Hi.

I installed gulp globally. A warning indicating that the dependent library is vulnerable has been output.

I execute npm audit command. Result is below.

$ npm audit

                       === npm audit security report ===

found 5 vulnerabilities (1 low, 4 high) in 1418 scanned packages
  5 vulnerabilities require semver-major dependency updates.

I should execute npm audit fix command? Or I need to execute npm update minimatch/lodash?

npm audit is broken and reports things that are not really security issues for us (dev dependencies 3 levels deep that don't even get installed). None of these warnings pose any real risk to you as a user of gulp, so you can ignore them. If you feel strongly enough about it you can open a ticket on npm and ask them to fix audit, but I don't think it will happen any time soon.

Those issues have been "known" forever because they are references to gulp 3 (notice the gaze dependency?).
Like contra said, they don't effect us.

Sorry. I was installing gulp at npm without specifying the version.

Without specifying the version, running 'npm install gulp' seemed to install version 3.9.1.

The problem was solved by specifying the version of gulp and running npm install.
