将 node_modules 安装到供应商 [英] Install node_modules to vendor

问题描述

如何在本地为每个项目安装 npm 模块到 vendor/node_modules 并使 package.json 文件看到它们.

How can I install npm modules locally for each project to vendor/node_modules and make package.json file see them.

我不想将 package.json 移动到供应商文件夹

我有 bower 并且在 .bowerrc 中指定了 bower_components 路径 - 这非常简单.

I have bower and in .bowerrc I specify the bower_components path - that is super easy.

我如何使用 npm 做到这一点?

How can I do that with npm ?

我已经阅读了文档、npmrc 文档、这里的一些问题、谷歌搜索、浪费了一个多小时 - 仍然没有运气.对于这么简单的任务来说，这太难了.

I`ve read the docs, npmrc docs, some questions here, googled, wasted more than an hour - still no luck. This is ridiculously hard for such an easy task.

我不在乎缺点，只要最后告诉我怎么做就行了.

I don't care about minuses, just tell me how to do that finally.

推荐答案

对于安装到任意子文件夹中的 node_modules 文件夹似乎没有内置方法这一事实感到沮丧，我来了使用以下两个脚本找到一个偷偷摸摸的解决方案:

Frustrated by the fact that there seems to be no built in way to install into a node_modules folder in an arbitrary subfolder, I came up with a sneaky solution using the two following scripts:

preinstall.js

var fs = require("fs");
try
{
    fs.mkdirSync("./app/node_modules/");
}
catch(e)
{
}

try
{
    if(process.platform.indexOf("win32") !== -1)
    {
        fs.symlinkSync("./app/node_modules/","./node_modules/","junction");
    }
    else
    {
        fs.symlinkSync("./app/node_modules/","./node_modules","dir");
    }
}
catch(e){}

postinstall.js

var fs = require("fs");
try
{
    if(process.platform.indexOf("win32") !== -1)
    {
        fs.unlinkSync("./node_modules/");
    }
    else
    {
        fs.unlinkSync("./node_modules");
    }
}
catch(e){}

您需要做的就是在 package.json 文件中使用它们，方法是将它们添加到 scripts 选项:

All you need to do is use them in your package.json file by adding them to the scripts option:

"scripts": {
    "preinstall": "node preinstall.js",
    "postinstall": "node postinstall.js"
},

那么，最大的问题是:它有什么作用?

So, the big question is: what does it do?

1. 好吧，当您调用 npm install 时，preinstall.js 脚本会触发，它会在您想要的子文件夹中创建一个 node_modules.然后它从 npm 期望的 node_modules 创建一个 symlink 或(Windows 中的 shortcut)到真正的 >node_modules.

1. Well, when you call npm install the preinstall.js script fires which creates a node_modules in the subfolder you want. Then it creates a symlink or (shortcut in Windows) from the node_modules that npm expects to the real node_modules.

然后 npm 安装所有依赖项.

Then npm installs all the dependencies.

最后，一旦安装了所有依赖项，postinstall.js 脚本就会触发，从而删除 symlink！

Finally, once all the dependencies are installed, the postinstall.js script fires which removes the symlink!
