Javascript 未在反射元数据-\uuuu网页\uu Require\uuuu问题上定义Require

我正试图在visual studio上启动我的angular应用程序，但当它启动时，它在加载时会出现问题。。。节

如果我阅读Chrome的错误控制台，我会得到以下错误：

未捕获引用错误：未在对象上定义require匿名>\uuuuuuuuuuuuuuuuuuu需要的网页__

反射元数据包含以下内容：module.exports=requirereflect元数据，这会导致错误

这是我的一些代码

webpack.config.js

在互联网上搜索时，所有的故障排除都建议在systemjs.config文件上执行一些操作，但我的不是angular cli应用程序，所以我无法执行

更新部分

更新1 问题似乎是由在浏览器模式下执行的webpack节点外部导致的

必须找到另一种方法

有任何故障排除或潜在解决方案建议吗

提前谢谢

更新2 我成功了，请看下面我的答案

明白了

该问题是由在我的通用配置中使用的网页包节点外部导致的

有关更多详细信息，请参见我的问题和我对自己问题的回答

简而言之，我遵循的步骤如下：

安装requireJS==> 删除externals:[nodeExternals]，//以便从我的通用网页配置中忽略node_modules文件夹中的所有模块，并将其添加到我的服务器配置下，这是在我提出问题之前完成的，但这是一个非常重要的步骤[请参阅本答案上面链接的问题中的webpack.config.js内容或下面的代码片段] 在上面我的externals点之前，在我的问题之前完成的服务器端部分下添加target:“node”，但这是一个非常重要的步骤[请参阅本答案中上面链接的问题或下面的代码片段中的webpack.config.js内容] 这确保浏览器端保持target:“web”默认目标，并且目标仅成为服务器的节点。 从powershell webpack-config webpack.config.vendor.js手动启动webpack config vendor命令 从powershell webpack-config webpack.config.js手动启动webpack config命令 这对我有用！希望它也适用于阅读此问题和遇到此问题的任何其他人
