I'm working on a nodejs project for school. I wasn't able to install bcrypt with npm so i installed bcrypt-nodejs and the project worked fine yesterday. But today, when I do a "node app" i have this error :

/.../node_modules/bcrypt/node_modules/bindings/bindings.js:79
        throw e
              ^
Error: /.../node_modules/bcrypt/build/Release/bcrypt_lib.node: invalid ELF header

my package.json file looks like this:

{
  "name": "Supinfarm",
  "version": "0.0.0",
  "env": {
              "PYTHON": "/usr/bin/python2.6"
        },
  "dependencies": {
    "express": "3.1.0",
    "connect-flash": "*",
    "jade": "*",
    "stylus": "*",
    "passport": "*",
    "passport-local": "*",
    "mongoose": "*",
    "bcrypt": "*"
  }
}

I'm on Linux ubuntu 10.04 LTS I've tried to find a solution on google without success... Can somebody help me?
