`Fatal error: Unable to find local grunt.`: why asking for local grunt, if I have a global?
gruntjs, javascript, node.js
Solution
It's due to npm's foldering:
- Install it locally if you're going to `require()` it.
- Install it globally if you're going to run it on the command line.
The Gruntfile itself depends on `require('grunt')` being available, requiring a local install.
$ npm install grunt
And, having `grunt(1)` as an available command makes using the tool easier, requiring a global install.
$ npm install -g grunt-cli
To have both, though, it has to be installed in both folders.
Problem
I'm a noob in Node.js and trying to use `grunt-contrib-concat` to build my javascript library from multiple source files. I've created a virtual environment, activated it, globally installed `grunt` and `grunt-cli`, written `Gruntfile.js` and `package.json` files for my project. To summarize: ``` $ nodenv NODEENV $ source NODENV/bin/activate (NODEENV)$ npm install -g grunt-cli ... (NODEENV)$ npm install -g grunt ... (NODEENV)$ cd myproject (NODEENV)$ ls myproject Gruntfile.js package.json src test README.md (NODEENV)$ grunt test grunt-cli: The grunt command line interface. (v0.1.13) Fatal error: Unable to find local grunt. If you're seeing this message, either a Gruntfile wasn't found or grunt hasn't been installed locally to your project. For more information about installing and configuring grunt, please see the Getting Started guide: http://gruntjs.com/getting-started ``` What I don't understand is why `grunt-cli` is telling me that it wants a local per-project version of `grunt` if I've already got a globally installed one? Could you also suggest a way to fix the error?
