValidationException
    + FullyQualifiedErrorId : ParameterArgumentValidationErrorNullNotAllowed,Microsoft.PowerShell.Commands.JoinPathCommand

Tentei semana passada solucionar esse problema, porém nada.

Abraços.
