[code-brewer]

Help~ I have try many times but got same error!

I install by use follow comomand： npm install --save request npm install --save request-promise

My javascript file content is:

_var request = require('request-promise')

var options = {
    method: 'POST',
    uri: 'http://localhost:50001',
    body: {
        "jsonrpc": "2.0",
        "method": "eth_blockNumber",
        "params": [],
        "id": 3
    },
    json: true 
}

request(options)
    .then(function (response) {
      console.log("Got: ", response)
    })
    .catch(function (err) {
      console.log("err: ", err)
    })

Then，run: node "myProjectPathXXX/use_http_promise.js" module.js:549 throw err; ^

From package.json I saw version ： "request": "^2.87.0", "request-promise": "^4.2.2"

I am actually a bit puzzled as of why the code can’t be found. It should be installed automatically by npm with request-promise. Are you using a different package manager? Anyways...

The code you are looking for is in the request-promise-core package.

Since your question is old I assume that you found a solution or moved on. Feel free to reopen if you still need a fix.
