Node.js Question

Peer dependency issue in npm Node modules

I have run into some issues in installing the grunt related node module dependencies for my project,

I want to install the selected dependencies using one command, so I used below,

npm install grunt grunt-contrib-jshint grunt-cli grunt-contrib-watch grunt-exec grunt-contrib-symlink grunt-contrib-clean grunt-contrib-copy grunt-text-replace grunt-git --save-dev


Got error like 'grunt-exec@0.4.6 requires a peer of grunt@~0.4 but none was installed.'
So as per the feedback from googling, found we can hardcode the dependency version like below fix,

npm install grunt@~0.4 grunt-contrib-jshint grunt-cli grunt-contrib-watch grunt-exec grunt-contrib-symlink grunt-contrib-clean grunt-contrib-copy grunt-text-replace grunt-git --save-dev


It has temporarily fixed the issue for sometime but now I get an error like
'grunt-git@1.0.0 requires a peer of grunt@~1.0.1 but none was installed.'

So it seems that the grunt plugins needs different version of same dependency - grunt(in my case). Installing the plugins one by one instead of a cluster also wont resolve the issue

Update

Since people want to take points away from this answer w/o reading the comments to see that a solution was found, here's what we arrived at:

An instance like this, you should review the previously released versions for grunt-git, find an older version that meets your reqs (v0.3.8) and double check if the features you want to use with the plugin are available or not. If it is, try npm install grunt-git@0.3.8 --save-dev. Releases can be found here:

Original Solution

First you'll want to initialize your project by creating a package.json file by running the command npm init. You'll be prompted to answer several questions, you can change the default values if you like.

Once the project has been initialized, install the dependencies one at a time & include the flag --save or --save-dev. This will add the dependency to the package.json manifest. Example: npm install grunt-contrib-jshint --save-dev

Once you have all of your dependencies listed in your package.json file, you can then achieve a one-command install using npm install.

The NPM registry has a very detailed article on using package.json if you'd like to learn more.
