TS2304: Cannot find name 'process'.

[goldenbearkin]

npm install -g create-react-app
create-react-app react-typescript --scripts-version=react-scripts-ts
cd react-typescript
npm start

I got this right away.

./src/registerServiceWorker.ts
(12,7): error TS2304: Cannot find name 'process'.

Hmm are all the typing installed? Think process should come from @types/node.

[goldenbearkin]

I think so. This is my package.json

{
  "name": "react-typescript",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@types/jest": "^20.0.2",
    "@types/node": "^8.0.4",
    "@types/react": "^15.0.33",
    "@types/react-dom": "^15.5.1",
    "react": "^15.6.1",
    "react-dom": "^15.6.1"
  },
  "devDependencies": {
    "react-scripts-ts": "2.3.1"
  },
  "scripts": {
    "start": "react-scripts-ts start",
    "build": "react-scripts-ts build",
    "test": "react-scripts-ts test --env=jsdom",
    "eject": "react-scripts-ts eject"
  }
}

Can you do npm ls --depth=0

[goldenbearkin]

sure.

➜  react-typescript npm ls --depth=0

Just tested and this is indeed not working. See there was a new release of @types/node 6 hours ago - so feel it might be related to that.

+1 Same problem here since 3 hours ago

[wmonk]

Also typescript@4 was released earlier.

[wmonk]

Yup typescript@2.4.x is the culprit. I will push a fix pinning to 2.3.x

[seyaobey]

@wmonk great job by the way! I just discovered this tool a few days ago. It has boosted my productivity...

[wmonk]

Once these go green I will publish!

[wmonk]

Fixed in 2.3.2, get from npm now! If you need to update just, npm i react-scripts-ts@latest inside your created app.

I'm seeing this with typescript 2.8.3 and @types/node 10.1.3

I had that issue and the root cause was from my tsconfig.json
adding "node" to list "compilerOptions"."types" solve the issue.

[russell-osu]

Thanks. Adding "node" to list "compilerOptions"."types" also solved the issue for me.
