Node.js error : %1 is not a valid Win32 application

Question

Hi I downloaded a copy of my project from a running Node.js server and tried running it but encountered the following error :

Error :

E:\Projects\Smart Automation Web\Zigma_copy\automator\node_modules\bcrypt\node_modules\bindings\bindings.js:79
        throw e
              ^

How I tried to run my application :

1. I downloaded the complete app folder from my server using FTP
2. I opened the project through webstorm IDE
3. I opened its terminal and typed : npm install
4. It was success .
5. Then I typed sails lift and got the following error .

I am a novice and not able to find why it fails . Though I can read the error and it said something about my UserManager.js , so I am atatching that here too .

UserManager.js :

var jwt = require('jsonwebtoken')
var bcrypt = require('bcrypt');

var jwtSecret = "werisdkf120sdkfr84rwerf";
var ISSUER = "home-automator.com";
var EXPIRY_TIME = 120*500;

function genToken(user) {
  var token = jwt.sign({id: user.id}, jwtSecret, {issuer: ISSUER, expiresInMinutes: EXPIRY_TIME});
  return token;
}

module.exports = {
  hashPassword: function (plainTxtPassword, salt, next) {
    salt = salt || bcrypt.genSaltSync(6);
    bcrypt.hash(plainTxtPassword, salt, function (err, hash) {
      if (err) {
        return next({err: {message: "Something went wrong. Please try again later."}});
      }
      next(null, hash, salt);
    })
  },

  createUser: function (newUser, next) {
    User.findOneByEmail(newUser.email, function (err, user) {
      if (err) {
        return next({err: {message: "Failed to create user. Please try again later."}});
      }

      if (user) {
        return next({err: {message: "Email already registered. Please try a different email address."}})
      }

      User.create(newUser, function (err, user) {
        if (err) {
          return next({err: err});
        }

        next(null, user);
      })
    })
  },

  generateAuthToken: function (user) {
    return genToken(user);
  },

  generateAuthTokenFromPassword: function (username, password, next) {
    User.findOne({email: username}, function (err, user) {
      if (err) {
        return next({err: {message: "Something went wrong, please try again later."}});
      }

      if (!user) {
        return next({err: {message: "Invalid email address and/or password. Please enter valid login credentials and try again."}})
      }

      bcrypt.compare(password, user.encrypted_password, function (err, valid) {
        if (err) {
          return next({err: {message: "Something went wrong, please try again later."}});
        }
        if (!valid) {
          return next({err: {message: "Invalid email address and/or password. Please try again with valid login credentials."}});
        }
        else {
          next(null, user, genToken(user));
        }
      })
    })
  },

  getUserFromAuthToken: function (token, next) {
    jwt.verify(token, jwtSecret, {issuer: ISSUER}, function (err, user) {
      if (err) {
        return next(err);
      }

      User.findOne({id: user.id}, function (err, userData) {
        if (err) next(err);
        return next(null, userData);
      })
    })
  }
}

This is what I got after deleting node_modules and doing npm install again . Also now looks some packages are missing because of errors :

E:\Projects\Smart Automation Web\Zigma_copy\automator>npm install

Answer 1

I had this error trying to deploy on Windows too.

Delete the folder containing npm-bcrypt on the deployment server inside your project folder node_modules (..programs\server\node_modules).

On the deployment server, run:

npm install bcrypt

And it will re-install bcrypt which should solve that error for you. In addition, you will need Python >2.5 and <3.0 to properly handle fibers. If you install the latest version it likely won't work properly.
