Solution 1

I had the same problem and I changed the version of react-redux to 6.0.1 instead of using a more recent one, and the issue was resolved.

Please change version by running following command:

npm install [email protected].

My project version is greater than 16.5.0 but I am unsure if this also has an impact or not.

Solution 2

Had this exact same error. Realised it's not due to syntax errors, but the react-redux version compabitility. Once I ran yarn check, it gave me multiple messages that "react-redux#react@^16.8.4 does not satisfy found match of [email protected]".

Expo is react 16.5.0 while react-redux expects react version 16.8.4 . As moi answered, installing react-redux 6.0.0 worked for me. Trying to change any other package caused even more errors to appear

Solution 3

Try using react 16.6.0 instead of 16.5.0

Solution 4

This is issue with expo.Try to clear expo cache by using this command

expo r -c

Solution 5

Try update your dependencies.

I have the same problem and I'm using npm-check-updates.

Here's a update check log:

 expo               ^32.0.0  →  ^32.0.6
 react               16.5.0  →   16.8.6
 react-navigation    ^3.6.1  →   ^3.7.1
 babel-preset-expo   ^5.0.0  →   ^5.1.1

Run npm install to install new versions.

I get this the error

_react.default.memo is not a function

and wrapWithConnect.
This is a react-native project and it worked fine before I used the connect function to connect my dispatch into my react component:

Package Versions:

    "react": "16.5.0",
    "react-redux": "^6.0.1",
    "redux": "^4.0.1",
    "redux-logger": "^3.0.6",
    "redux-thunk": "^2.3.0",

code

const mapDispatchToProps = dispatch => {
 return { 
  sendEmail: (email, navigateMap) => dispatch(sendEmail, navigateMap))

export default connect(null, mapDispatchToProps)(Login)
