"npm run build" fails when source open with Visual Studio Code

[clinicaloffice]

For some reason, whenever I try to build my library with the "npm run build" command and I have my library source open in Visual Studio Code (1.21.1), the npm build command errors out. If I close VS Code and try again it works just fine.

I know this is likely a file locking issue in VS Code and nothing to do with generator-angular2-library but I've been searching for a few weeks for a solution and nobody seems to have an answer. I've tried other editors such as Atom and don't have the same problem so it is definitely local to VS Code.

If anyone has run into this and has a fix I'd appreciate it. Please don't say use another editor as I've tried a bunch of them and I find VS Code does everything I want (except this problem) just the way I like.

Thanks,

John
