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
This appears to be a bug that we introduced in Update 6 that causes npm install errors if the path to your npm install directory (usually in your AppData folder) has a space in the path. The simple workaround is to change your npm install directory:
npm config set prefix "C:\Folder\With\No\Spaces"
And then build again in VS. We will get this fixed up and released in Update 7 as soon as we can.
Sorry for the inconvenience.
