如何使用全局安装的gulp模块？

Question

I tried this tutorial to basically setup my gulp project and activate less processing and watching. It works. Now I'd like to install the modules globally, in order to acces them from everywhery on the machine and not to installa them for every project:

npm install --global gulp-less
npm install --global gulp-watch
npm install --global gulp-autoprefixer
npm install --global gulp-plumber

Now I want to run gulp in my project folder, but gulp cannot find the globally installed modules:

$ cd /my/project
$ gulp
module.js:327
    throw err;
    ^

Error: Cannot find module 'gulp-less'
    at Function.Module._resolveFilename (module.js:325:15)
    at Function.Module._load (module.js:276:25)
    at Module.require (module.js:353:17)
    at require (internal/module.js:12:17)
    at Object.<anonymous> (/root/temp/gulptest/gulpfile.js:9:12)
    at Module._compile (module.js:409:26)
    at Object.Module._extensions..js (module.js:416:10)
    at Module.load (module.js:343:32)
    at Function.Module._load (module.js:300:12)
    at Module.require (module.js:353:17)
    at require (internal/module.js:12:17)

How to get it working and use global gulp modules?

Answer 1

The solution was npm-link . I had to link all my local packages to global counterparts:

npm link gulp
npm link gulp-less
npm link gulp-watch
npm link gulp-autoprefixer
npm link gulp-plumber
npm link path

Now it works.

1. Install gulp globally:

If you have previously installed a version of gulp globally, please run npm rm --global gulp to make sure your old version doesn't collide with gulp-cli.

$ npm install --global gulp-cli

2. Install gulp in your project devDependencies:

$ npm install --save-dev gulp

For what it's worth, I solved this by placing this line at the top of my gulpfile.js

module.paths = module.paths.concat(module.parent.paths);

My parent module knew my npm global directory, but while running gulpfile.js, a child module seems to be created which doesn't. Instead, module paths is only relevant to the current directory from where the project is being run from and then each previous directory back to the root of my drive.
