In VS2015, opening a web project / solution using node packages (for example, gulpfile.js) will cause VS to automatically run "npm install" and install all the packages. VS2015 comes with the old version of npm (1.4.19), which does not perform a “flat” installation of package dependencies, which forces you to create paths that contain more than 260 characters. It really hurts when it happens every time Visual Studio opens. I found some workarounds (including http://jameschambers.com/2015/09/upgrading-npm-in-visual-studio-2015/ ), but ideally there would be a setting somewhere to turn off "auto npm install "or something like that I just either can’t find the setting, or it doesn’t exist.
