TS cannot find module

[pierre-H]

Can you reproduce the problem with latest npm?

Yes

Description

When I try to import another library, I've got the error "TS : cannot find module libraryName

Environment

Run these commands in the project folder and fill in their results:

1. npm ls react-scripts (if you haven’t ejected):

C:\Users\Eytan\Documents\tickets>npm ls react-scripts
[email protected] C:\Users\Eytan\Documents\tickets
`-- (empty)

npm ERR! code 1

2. node -v: v7.3.0
3. npm -v: 3.10.10

Then, specify:

1. Operating system: Windows
2. Browser and version: Vivaldi 1.6.689.40 32bits

Reproducible Demo

yarn global add create-react-app
create-react-app my-app --scripts-version=react-scripts-ts
yarn add admin-on-rest

Then if I add this line on my code :
import { simpleRestClient, Admin, Resource } from 'admin-on-rest';

I've got the error

Sorry, this issue is about TS not react-scripts-ts.

Hi Pierre, no problem! Did you manage to sort it yourself by adding typings?

This might raise an interesting addition we could make like the eslint/taking warnings that suggests adding the typings for new packages. Could be useful if there are TS beginners using this.

I am using Yarn:

I had an error that said
cannot find name ' require'

But it still ran great (to be clear, this error ran inside atom with the atom-typescript plugin)

But this fixed it (tsconfig.json):

  "compilerOptions": {
      ...
      "types": [
        "node"
      ],
      "typeRoots": [
        "node_modules/@types"
      ]
  }

I am also having an issue with cannot find name "it", (app.test.tsx) But I am sure I will find eventually and get back with you.

I had the same problem as @CraigglesO but I managed to get around it. The only issue have is my IDE keeps telling me that cannot find name "it" even though the setup and code runs on the browser.
