Re: [Express-js] Missing "qs" module

[dale tan]

I just installed express on a different machine, pulled down my git repo, ran `npm install -d` and ran `node-dev app.js` and `node app.js` both of which threw this error:

Error: Cannot find module 'qs'

    at Function._resolveFilename (module.js:317:11)

    at Function._load (module.js:262:25)

    at require (module.js:346:19)

    at Object.<anonymous> (/site/node_modules/connect/lib/middleware/bodyParser.js:13:10)

    at Module._compile (module.js:406:26)

    at Object..js (module.js:445:10)

    at Object..js (/usr/local/lib/node_modules/node-dev/wrapper.js:57:18)

    at Module.load (module.js:334:31)

    at Function._load (module.js:293:12)

    at require (module.js:346:19)

I'm not sure why this is happening on this one machine, but it works on two other machines i've worked with.

any clues? 

using node v0.4.9 and express 2.4.2

thanks

qs is node-querystring lib,so you can download it. and use  command "ln -s  XXX  qs.js" 
ok?

[dale tan]

is that not a package that comes default with a node install?

you mkdir ~/.node_libraries , and cd ~/.node_libraries , and use this commit ->  git clone https://github.com/visionmedia/node-querystring.git , and use ln commit like it -> ln -s node-querystring/index.js qs.js

[dale tan]

leland, i did a search for `require('qs')` (there were none w/ double quotes) and found the qs module included for connect and express.  Wouldn't this be sufficient to run the qs module since the module is only being called in that context?  I don't remember needing to install the qs module on my other two machines.

TJ, i did `npm install -d` and for some reason it didn't istall that dependency.  here is my package.json file for my project:

{

    "name": "app"

  , "version": "0.0.1"

  , "private": true

  , "dependencies": {

      "express": "2.4.2"

    , "connect": "1.5.1 < 2.0.0"

    , "connect-form": "0.2.1"

    , "connect-mongodb": "1.0.0rc2"

    , "connect-timeout": "0.0.1"

    , "dateformat": "1.0.1-1.2.3"

    , "ejs": "0.4.3"

    , "everyauth": "0.2.15"

    , "hamljs": "0.5.1"

    , "jade": ">= 0.0.1"

    , "mailer": "0.6.5"

    , "mongoose": "1.7.2"

    , "mongoose-auth": "0.0.11"

    , "node-markdown": "0.1.0"

    , "stylus": "0.13.5"

  }

}

I haven't had any issues with my other two computers and a server i use so i'm not sure why this one is causing an issue.  

Both the express module and connect module have "qs": ">= 0.0.6" listed as dependencies in their respective package.json file.

I'll check which npm version i'm using on that machine and see if that is the issue.
