I had a similar error:

Error: Cannot find module 'sequelize/types/lib/operators'

which I found was caused by my Visual Studio Code 'helping out' by adding in:

const { substring } = require("sequelize/types/lib/operators");

I deleted this line from the top of my code, and problem went away.

Since google sent me to this similar question, I thought I would share my different solution to a different problem:

What happened?

Visual Studio Code tries to help out by automatically adding imports as you type, and when I typed this line of code:

enumSingular = enumPlural.substring(0, enumPlural.length - 1);

VS Code thought it needed to add the substring from Sequelize. I was trying to use the substring() method of the JavaScript String prototype, but I did not notice the auto-add.

Error: Cannot find module 'sequelize'

I had the same problem, but it was caused by wrong name of module.

  • correct form is: require('sequelize')
  • wrong is: require('Sequelize')

I was working on windows and trying to run code on better system ;)

hope this might be helpfull, GL

You should install sequelize and sequelize-cli with same option. Ex:

npm install -g sequelize-cli npm install -g sequelize

Looks like you install the cli in global node modules. You should also install the sequelize package along with sequelize-cli

if do it globally

npm install -g sequelize-cli
npm install -g sequelize

if do it locally 

npm install --save sequelize-cli
npm install --save sequelize

Hope it can solve your issue
