I followed the strongloop pre installation requirments (http://docs.strongloop.com/display/SL/Installing+Node+and+StrongLoop+on+Windows) and everything was set without problems. However , each time I execute
npm install -g npm
the installation fails. In the npm-debug.log I see the reason for the failure is
info sqlite3@3.0.5 Failed to exec install script
sqlite3 was installed successfully in the global modules.
