当我尝试在我的项目中包含walletconnect模块时,我当前遇到了webpack问题。由于我以前没有使用过webpack,我无法自行解决此问题。由于我需要在今晚完成此项目,因此时间至关重要。如果您能帮助我解决此错误,我将非常感谢,运行"npm run dev"命令后,此错误显示在下面的跟踪中。

ERROR in ./frontend/src/components/App.js 14:11
Module parse failed: Unexpected token (14:11)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

>     return <button>Click Me</button>;

 @ ./frontend/src/index.js 1:0-34

webpack 5.12.3 compiled with 1 error in 155 ms
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! my-webpack-project@1.0.0 dev: `webpack --mode development --entry ./frontend/src/index.js --output-path ./static/frontend/main.js`
npm ERR! Exit status 1

npm ERR! Failed at the my-webpack-project@1.0.0 dev script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

正如我告诉你的,我只是想添加walletconnect功能,为此我需要使用节点模块中的walletconnect模块。

出现引用错误(未定义Webpack)
请尝试重新安装程序包
1.从项目中删除node_modules
1.运行npm install
1.运行npm install webpack
1.请重试npm run dev
也尝试添加以下行
const webpack = require('webpack'); //to access built-in plugins
在webpack.config.js的第一个
