Typescript Error Developing Your First PowerBI Visual

Im new to Power BI and I have started doing the tutorials on Github called "Developing Your First Power BI Visual".

 

I am just stuck on one issue at the moment, I have managed to fix some of the typescript errors  related to d3-typings by following the installation instructions on Github. 

 

However, I am still getting errors (see below) and I am not sure what to do next. Is this related to other external library that I am missing.

    magtuto,

     

    I can run the project Sample Bar Chart. According to the error message, you need to specify related .ts file in tsconfig.json by using the "files" property.

      How do you specify related .ts file in tsconfig.json by using the "files" property?

       

      This is the only error I have but I don't have that /visualPlugin.ts anywhere

      TYPESCRIPT  /visualPlugin.ts : (8,147) Property 'Visual' does not exist on type 'typeof demo49B92E39CFB047F59CF0F0DEF084AE31'.

        visualPlugin.ts is auto-generated file. You can take a look at this file in ".tmp/precompile".

         

        Could you please clarify a name of class that implements IVisual interface?

        Please note that the same class name must be specified in visualClassName property of pbiviz.json.
