我正在尝试这样做，ng build --configuration=development但它给出了以下错误：

文件替换中的 C:\Users\Marina\Desktop\heliosFrontEnd_admin\src\environments\environment.dev.ts 路径不存在。错误：文件替换中的 C:\Users\Marina\Desktop\heliosFrontEnd_admin\src\environments\environment.dev.ts 路径不存在。在 Object.normalizeFileReplacements (C:\Users\Marina\Desktop\heliosFrontEnd_admin\node_modules@angular-devkit\build-angular\src\utils\normalize-file-replacements.js:25:19) 在 Object.normalizeBuilderSchema (C:\ Users\Marina\Desktop\heliosFrontEnd_admin\node_modules@angular-devkit\build-angular\src\utils\normalize-builder-schema.js:37:97) 在 BrowserBuilder.run (C:\Users\Marina\Desktop\heliosFrontEnd_admin\ node_modules@angular-devkit\build-angular\src\browser\index.js:31:33) 在 MergeMapSubscriber.getBuilderDescription.pipe.operators_1.concatMap。

在我的angular.json文件中，我有

"build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist",
            "index": "src/index.html",
            "main": "src/main.ts",
            "tsConfig": "src/tsconfig.app.json",
            "polyfills": "src/polyfills.ts",
            "assets": [
              "src/assets",
              "src/favicon.ico",
              "src/config"
            ],
            "styles": [
              "node_modules/perfect-scrollbar/css/perfect-scrollbar.css",
              "src/assets/scss/material-dashboard.scss",
              "src/assets/css/demo.css"
            ],
            "scripts": [
              "node_modules/jquery/dist/jquery.js",
              "node_modules/popper.js/dist/umd/popper.js",
              "node_modules/bootstrap-material-design/dist/js/bootstrap-material-design.min.js",
              "node_modules/arrive/src/arrive.js",
              "node_modules/moment/moment.js",
              "node_modules/perfect-scrollbar/dist/perfect-scrollbar.min.js",
              "node_modules/bootstrap-notify/bootstrap-notify.js",
              "node_modules/chartist/dist/chartist.js"
            ]
          },
          "configurations": {
            "development": {
              "fileReplacements": [
                {
                  "replace": "src/environments/environment.ts",
                  "with": "src/environments/environment.dev.ts"
                }
              ]
            },

我检查了路径，它是正确的，文件在那里。怎么了？

在“配置”之后，您必须看到“服务”。

添加开发。

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