Question

我正在尝试做ng build --configuration=development，但出现以下错误：

C：\ Users \ Marina \ Desktop \ heliosFrontEnd_admin \ src \ environments \ environment.dev.ts 文件替换中的路径不存在。错误： C：\ Users \ Marina \ Desktop \ heliosFrontEnd_admin \ src \ environments \ environment.dev.ts 文件替换中的路径不存在。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.builder [作为项目] （C：\ Users \ Marina \ Desktop \ heliosFrontEnd_admin \ node_modules @ angular \ cli \ node_modules @ angular-devkit \ architect \ src \ architect.js：121：415）在MergeMapSubscriber._tryNext（C：\ Users \ Marina \ Desktop \ heliosFrontEnd_admin \ node_modules \ rxjs \ internal \ operators \ mergeMap.js：69：27）在MergeMapSubscriber._next（C：\ Users \ Marina \ Desktop \ heliosFrontEnd_admin \ node_modules \ rxjs \ internal \ operators \ mergeMap.js：59：18）在MergeMapSubscriber.Subscriber.next（C：\ Users \ Marina \ Desktop \ heliosFrontEnd_admin \ node_modules \ rxjs \ internal \ Subscriber.js：67：18）在MapSubscriber._next（C：\ Users \ Marina \ Desktop \ heliosFrontEnd_admin \ node_modules \ rxjs \ internal \ operators \ map.js：55：26）在MapSubscriber.Subscriber.next（C：\ Users \ Marina \ Desktop \ heliosFrontEnd_admin \ node_modules \ rxjs \ internal \ Subscriber.js：67：18）在TapSubscriber._next（C：\ Users \ Marina \ Desktop \ heliosFrontEnd_admin \ node_modules \ rxjs \ internal \ operators \ tap.js：65：26）在TapSubscriber.Subscriber.next（C：\ Users \ Marina \ Desktop \ heliosFrontEnd_admin \ node_modules \ rxjs \ internal \ Subscriber.js：67：18）在MergeMapSubscriber.notifyNext（C：\ Users \ Marina \ Desktop \ heliosFrontEnd_admin \ node_modules \ rxjs \ internal \ operators \ mergeMap.js：92：26）在InnerSubscriber._next（C：\ Users \ Marina \ Desktop \ heliosFrontEnd_admin \ node_modules \ rxjs \ internal \ InnerSubscriber.js：28：21）在InnerSubscriber.Subscriber.next（C：\ Users \ Marina \ Desktop \ heliosFrontEnd_admin \ node_modules \ rxjs \ internal \ Subscriber.js：67：18）在MapSubscriber._next（C：\ Users \ Marina \ Desktop \ heliosFrontEnd_admin \ node_modules \ rxjs \ internal \ operators \ map.js：55：26）在MapSubscriber.Subscriber.next（C：\ Users \ Marina \ Desktop \ heliosFrontEnd_admin \ node_modules \ rxjs \ internal \ Subscriber.js：67：18）

我的angular.json文件中有

"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": [

              "src/assets/scss/material-dashboard.scss",
              "src/assets/css/demo.css"
            ],

              "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"
                }
              ]
            },

我已经检查了路径，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"
            }
          }
        },

Ng build文件替换中的.. \ src \ environments \ environment.dev.ts路径不存在
