安裝“single-spa”后出現錯誤，無法理解問題

Question

在我將 angular 從 8 升級到 9 后，我實現了single-spa 。當我通過運行命令yarn serve:single-spa:ibo開始運行應用程序時，出現以下錯誤。

$ ng s --project ibo --disable-host-check --port 4200 --deploy-url http://localhost:4200/ --live-reload false
As a forewarning, we are moving the CLI npm package to "@angular/cli" with the next release,
which will only support Node 6.9 and greater. This package will be officially deprecated
shortly after.

To disable this warning use "ng set --global warnings.packageDeprecation=false".

The option '--project' is not registered with the serve command. Run `ng serve --help` for a list of supported options.
The option '--disable-host-check' is not registered with the serve command. Run `ng serve --help` for a list of supported options.
Cannot read property 'config' of null

無法理解問題。 有人請幫幫我嗎？ 這是我的angular.json文件：

Answer 1

在ng --version之后，您應該看到如下內容

Your global Angular CLI version (10.0.0-next.6) is greater than your local
version (9.1.6). The local Angular CLI version is used.

按照說明安裝最新的穩定 angular/cli

這取決於您擁有的舊版本，請嘗試如下

npm uninstall -g angular-cli
npm uninstall -g @angular/cli
npm install -g @angular/cli@latest 

ng --version不僅應該給出單行，而且應該如下

Angular CLI: 9.1.6
Node: 10.16.0
OS: win32 x64

Angular: 9.1.7
... animations, common, compiler, compiler-cli, core, forms
... language-service, platform-browser, platform-browser-dynamic
... router
