Question

当我开始我的Angular应用程序ng serve

Webpack：编译失败。

chunk {main} main.bundle.js (main) 6.04 MB [initial] [rendered]

可能有一些想法来解决它？

我尝试将selenium webdriver安装到依赖项，但它对我没有帮助。

这个问题是因为旧版本的打字稿。转到项目目录中的package.json，将typescript版本更改为2.3.0或更高版本。然后执行命令“npm install”，然后尝试执行“npm start”。有关更详细的错误，您可以使用“tsc -p src /”
