反应原生。 错误：无效的挂钩调用。 钩子只能在 function 组件的主体内部调用

Question

My App was working fine and suddenly i got this error.

Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:

1. You might have mismatching versions of React and the renderer (such as React DOM)

2. You might be breaking the Rules of Hooks

3. You might have more than one copy of React in the same app See https://reactjs.org/link/invalid-hook-call for tips about how to debug and fix this problem.

    import { useContext } from "react"; import jwtDecode from "jwt-decode"; import AuthContext from "./context"; import authStorage from "./storage"; const useAuth = () => { const { user, setUser } = useContext(AuthContext); const logIn = (authToken) => { const user = jwtDecode(authToken); setUser(user); authStorage.storeToken(authToken); }; const logOut = () => { setUser(null); authStorage.removeToken(); }; return { user, logIn, logOut }; }; export default useAuth;

All looks fine. except maybe actually importing React

import React, { useContext } from "react";

I know you don't need this for React from React 17, but there's no official statement from react native saying they use the new JSX compiler that doesn't require the import statement

also check the AuthContext file you imported
