从Angular 8升级到Angular 9的问题

angularnpmpackage.jsonangular9

我正在按照Angular官方更新指南中的步骤进行操作，但我遇到了一个问题，当我尝试查找解决方法时，没有得到太多有用的结果。
在更新完成后，我看到以下输出：
Your project has been updated to Angular version 9!
For more info, please see: https://v9.angular.io/guide/updating-to-version-9

当我运行ng serve时，会得到以下输出：
Schema validation failed with the following errors:
  Data path ".browserTarget" should match pattern "^[^:\s]+:[^:\s]+(:[^\s]+)?$".

在angular.json文件中，我的服务配置如下：
    "serve": {
      "builder": "@angular-devkit/build-angular:dev-server",
      "options": {
        "browserTarget": "My Application:build"
      },

这是我在 package.json 中的依赖项和开发环境依赖项：

在angular.json中删除项目名称中的空格，并更新所有对该项目名称的引用。因此，将“我的应用程序”替换为“MyApplication”（只使用JavaScript标识符有效的字符，“空格”不是其中之一）。

...
  "projects": {
    "MyApplication": {
      "projectType": "application",

...

        "serve": {
          "builder": "@angular-devkit/build-angular:dev-server",
          "options": {
            "browserTarget": "MyApplication:build"
          },
          "configurations": {
            "production": {
              "browserTarget": "MyApplication:build:production"
            }
          }
...

  "defaultProject": "MyApplication"

etc...

尝试避免应用程序名称中的空格。在您的情况下，修改My Application:build --> MyApplication:build的serve.options.browserTarget，并再次尝试。
这对我没有任何影响。 - rustyshackleford
