为什么 Bootstrap 不能与 Angular 一起使用？

Question

我安装了 Bootstrap 和 jQuery。我在 angular.json 中添加了 js 和 css 路径。我退出并再次运行服务器，但引导程序仍然无法正常工作。你能帮我解决这个问题吗？

这是表单和一些按钮，但引导程序不起作用。

当我运行服务器时，我意识到styles.js 丢失了。我不确定是不是问题！？而且不知道怎么解决

这是我运行 Angular 服务器的时间：

chunk {main} main.js, main.js.map (main) 18.8 kB [initial] [rendered]
chunk {polyfills} polyfills.js, polyfills.js.map (polyfills) 141 kB [initial] [rendered]
chunk {runtime} runtime.js, runtime.js.map (runtime) 6.15 kB [entry] [rendered]
chunk {styles} styles.js, styles.js.map (styles) 12.5 kB [initial] [rendered]
chunk {vendor} vendor.js, vendor.js.map (vendor) 2.62 MB [initial] [rendered]

我猜问题是你放了：

      "styles": [
          "node_modules/bootstrap/dist/css/bootstrap.min.css",
          "src/styles.css"
          
        ],
        "scripts": [
          
          "node_modules/jquery/dist/jquery.min.js",
          "node_modules/bootstrap/dist/js/bootstrap.min.js"
        ]

在"test" 项目下，您应该将它放在您的"build" 选项中。
