Joi: Can not find module 'joi' after @hapi/joi installation

Created on 6 Jun 2019 · 16Comments · Source: sideway/joi

Context

node version: 10.15.3
joi version:15.0.3
environment (node, browser): React Native 0.59 app with node/express 4.16.4 backend
used with (hapi, standalone, ...): react native 0.59 app
any other relevant information: sequelizejs 5.9.1

What are you trying to achieve or the steps to reproduce ?

Installation of @hapi/joi failed to start. Removed Joi 13.x and installed @hapi/joi with yarn add @hapi/joi. Installation finished successfully. However node index.js throws error. yarn remove the module, delete the subdir joi and @hapi/joi under node-modules and reinstall @hapi/joi, the error is the same when launching the project.

```js
const Joi = require('@hapi/joi');

Which result you had ?

internal/modules/cjs/loader.js:584
throw err;
^

What did you expect ?

Should find the Joi module without problem

Other than to remove all deps and clean cache, I don’t have other advice. It clearly works for everyone else.

Upgraded node to 10.16.0 and the error is the same.

It's likely your code is wrong, the stack trace clearly reads you explicitly require joi in your models/user.js file. I'd look that way.

I am facing the same issue. @emclab How did you resolve it?

I have the same issue

Just install this types package https://www.npmjs.com/package/@types/hapi__joi

I discovered my issue arose from having installed the most recent nodejs version (13>).

I solved it by updating npm. Run npm install -g npm.

I had the same problem and I found out that i had another dependency that required 'joi' instead of '@hapi/joi'.

How to find that "another dependency"? @thirdink

npm ls joi or yarn why joi depending on which you use.

This took me a very long time to debug. In one faraway file I had imported @hapi/Joi (notice the capital J rather than @hapi/joi (lowercase j)
