How to clean node_modules folder of packages that are not in package.json?
提问by Sergei Basharov
Assume I install project packages with npm installthat looks into package.jsonfor modules to be installed. After a while I see that I don't need some specific module and remove its dependency from package.json. Then I remove some other modules from package.jsonbecause they are not needed anymore and others are replaced with alternatives.
假设我安装了项目包，npm install它会查找package.json要安装的模块。过了一会儿，我发现我不需要某些特定的模块并从package.json. 然后我删除了一些其他模块，package.json因为不再需要它们，而其他模块则替换为替代品。
Now I want to clean node_modulesfolder so that only modules listed in package.jsonstay there and the rest must go, something like npm clean. I know I can remove them manually but would like to have some nice ready to use sugar functionality for that.
现在我想清理node_modules文件夹，以便只有列在package.json那里的模块留在那里，其余的必须去，比如npm clean. 我知道我可以手动删除它们，但想要一些很好的准备使用糖功能。

I think you're looking for npm prune
我想你正在寻找 npm prune
npm prune [<name> [<name ...]]This command removes "extraneous" packages. If a package name is provided, then only packages matching one of the supplied names are removed.
Extraneous packages are packages that are not listed on the parent package's dependencies list.
npm prune [<name> [<name ...]]此命令删除“无关的”包。如果提供了包名称，则仅删除与提供的名称之一匹配的包。
无关包是未在父包的依赖项列表中列出的包。
See the docs: https://docs.npmjs.com/cli/prune

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. If the dependencies have been previously installed npm will try to use the cached version, avoiding downloading the dependency a second time.
这将删除当前文件夹中所有已安装的包，只安装 package.json 中的依赖项。如果之前已经安装了依赖项，npm 将尝试使用缓存的版本，避免再次下载依赖项。

Due to its folder nesting Windows can't delete the folder as its name is too long. To solve this, install RimRaf:

rimraf node_modules
