【中文标题】基本角度应用程序无法运行，错误模块构建失败：找不到模块../@angular-devkit/src/babel/X【英文标题】：Basic angular app fails to run, Error module build failed : cannot find module ../@angular-devkit/src/babel/X 【发布时间】：2021-11-03 07:08:10 【问题描述】：

我是 Angular 新手，正在按照文档构建一个基本应用程序。

节点 - v14.7.3 npm - 7.22.0 角 CLI：12.2.4 操作系统：win32 x64 @angular-devkit/architect 0.1202.4 @angular-devkit/build-angular 12.2.4 @angular-devkit/core 12.2.4 @angular-devkit/schematics 12.2.4 @schematics/角度 12.2.4 rxjs 6.6.7 打字稿 4.3.5

到目前为止，我所做的只是

npm install @angular/cli

后跟ng new firstApp

和ng serve

以下是我收到的错误，

√ Browser application bundle generation complete.

Error: node_modules/@angular/platform-browser/platform-browser.d.ts:45:22 - error NG6002: Appears in the NgModule.imports of AppModule, but could not be resolved to an NgModule class.

This likely means that the library (@angular/platform-browser) which declares BrowserModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

45 export declare class BrowserModule

我已尝试以下方法来解决此问题，

尝试删除 node_modules，删除 packacge-lock，清除 npm 缓存，最后安装 npm，这种方法已经解决了许多以前的堆栈溢出问题，但对我来说问题仍然存在。我尝试安装不同版本的 angular-cli，尝试将它们与不同节点版本和不同 npm 版本的兼容性匹配，但是由于多个损坏的依赖关系，我无法正确执行。

请提出一些解决方案，谢谢

【问题讨论】：

【参考方案1】：

我遇到了和你一样的问题，虽然很奇怪，但问题是你的文件路径上的# 符号（例如F:\#Development）。

我将 Angular 应用程序移动到另一个不包含 # 的路径，并且不再产生错误。

【讨论】：

观察力不错。过去两天我一直面临一个问题。 # in path 是根本原因。非常感谢你非常感谢！！！我无法弄清楚为什么 1 个项目正在运行，但我在不同文件夹中尝试的每个新项目都有这个问题。有谁知道错误在哪里？这浪费了我很多时间。我换了笔记本电脑，忘记了这个问题，我切换回以前的笔记本电脑并尝试创建一个基本的模板 react 应用程序，但发现同样的问题，但使用 react 的 html-webpack-plugin/库/加载器.js。伙计，您的解决方案确实起到了很好的观察作用。【参考方案2】：

尝试单独安装这些模块npm install:

npm i @angular-devkit/build-angular

npm i @ngtools/webpack

npm i mini-css-extract-plugin

npm i postcss-loader

【讨论】：

以上是关于基本角度应用程序无法运行，错误模块构建失败：找不到模块../@angular-devkit/src/babel/X的主要内容，如果未能解决你的问题，请参考以下文章
