我在Windows上安装了npm 6.4.1和node v10.15.3，因此我尝试按照网站上的所有步骤安装Express Generator，并在尝试运行npm start时得到此提示

> node ./bin/www
Port 3000 requires elevated privileges
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! myapp@0.0.0 start: `node ./bin/www`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the myapp@0.0.0 start script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
