编辑angular.json文件，找到下面的位置添加"baseHref":"/".

  "configurations": {
     "production": {
       "fileReplacements": [
         {
           "replace": "src/environments/environment.ts",
           "with": "src/environments/environment.prod.ts"
         }
       ],
       ...
       "baseHref": "/",
       ...
      }
  }
