I'm getting the error heroku cannot find module 'Sequelize' when the server runs npm start on index.js file. When I run it locally by command heroku local it works fine. What I don't understand is that there is no module called 'Sequelize' in my project. It's called in lower case sequelize. Here's my package.json
{
"name": "anonbay",
"version": "1.0.0",
"description": "social network app",
"main": "index.js",
"scripts": {
"start": "node index.js"
},
"author": "saud",
"license": "ISC",
"dependencies": {

"body-parser": "^1.16.0",

"pg": "^6.1.2",
"pg-hstore": "^2.3.2",
"sequelize": "^3.30.4",
"subscriptions-transport-ws": "^0.6.0"
}
}
My bad I was importing 'Sequelize' with uppercase. It works locally but it seems heroku is case sensitive. Changed it to 'sequelize' and it worked

Whenever I'm trying to install koa yarn add apollo-server-koa graphql, I'm getting this error:
Couldn't find package "#koa/cors#^2.2.1" required by "apollo-server-koa" on the "npm" registry.
I tried npm instead of yarn and I got the same error.
Here is my package.json file:

Any suggestions please?
I have a project that is using express for the backend API. The project is working on my local machine but when I try to deploy it on a linux VM I get the error "Cannot find module 'Express'".
The steps I took to produce this error were cloning and cding into the repo, and running npm install. express is listed as a dependency in the package.json file. I tried explicitly running npm install express and npm install -g express and both said that they added and/or updated packages and did not return any errors. I also looked in the node_modules folder and there is an express folder there as well.
My package.json:
{
"name": "user-backend",
"version": "1.0.0",
"private": true,
"description": "",
"main": "index.js",
"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",

"slugify": "^1.3.1",

},
"devDependencies": {

}
}
Any help would be greatly appreciated. Thank you
This ended up being a simple syntax error in my import ("Express" vs "express")
To clarify the issue:
I have built a node server, which works fine. But on pushing to git and cloning elsewhere, it doesn't work in the new location.
Cleared node_modules, and tried npm install.
gitignore has only node_modules directory in it.
package.json contains the following
{
"name": "node-todo-api",
"version": "1.0.0",
"description": "",
"main": "index.js",
"scripts": {
"start": "node server/server.js",
"test": "export NODE_ENV=test || SET NODE_ENV=test && mocha server/**/*.test.js",
"test-watch": "nodemon --exec 'npm test'"
},
"engines": {
"node": "6.2.2"
},

"lodash": "^4.15.0",
"mongodb": "^2.2.5",
"mongoose": "^4.5.9",
"validator": "^5.6.0"
},
"devDependencies": {
"expect": "^1.20.2",

"nodemon": "^1.10.2",
"supertest": "^3.1.0"
}
}
I have an application that's running fine locally, but cannot run when deployed.
The message is
Error: Cannot find module 'jsonwebtoken'
even though I have it in "dependencies" in my package.json (not devdependency)
I tried "heroku run bash" and verified that jsonwebtoken exists in the node_modules folder.
Finally I tried "heroku local web" and it works fine.
But for some reason it never works when deployed.
This is the start of the file that needs jsonwebtoken
var mongoose = require('mongoose');
var crypto = require('crypto');
console.log('check1');
var jwt = require('jsonwebtoken');
console.log('check2');
It gets to "check1" but not "check2"
This is my package.json
{
"name": "loc8r",
"version": "0.0.1",
"private": true,
"scripts": {
"start": "node ./bin/www"
},
"engines": {

}
Can someone please help me figure out what's going on?
The node version you are using on Heroku is too old judging from the package.json of jsonwebtoken. I would suggest upgrading to the latest version.
I'm pretty sure it works locally for you because you are running a newer version than 0.10.X on your own computer.
I need some help, i'm trying to add mongoose to my openshift v3 env but can't find how.
already try to use package.json.
Edit :
deploy log
package.json
