After reading npm-json ( npm help json ), I have construct the package.json file as follows: {"name": "app name", "version": "0.1"} . The directory has the following structure:

/ |-- main.js |-- package.json

I am familiar with Node.js - do I need to reinstall all the modules on the production server when deploying the Node.js app , thus I have tried to install the dependencies by executing npm install moduleDep --save , but I am getting the following error:

0 info it worked if it ends with ok 1 verbose cli [ 'node', '/usr/local/bin/npm', 'install', 'jquery', '--save' ] 2 info using npm@1.2.2 3 info using node@v0.8.18 4 verbose read json /home/roth/develop/build/package.json 5 error Error: invalid version: 1 5 error at validVersion (/usr/local/lib/node_modules/npm/node_modules/read-package-json/read-json.js:582:40) 5 error at final (/usr/local/lib/node_modules/npm/node_modules/read-package-json/read-json.js:342:23) 5 error at /usr/local/lib/node_modules/npm/node_modules/read-package-json/read-json.js:140:33 5 error at cb (/usr/local/lib/node_modules/npm/node_modules/slide/lib/async-map.js:48:11) 5 error at /usr/local/lib/node_modules/npm/node_modules/read-package-json/read-json.js:320:48 5 error at fs.js:117:20 5 error at /usr/local/lib/node_modules/npm/node_modules/graceful-fs/graceful-fs.js:53:5 5 error at /usr/local/lib/node_modules/npm/node_modules/graceful-fs/graceful-fs.js:62:5 5 error at Object.oncomplete (fs.js:297:15) 6 error If you need help, you may report this log at: 6 error <http://github.com/isaacs/npm/issues> 6 error or email it to: 6 error <npm-@googlegroups.com> 7 error System linux 3.1.10-1.16-desktop 8 error command "node" "/usr/local/bin/npm" "install" "jquery" "--save" 9 error cwd /home/roth/develop/build 10 error node -v v0.8.18 11 error npm -v 1.2.2 12 verbose exit [ 1, true ]

Before I can run the main module, I have to use NPM for installing the dependencies. Is there any command which I can execute that will install and then add the dependency to the package.json ? A thorough explanation will be great.
