Cannot find type definition file for 'node'

Question

I am getting strange errors after updating angular, webpack and typescript. Any idea what I could be missing?

When I run the app with npm start I get the following errors:

[at-loader] Cannot find type definition file for 'hammerjs'.
[at-loader] Cannot find type definition file for 'node'.
[at-loader] src\app\app.component.ts:26:14
Cannot find name 'require'.
[at-loader] src\app\app.component.ts:30:15
Cannot find name 'require'.

Answer 1

Try re-importing the @types/node package by running this in the Package Manager Console in Visual Studio:

npm i -D @types/node

If a specific version must be used, you can specify:

npm i -D @types/node@6.0.10

Answer 2

That seems more likely to be a problem of versions within the typings.json file. Can you try the following?

typings install dt~node --save
typings install dt~core-js --save
typings install dt~hammerjs --save

Answer 3

It could either be a mismatched ts-node version in which updating ts-node should fix it found here or it could be an incorrect tsconfig.json found here

If these don't work here are some links you may find useful:

Answer 4

In my case, after doing an npm update I was getting this error. It disappeared by restarting my node server :

npm start

Answer 5

You might need to apply multiple solutions to solve this issue!

STEP 1

You might need to install missing typings from @types it's already present and still you are getting this error proceed to step 2

STEP 2

If you are using ts-loader you will need to upgrade this

STEP 3 (Not applicable to all)

In some cases it's the webpack versioning which causes this error; upgrading to webpack version, ts-node, awesome-typescript-loader etc will solve it for you

STEP 4 (Angular only)

If you have used core-js upgrade its version

In general solution varies for all however its the node modules version where you will need to play around a bit! It's more of hit and try

All the best!
