"Error: Cannot find module 'botbuilder'" when trying to use BotFramework - botframework

Question

I have used npm to download package.json and npm install to install botbuilder and api-ai-recognizer, but it tells me that it cannot find botbuilder. Can someone help me?
I have done the following in my Azure Cloud Shell:
mkdir weather-bot
cd weather-bot
npm init
npm install --save botbuilder api-ai-recognizer
cd ~
touch index.js
vi index.js
var builder = require('botbuilder');
var connector = new builder.ConsoleConnector().listen();
var bot = new builder.UniversalBot(connector);
bot.dialog('/',function(session){ session.send("You said %s", session.message.text); });
After I start the node server
node index.js hi You said hi hello You said hello
I get the error "Error: Cannot find module 'botbuilder'" .

It appears you installed your npm modules in weather-bot (i.e. ~/weather-bot/node_modules), but you have put your index.js file at the root (i.e. ~/index.js). So when you are trying to run your bot, it is looking in ~/node_modules for the botbuilder module, but it's not installed there. Try moving your index.js file to your weather-bot directory and see if it works.
