自定义节点模块以安装依赖项

Question

Currently I have a custom Yeoman generator for some applications. This generator requires some dependencies and configurations.

1 - GruntJS to be installed globally;

2 - Bower to be installed globally;

3 - Yeoman to be installed globally;

4 - Some other configurations to be in place;

Question : Is there any tool to manage this dependencies work flow?

Optimally, I'm hoping for a two-step process

1 - Install Node.Js

2 - npm install my-generator

The second step will be responsible for installing all the packages globally.

I saw some examples that used preinstall script in the package.json like below:

...
scripts: {
  preinstall: 'npm install bower -g; npm install grunt-cli -g'
}
...

This solution did not work for me and I also read in several places that this is an anti-pattern.

Any help appreciated!

Answer 1

It's antipattern because npm normally downgrades the superuser permission before execute preinstall scripts. But in order to install global packages you have to execute it as sudo . The problem is that you need to make your instalation unsafe by giving superpowers to npm install scripts.

You can do it by creating a .npmrc file in your project root directory with the following content:

unsafe-perm = true

You package.json will look like:

{
  "name": "foo",
  "version": "1.4.4",
  "scripts" :  { 
    "preinstall" : "npm install -g bower; npm install -g grunt-cli"
  }
}

Then you can run

sudo npm install
