“Npm install --global"和“--保存"一起? [英] "Npm install --global" and "--save" together?

问题描述

我想知道在 npm install 命令中使用 --global 和 --save 参数是否有意义.例如:

npm install gulp -g -s

据我所知，npm 系统文件夹中没有 package.json，所以我想答案是否定的，但我想清除所有疑问.

解决方案

npm install 命令不支持全局安装模块并一步将其保存到 package.json.

然而，有一种方法可以间接地全局安装模块.package.json 支持这样的预安装属性:

脚本":{预安装":npm install -g gulp"}

只要你执行 npm install，gulp 就会被全局安装.请注意，您的当前用户需要获得写入全局节点模块目录的权限.

I was wondering if makes any sense to use in the npm install command the --global and the --save parameters all together. For example:

npm install gulp -g -s

As far as I know there is no package.json in the npm system folder, so I suppose the answer is "no", but I want to clear all doubt.

解决方案

The npm install command does not support installing a module both globally and save it to the package.json in one step.

There is, however, a way to install a module globally indirectly. The package.json supports a preinstall property like so:

"scripts": {
  "preinstall": "npm install -g gulp"
}

As soon as you execute npm install, gulp will be installed globally. Please note that your current user then needs permission to write to your global node module directory.
