我是新手并且正在学习如何在WordPress上学习Udemy课程。我在Terminal非常缺乏经验，课程的一部分已经转移到学习JavaScript，他正在使用gulp watch来查看更改自动更新。
尽我所能，我无法让Gulp安装在运行El Capitan的MBP上，我一直看到有关它被弃用的消息，并按照this link on Medium上的信息
问题是，作为初学者，我不知道这是什么意思。我已将目录更改为我应该在的文件夹结构的根目录，并且已按照指示复制了四个文件（gulpfile.js，package.json，settings.js和webpack.config.js）但不管我尝试的是什么我收到以下错误：
Dans-MBP:app danmichael$ npm install gulp
npm WARN deprecated gulp-util@3.0.8: gulp-util is deprecated - replace it, following the guidelines at https://medium.com/gulpjs/gulp-util-ca3b1f9f9ac5

我在安装命令之前尝试使用'sudo'也无济于事。最近（今天）我现在也看到了'EACCES'错误，我不知道如何修复，据我所知，我设置为Adminstrator（仅限该Mac的用户）：
npm ERR! path /Users/danmichael/Local Sites/fictional-university/app/node_modules/gulp

如果我运行node -v，我会得到v8.11.1
如果我运行gulp -v，我将获得CLI版本3.9.1，本地版本3.9.1
但我仍然无法运行gulp watch。
