Error: Cannot find module 'require-dir'

错误：找不到模块'require-dir'

You've installed gulp but have not installed its tasks' dependencies. E.g. if a gulp task has any require('') calls, then it depends on require-dir. Those dependencies are probably in your project's package.json file. To install all the dependencies run:

您已安装gulp但尚未安装其任务的依赖项。例如。如果gulp任务有任何require（''）调用，那么它取决于require-dir。这些依赖项可能在您的项目的package.json文件中。要安装所有依赖项，请运行：

npm install
