在尝试安装ExcelJ（npm install --save exceljs）之前，我有一个有效的项目。
此后，我开始收到各种错误，例如Cannot read property ‘Minus’ of undefined和Cannot find module 'postcss-value-something'，可以通过npm i找出丢失的任何部分来解决。
但是，此后，我现在收到TypeError: Object prototype may only be an Object or null: undefined。
遇到这些问题后，我删除了excelJs，希望可以恢复正常，但是没有这种运气。
完整错误如下：

到目前为止，我所读过的所有地方都表明cli /编译器cli出了问题，但我印象中^表示它在必要时进行了更新，我也曾尝试删除^如果该版本超出了我项目支持的Angular版本。
ng v返回以下内容：
Angular CLI: 8.3.28
Node: 10.16.0
OS: win32 x64
Angular: 8.0.0
... animations, common, compiler, core, forms, platform-browser
... platform-browser-dynamic, platform-server, router

我怀疑这仍然与编译器/ cli版本甚至打字稿有关，正如我在其他地方看到的那样，但是似乎没有关于应该使用哪个版本的指南。
非常感谢您的协助。

您的角度软件包版本太不同步了！不知何故，您的compiler-cli位于10.0.2，但是您的http位于7.2.16。那是怎么发生的？无论如何，升级角度的最佳方法是使用ng update @angular/cli，ng update @angular/core和ng update @angular/material。
这会将其更新到版本10，并希望进行适当的迁移。以@angular开头的任何内容都应始终具有相同的主版本。您的情况是将v7与v8和v10混合使用。投入v9，您将拥有一个四重奏。
如果使用cli无法进行更新，则最好使用以下步骤：
src下的源代码以及您认为值得保存的任何其他文件，例如package.json，以检查您使用的所有非角度软件包。@angular/cli升级全局ng -g i @angular/cli@latest ng new xxx main.ts，polyfills.ts和tsconfig文件，因为最新的cli cli版本进行了重大更改package.json 此后，请始终使用ng update升级任何angular模块，因为这还包括必要的代码迁移。
请注意，如果您进行^，npm update只会更新已安装软件包的次要版本。了解更多here
