*Assume I install project packages with `npm install` that looks into `package.json` for modules to be installed.* **假设我使用`npm install`安装项目包，查看`package.json`以获取要安装的模块。** *After a while I see that I don't need some specific module and remove its dependency from `package.json` .* **过了一会儿，我发现我不需要一些特定的模块，并从`package.json`删除它的依赖。** *Then I remove some other modules from `package.json` because they are not needed anymore and others are replaced with alternatives.* **然后我从`package.json`删除了一些其他模块，因为它们不再需要了，而其他模块则替换为替代模块。**

*Now I want to clean `node_modules` folder so that only modules listed in `package.json` stay there and the rest must go, something like `npm clean` .* **现在我想清理`node_modules`文件夹，以便只有`package.json`列出的模块保留在那里，其余的必须去，比如`npm clean` 。** *I know I can remove them manually but would like to have some nice ready to use sugar functionality for that.* **我知道我可以手动删除它们但是希望有一些很好的准备使用糖功能。**

*You could remove your node\_modules/ folder and then reinstall the dependencies from package.json.* **您可以删除node\_modules /文件夹，然后从package.json重新安装依赖项。**

rm -rf node_modules/
    npm install

*This would erase all installed packages in the current folder and only install the dependencies from package.json.* **这将擦除当前文件夹中的所有已安装的包，并仅从package.json安装依赖项。** *If the dependencies have been previously installed npm will try to use the cached version, avoiding downloading the dependency a second time.* **如果先前已安装依赖项，则npm将尝试使用缓存版本，从而避免第二次下载依赖项。**
