我的项目运行良好，直到将整个项目文件夹复制到另一台机器上，这就是我现在在新机器上得到的东西：
Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
- configuration.entry should be one of these:
function | object { <key>: non-empty string | [non-empty string] } | non-empty string | [non-empty string]
-> The entry point(s) of the compilation.
Details:
* configuration.entry should be an instance of function
-> A Function returning an entry object, an entry string, an entry array or a promise to these things.
* configuration.entry['styles'] should be a string.
-> The string is resolved to a module which is loaded upon startup.
* configuration.entry['styles'] should not contain the item 'G:\MyProjects\kud2\node_modules\ngx-bootstrap\datepicker\bs-datepicker.css' twice.
* configuration.entry should be a string.
-> An entry point without name. The string is resolved to a module which is loaded upon startup.
* configuration.entry should be an array:
[non-empty string]

我尝试重新安装webpack，但无济于事。
npm uninstall webpack --save-dev
npm install webpack --save-dev
有什么想法会导致这种情况吗？

我遇到了同样的问题，这就是我解决的方法。我在angular.json中使用了两种样式
"styles": [
"./node_modules/@angular/material/prebuilt-themes/deeppurple-amber.css",
"src/styles.css",
"node_modules/bootstrap/dist/css/bootstrap.min.css",
"src/styles.css"
],
如您所见，有两个"src/style.css"
新代码
"styles": [
"./node_modules/@angular/material/prebuilt-themes/deeppurple-amber.css",
"src/styles.css",
"node_modules/bootstrap/dist/css/bootstrap.min.css"
],

configuration.entry ['styles']不应包含该项 'G：\ MyProjects \ kud2 \ node_modules \ ngx-bootstrap \ datepicker \ bs-datepicker.css' 两次。
我在日志中看到一些重复的样式条目配置，您可以检查一下是否在项目中使用它吗？

运行命令后，我遇到了同样的问题：
ng添加ngx-bootstrap --component工具提示
这为angular.json添加了额外的“ node_modules / bootstrap / dist / css / bootstrap.min.css”引用，将其删除后已修复错误
