I'm trying to start using Ethereum Web3.js with 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.
Here it is my package.json
{
"name": "ethereum",
"version": "1.0.0",
"description": "",
"main": "index.js",
"dependencies": {
"ethereumjs-testrpc": "^4.0.1",
"solc": "^0.4.13",
"web3": "^1.0.0-beta2"
},
"devDependencies": {},
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1"
},
"author": "",
"license": "ISC"
}
Any Idea? Am i doing something wrong?
npm install ethereum/web3.js
should solve your problem
