I'm installing a module from the NPM registry with this mand:

npm install dc

All files are installed successfully, but dc fails to resolve a dependency.

$ node web-test.js

module.js:340
    throw err;
    ^
Error: Cannot find module 'sinon'

• javascript
• node.js
• module

To require the module sinon, you must npm install sinon, not some other module.

Edit: Since you changed your question to installing dependencies, sinon is a devDependency for the package dc, so in order to install it, you must navigate to the module's folder and run npm install. An install off of the global registry will not install developer dependencies for you, but a local run of install will install both normal and development dependencies.

dc.js has dependency on

jsdom, sinon, jquery, vows.

For that install all those dependency

npm install jsdom
npm install sinin
npm install jquery
npm install vows
