"React.createContext is not a function" - but I am not using it - reactjs

Question

I am getting "React.createContext is not a function" error while running a react-native application. I searched for 'createContent' in the code, it doesn't exist.
Any idea what may be the reason for the error.
It is an iOS build of an app that is already running on android.
Here is my package.json file:

Answer 1

In your package react and react-dom are not having the same version which is why you get the error. react-dom#16.4.0 will want to have access to React.createContext but react#16.2.0 won't have it.
In order make it work run the following command:
yarn upgrade react#16.4.0
Or if you are using NPM:
npm install react#16.4.0

Answer 2

If this is happening using react 18 or Next JS 13. You are probably trying to use a client component functionalities in a server component. By default all components are treated as server components unless you explicitly specify.
To solve this and add the "use client" directive at the top of the file (before any imports). Here is more details on When to use Server vs. Client Components?

Answer 3

Try upgrading React to React to 16.4.1

Answer 4

Using npm I solved it by upgrading to 16.4.1:
npm i react#16.4.1

Answer 5

Adding #emotion/react resulted in a similar error TypeError: React.createContext is not a function. The error disappeared after I removed #emotion/react and downgraded #emotion/styled from 11 to 10.

Answer 6

run
npm install react#latest
and
npm install react-dom#latest
fixed my error with this update.

Answer 7

If npm i react#latest react-dom#latest doesn't work try doing npm update , it will update all packages.
