node.js - 将角电子与 Devextreme 相结合

问题描述

基本上，我试图将两个项目合二为一，但我在使用 webpack 时遇到了一些我不理解的错误。

我正在尝试将Angular-Electron与Devextreme Layout结合起来

我首先尝试按照此安装所有必要的依赖项，但是每当我运行以下命令时：

npx -p devextreme-cli devextreme add devextreme-angular

它会抛出以下错误：

Cannot read property 'toString' of null

因此，我尝试通过运行以下命令在单独的存储库中创建 Devextreme 项目：

npx -p devextreme-cli devextreme new angular-app app-name

并且只是复制文件/文件夹，但现在尝试npm run start在 angular-electron 应用程序中运行时出现 webpack 错误

这是我得到的错误

解决方案

我设法弄清楚了。

基本上，我在没有电子的情况下从头开始创建了一个 devextreme 应用程序。然后我在事后向它添加了电子，并 npm run start根据 angular-electron 项目的 package.json 中的内容安装了运行命令所需的所有依赖项。

然后，我将 angular-electron 存储库中的 package.json 命令与 .vscode 文件夹中的调试文件结合使用，作为调试工作的指南。
