javascript - 为什么我收到 "Refusing to install purify-css as a dependency of itself"错误？

Question

我正在尝试使用 this库以仅获取使用的 css 规则。文档说我应该使用这个命令，但是当我使用它时，我收到以下错误:

npm install --save purify-css

npm ERR! Darwin 16.1.0
npm ERR! argv "/usr/local/Cellar/node/6.9.1/bin/node" "/usr/local/bin/npm" "install" "--save" "purify-css"
npm ERR! node v6.9.1
npm ERR! npm  v3.10.8
npm ERR! code ENOSELF

npm ERR! Refusing to install purify-css as a dependency of itself

npm ERR! Please include the following file with any support request:
npm ERR!     /Users/fatih/Downloads/purifycss-master/npm-debug.log

当我转到该元素的根目录并使用此命令时，我收到此错误:

bin/purifycss

Error: Cannot find module 'yargs'

如有任何帮助，我将不胜感激!

Refusing to install purify-css as a dependency of itself

Answer 1

您使用的是 gulp、grunt 还是 webpack？我正在使用 gulp，而且当我尝试安装时也出现了问题。

purify-css - 例如，对于 gulp 来说是不正确的。对于 gulp 需要使用:gulp-purifycss(https://www.npmjs.com/package/gulp-purifycss 有点不对，因为 var purify = require('gulp-purify'); 不正确，请在此处更正 https://github.com/purifycss/gulp-purifycss)。

希望对您有所帮助。
