Web3.js returns "Cannot find module 'web3-requestManager'"

[guidosegni]

Using node 6.11.1 on a macosx

I installed web3 with the following command:

npm install web3

Then i launch this - apparently - simple node command:

Web3 = require('web3');

Well, it returns the following error:

module.js:471
    throw err;
    ^

Error: Cannot find module 'web3-requestManager'

    at Function.Module._load (module.js:438:3)

it looks like it require some module (e.g. 'web3-requestManager') that aren't installed with the package.

Any Idea? Am i doing something wrong?

how do we get "npm audit fix" not default to deprecated versions of web3?

@cosminstefanxp I had same problem with web and firebase.. this is worked for me

• remove the ^ for web3. (In package.json). Mine is like this "web3": "1.0.0-beta.37"
• delete node_modules
• delete package-lock.json
• then npm install

@Kishanjvaghela - that was it for me! My package had a github address for web3... i replaced it with your version then followed your steps and Im up. Thanks so much!
