“源文档中没有元素匹配......”（NuGet安装错误）

Question

I'm trying to install a package via the package manager console for PowerBI, and I keep getting this error:

    Install-Package : An error occurred while applying transformation to 'Views\web.config' in project 'Application': No element in the source document matches 
'/configuration/system.web/compilation/assemblies'
At line:1 char:1
+ Install-Package Microsoft.PowerBi.AspNet.Mvc
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Install-Package], InvalidDataException
    + FullyQualifiedErrorId : NuGetCmdletUnhandledException,NuGet.PowerShell.Commands.InstallPackageCommand

The command I'm trying to run is:

Install-Package Microsoft.PowerBi.AspNet.Mvc

I've tried installing different versions, that hasn't worked either.

Not really sure why this is failing, I've never had issues with the package manager console before.

Answer 1

Okay so not five minutes after I posted this, I figured out the issue. In my web.config, this block of code was not present

<compilation>
      <assemblies>
      </assemblies>
      <buildProviders>
      </buildProviders>
  </compilation>

Simply adding that between the <system.web> </system.web> headers allowed the install to work, and now my web.config has the following code:

<compilation>
      <assemblies>
          <add assembly="Microsoft.PowerBI.AspNet.Mvc, Version=1.1.1.16190, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
      </assemblies>
      <buildProviders>
      </buildProviders>
  </compilation>

Not really sure why the package manager can't create its own elements.. but all is well now. I'll leave this up just in case someone else has the same issue.
