模块未找到:错误:无法解析'/home/dell/Desktop/Coding/photography/photo-gallery/node_modules/jwa‘中的“密码”

Question

我正在使用React，我正在MERN堆栈中构建一个简单的管理登录页面，并使用npm包: jsonwebtoken、router、@material/图标。我不断地犯错误：

ERROR in ./node_modules/jwa/index.js 5:13-30

Module not found: Error: Can't resolve 'crypto' in '/home/dell/Desktop/Coding/photography/photo-gallery/node_modules/jwa'

BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.

If you want to include a polyfill, you need to:
    - add a fallback 'resolve.fallback: { "crypto": require.resolve("crypto-browserify") }'
    - install 'crypto-browserify'
If you don't want to include a polyfill, you can use an empty module like this:
    resolve.fallback: { "crypto": false }

Answer 1

类似于this问题，您需要找到webpack配置，添加回退配置和npm install crypto-browserify。
