Recently I updated to Cordova Tools version 6 for Visual Studio I am now getting this error. Anytime I try to build my solution.
: BLD00401 : Could not find
I'd the same issue here. In my computer I'd to copy app.js from another folder:
C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\ApacheCordovaTools\Packages\vs-tac
I know this is not a good solution, but worked for me.
But in another computer here, I reinstalled with this command and worked (I closed VS prior to run this command, and started a new project):
npm install -g "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\ApacheCordovaTools\packages\vs-tac"
Hope these notes can help you out.
