我已按照https://www.npmjs.com/package/webpack-cli/tutorial的说明操作，但收到此错误：
$ npm install webpack-cli
npm ERR! code ETARGET
npm ERR! notarget No matching version found for yeoman-generator@ev1stensberg-generator-Feature-getArgument.tar.gz-art-external
npm ERR! notarget In most cases you or one of your dependencies are requesting
npm ERR! notarget a package version that doesn't exist.
npm ERR! notarget
npm ERR! notarget It was specified as a dependency of 'webpack-cli'
npm ERR! notarget
我搜索了yeoman-generator并安装了它，但仍然遇到了同样的错误。我怎么能绕过这个？
