我希望你们一切都好。我有这个问题:在尝试修复之前的错误(Uncaught Error: Module build failed (from ./node_modules/source-map-loader/dist/cjs.js))之后，我最终使用npm来处理它。但在此之后，我在控制台中看到了一个错误：path.js:25 Uncaught ReferenceError: process is not defined  此错误位于以下位置：  我的依赖关系是：   控制台错误： [1] WARNING in ./node_modules/express/lib/view.js 74:13-25 [1] Critical dependency: the request of a dependency is an expression [1] @ ./node_modules/express/lib/application.js 26:11-28 [1] @ ./node_modules/express/lib/express.js 19:12-36 [1] @ ./node_modules/express/index.js 10:0-41 [1] @ ./src/pages/LogIn.js 6:0-35 [1] @ ./src/App.js 8:0-34 34:40-45 [1] @ ./src/index.js 9:0-24 15:35-38 [1] [1] 1 warning has detailed information that is not shown.
