Angular 11 没有运行 ngcc

Question

我有一个旧的 Angular 应用程序，我已经从 Angular 9 升级到了 Angular 11。(从 Angular 2 开始，这些年来它有许多稳定的升级)
我的问题是，ngcc没有运行 ng build :

$ ng build
    'node-sass' usage is deprecated and will be removed in a future major version. To opt-out of the deprecated behaviour and start using 'sass' uninstall 'node-sass'.
✔ Browser application bundle generation complete.

Error: node_modules/ngx-device-detector/index.d.ts:3:23 - error TS2314: Generic type 'ModuleWithProviders<T>' requires 1 type argument(s).

3     static forRoot(): ModuleWithProviders;
                        ~~~~~~~~~~~~~~~~~~~
node_modules/@ngx-translate/core/public_api.d.ts:22:53 - error TS2314: Generic type 'ModuleWithProviders<T>' requires 1 type argument(s).

22     static forRoot(config?: TranslateModuleConfig): ModuleWithProviders;
                                                       ~~~~~~~~~~~~~~~~~~~
node_modules/@ngx-translate/core/public_api.d.ts:26:54 - error TS2314: Generic type 'ModuleWithProviders<T>' requires 1 type argument(s).

26     static forChild(config?: TranslateModuleConfig): ModuleWithProviders;
                                                        ~~~~~~~~~~~~~~~~~~~

我真的很需要它，正如你所看到的，有些软件包有 old dependency issues ngcc可以解决。我认为当我们使用 Ivy 时，运行它将成为 build 的一部分。默认情况下。我能够手动运行命令 npx ngcc :

forest@forest:~/....$ npx ngcc
Compiling @angular/core : fesm2015 as esm2015
Compiling @angular/animations : fesm2015 as esm2015
Compiling @angular/compiler/testing : fesm2015 as esm2015
Compiling @angular/animations : esm2015 as esm2015
Compiling @angular/animations : main as umd
Compiling @angular/compiler/testing : esm2015 as esm2015
Compiling @angular/compiler/testing : main as umd
Compiling @angular/common : fesm2015 as esm2015

Compiling @angular/common/http : fesm2015 as esm2015
Compiling @angular/forms : fesm2015 as esm2015

...

之后应用程序按预期运行:

ng build

可能有什么东西阻止了它，但我找不到根本原因。任何想法可能是什么问题？

Answer 1

你可以试试:

将这些命令添加到 package.json在脚本中:

  {
    "scripts": {
      // ...
      "ngcc": "ngcc --properties es2015 browser main module --async false --first-only",
     "postinstall": "npm run ngcc",
   }
 }

删除 node_modules 文件夹，然后再次安装依赖项。

run rm -fr node_modules and then npm install.

如果你使用 CI，这个例子是一个想法，否则你可以使用 "postinstall":"ngcc" Ivy and Universal / App shell
