Node.js cannot find module 'readable-stream'

问题

I am new to node.js and stuck on the following. Any help will be appreciated:

I am running node.js (0.10.28) on ubuntu (12.10). The code I am working on is:

"use strict";

var  mysql = require('node-mysql'),
connection = mysql.createConnection({
    host: "127.0.0.1",
    user: "user",
    password: "password",
    database: "dbname"
});
    if(connection) { 
    console.log("Query");
    connection.query("select * from client",function(err,res) {
    if(err)console.log(err);
    console.log(res);
});
}

I get the following error

Error: Cannot find module 'readable-stream'

I got this error for the a long while. Stupidly I hadn't installed gulp... In short this problem occurs when a package is missing.

npm install gulp -g

I would suggest working out which task you are running and then install that.

回答2:

There were many reason for this issue: I have faced this issue because I had older version of node.js related files.

Un-install the node.js
Go to your user folder like C:\Users\<uname> and find all the node.js related files and delete everything.
Install node.js freshly

It worked for me.

In my case, (windows) after uninstalling nodejs, and before reinstalling it I had to delete the folder:

C:\Program Files\nodejs\node_modules\npm

and after reinstalling node it worked like a sharm

回答4:

After grepping I found:

  $ cd /usr/lib/
  $ ack-grep readable-stream
nodejs/sha/index.js
3:var Transform = require('stream').Transform || require('readable-stream').Transform

and change that line to:

var Transform = require('stream').Transform // || require('readable-stream').Transform

and error goes out!

I was having this problem building a vue library. Deleting node_modules and re-running npm isntall and then rebuilding my lib worked.
