根因分析

React hooks(如 useCallback)在有效的 React 组件或自定义 Hook 上下文之外被调用,通常是由于模块打包错误或 React 导入不正确。

English

React hooks (like useCallback) are called outside a valid React component or custom hook context, often due to broken module bundling or incorrect import of React.

解决方案

  1. Ensure React is imported correctly at the top of the file: `import React, { useCallback } from 'react';` and check that your bundler (e.g., webpack) resolves 'react' to a valid module.
  2. If using webpack, add an alias for 'react' in webpack.config.js: `resolve: { alias: { react: path.resolve('./node_modules/react') } }` to force correct resolution.
  3. Check for multiple React versions in node_modules (e.g., from hoisting issues). Run `npm ls react` or `yarn why react` and deduplicate using `npm dedupe` or resolutions in package.json.

无效尝试

常见但无效的做法:

  1. 95% 失败

    The error is about React object being null, not strict mode.

  2. 90% 失败

    The issue is with module resolution, not JSX structure.

  3. 80% 失败

    The error stems from bundler misconfiguration, not corrupted packages.
