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.
官方文档
https://react.dev/reference/react/useCallback解决方案
-
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. -
If using webpack, add an alias for 'react' in webpack.config.js: `resolve: { alias: { react: path.resolve('./node_modules/react') } }` to force correct resolution. -
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:
-
95% 失败
The error is about React object being null, not strict mode.
-
90% 失败
The issue is with module resolution, not JSX structure.
-
80% 失败
The error stems from bundler misconfiguration, not corrupted packages.
