将角度 9 更新为 11 时出现许多错误

Question

我在上周四开始了 Angular 更新，不幸的是，从那时起我一直在努力，但出现了很多错误。 运行 ng serve -o 的最新错误是：

An unhandled exception occurred: ENOENT: no such file or directory, lstat 'C:\dev\code\UI\trunk\MindoLifeDashboard\node_modules\angular-archwizard\archwizard.css'
See "C:\Users\Rami\AppData\Local\Temp\ng-cPGeAU\angular-errors.log" for further details.

已安装的版本：

ng --version

我尝试安装缺少的软件包，但它并没有从警告中消失。

任何提示???

Answer 1

这些警告是因为您的某些直接依赖项需要特定版本的对等库，并且您安装的这些库的版本比所需的版本新。

例如，您收到警告

npm WARN @angular/compiler-cli@11.2.6 requires a peer of typescript@>=4.0 <4.2 but none is installed. 

因为您安装了 typescript 4.2.3。您可以明确安装可接受的版本，例如npm install typescript@4.1 或者可能只是忽略警告，只要为每个生成警告的依赖项安装了比要求更新的版本。

更大的问题是错误。如果您还没有安装 angular-archwizard 库，我猜您需要安装它，或者安装更新的版本？
