ChristianIvicevic · 2020-11-20T11:18:45Z

You can fix this issue for the time being by downgrading to Typescript 4.0.5. It is an issue with Typescript 4.1+ being present with CRA 4.0 and may be fixed once CRA 4.0.1 is released.

dnepro · 2020-11-20T12:47:18Z

I've just had this exact error, the problem is increate-react-app\packages\react-scripts\scripts\utils\verifyTypeScriptSetup.js on Line 151 (to find it search for ts.JsxEmit.ReactJ) it was using ts.JsxEmit.ReactJsx but should use ts.JsxEmit.ReactJSX (JSX being upper case)

Thanks to @benneq this is fixed in the master branch (already three weeks ago), just needs a new patch version (see the fix: #9869).
Can somebody release a 4.0.1?

I tried that. Downgraded to TS 4.0.5 and replace "react-jsx" with "react" in the tsconfig.json jsx field.
But nothing seems to solve this.

neonise · 2020-11-20T14:54:24Z

please solve this . i have this error too.

jaquinocode · 2020-11-20T19:59:54Z

Personally, I was able to fix this issue (this is on a fresh project) by:
-changing the typescript version in package.json to "~4.0.5"
-changing the value "jsx" in compilerOptions inside tsconfig.json to "react" instead of "react-jsx"
-run npm install so that the older typescript version is installed
-I don't think this is needed but perhaps make sure vscode has the intellisense of ts set to the same or similar version to the one you've installed Mine is set to use the local one I just installed - 4.0.5
-I was then able to start the project normally with npm start

bartlettpsj · 2020-11-20T20:02:53Z

I just deleted tsconfig.json and ran yarn start, and it recreates it and runs (I did update to ts 4.0.5 too). But you have to delete everytime you run yarn start. i.e

rm tsconfig.json && yarn start

Hacky until we get a fix.

It works and the generated file is actually identical

Earle-Poole · 2020-11-20T20:28:45Z

For anyone also seeing this error.. it is already known, and a fix has been merged to master.

What we are waiting for now is a React-Scripts v4.0.1 patch on npm... no word yet on when that's happening.

The fix I am referencing: #9869

You could also comment out the line 239 in verifyTypeScriptSetup.js
if you do not want to remove your
Tsconfig file.
To find this file. You must go to node_modules/react-scripts/scripts/utils/verifyTypeScriptSetup.js

This is not a solution in any kind of production environment that uses a VCS that ignores the node_modules directory.

dyangua · 2020-11-21T03:48:23Z

Solution

Change typescript version in package.json
"typescript": "~4.0.5",

Change in tsconfig.json
"jsx": "react"

In the terminal

yarn install 
yarn start

jamesg1 · 2020-11-21T03:52:55Z

A quick solution as mentioned above 👍

yarn add typescript@4.0.5
rm tsconfig.json
yarn start

terite · 2020-11-21T04:41:52Z

Workaround for those who want to use TypeScript 4.1 and create-react-app 4.0.0: set the environment variable DISABLE_NEW_JSX_TRANSFORM to true to avoid the buggy code in verifyTypeScriptSetup.js until 4.0.1 is released.

Also, "jsx" must be set to "react" in tsconfig.json

The scripts section of my package.json now looks like this:

    "start": "env DISABLE_NEW_JSX_TRANSFORM=true react-scripts start",
    "build": "env DISABLE_NEW_JSX_TRANSFORM=true react-scripts build",
    "test": "env DISABLE_NEW_JSX_TRANSFORM=true react-scripts test",
    "eject": "env DISABLE_NEW_JSX_TRANSFORM=true react-scripts eject"

0261 · 2020-11-21T07:20:07Z

I solve this issue

"react-scripts": "4.0.0-next.98"
"typescript": "^4.1.2",

yarn start

facebook/create-react-app#10110

* Use same version of SC as in rLogin. * ignore windows debug.log file. * revert jsx setting caused by build. * Set fixed version of typescript, ref: facebook/create-react-app#10110.

The following occurred on `yarn start`: TypeError: Cannot assign to read only property 'jsx' of object '#<Object>' See: facebook/create-react-app#10110 (comment)

AveryTheDev · 2020-12-17T12:44:13Z

I see this issue with my version of TypeScript at 4.0.3 @ianschmitz

aadityarajkumawat · 2020-12-26T19:06:16Z

It seems like its fixed now with TS 4.0.3 as well

jimmy-ly · 2021-01-06T23:49:24Z

Ran into this issue as well on 4.0.0 with TS 4.1.3, updating to 4.0.1 resolved it.

RaoAkif · 2021-01-08T17:01:50Z

Just One thing:
npm install typescript@4.0.5
&
Restart the server

See facebook/create-react-app#10110

BuistvoPloti · 2021-01-27T09:32:05Z

update cra to 4.0.1 or set ts version to like "~4.0.5"

durrantm · 2021-01-28T15:13:48Z

-I was then able to start the project normally with npm start

Worked for me. Jan 28th 2020 for existing create-react-app app from 3 months ago. I tried just changing react-jsx to react but that was not enough. YOu have to change the version too and npm install Make sure you use ~4.0.5 and not ^4.0.5 as only the former works!

For me changing "react-scripts" version in package.json from "4.0.0" to "4.0.1" and running npm i fixed the error.

iampeters · 2021-03-30T07:36:58Z

Workaround for those who want to use TypeScript 4.1 and create-react-app 4.0.0: set the environment variable DISABLE_NEW_JSX_TRANSFORM to true to avoid the buggy code in verifyTypeScriptSetup.js until 4.0.1 is released.

Also, "jsx" must be set to "react" in tsconfig.json

The scripts section of my package.json now looks like this:
    "start": "env DISABLE_NEW_JSX_TRANSFORM=true react-scripts start",
    "build": "env DISABLE_NEW_JSX_TRANSFORM=true react-scripts build",
    "test": "env DISABLE_NEW_JSX_TRANSFORM=true react-scripts test",
    "eject": "env DISABLE_NEW_JSX_TRANSFORM=true react-scripts eject"

This solved it for me. thanks

Downgraded typescript due to an issue with Typescript 4.1+ being present with CRA 4.0 . For more information, check this page facebook/create-react-app#10110

I solve this error updating react-scripts to 4.0.3

yarn upgrade react-scripts@4.0.3

bseiryk · 2021-10-28T10:55:09Z

even after fix i still was getting this issue and the root cause was that my tsconfig.json had "jsx": "react". After changing to "jsx": "react-jsx" error has gone.

CauueSanttos · 2022-03-27T22:14:57Z

Solution

Change typescript version in package.json "typescript": "~4.0.5",

Change in tsconfig.json "jsx": "react"

In the terminal
yarn install 
yarn start
