With a downloaded and installed version of Visual Studio Code 1.2.1, and a 64bit version of node.exe msi placed in my working directory (I am assuming that is correct), how
Had the same issue and in my case it was a problem with a vs code extension. Try running code as:
$ code --disable-extensions
Once in the editor, I ran my program in the debug mode and worked, and then started code with
$ code
And it continued working fine.
Hope it works for you.
