Question

我在Angular CLI中使用Angular 8。我的应用程序设置存储在environment.ts和environment.prod.ts中。 serve 和 build 命令正在使用environment.prod.ts。

我需要 serve 命令来使用environment.ts而不是environment.prod.ts。

更新：

这是我的服务命令：

ng serve

这是我的 Angular.json 文件：

Answer 1

您必须相应地编辑angular.cli.js。

"environments": {
    "dev": "environments/environment.ts",
    "prod": "environments/environment.prod.ts",
    "qa": "environments/environment.qa.ts"
  }

在发球时，您可以使用此标志传递环境。

--environment={envName}

通过阅读此article，您可以了解一个好主意。

Answer 2

您正在使用哪个

ng构建/服务

或

npm构建/提供服务

如果您使用的是“ npm”，请让您的脚本在package.json中正确

Answer 3

如果您正在使用npm start之类的服务，则由package.json中的“脚本”驱动。如果这是您启动项目的方式，请检查那里的“开始”脚本正在运行，因为它可能是用--prod标志（例如"start": "ng serve --prod",）设置的，或者引用了其他配置；除非它使用--prod标志或其他配置（例如--configuration=production）运行，否则它应该默认为environment.ts。

否则，对于angular 8，您的设置位于angular.json文件中，您应该在“项目”>“”>“建筑师”>“构建”>“配置”>“本地”下检查是否有任何fileReplacement设置，例如：

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

如果这样做，请删除“本地”的内容，使其只是空括号{}，或将“ with”值更改为"with": "src/environments/environment.ts"，然后再返回到从环境中拉取。或者，您可以完全进行全新的配置，并在构建中使用--configuration=<configuration name>标志对其进行引用（但是，如果这样做，请不要忘记在“服务”>“配置”>“”下添加“ browserTarget” （例如"<project name>:build:local"）。

Answer 4

问题是VS Code的“自动导入”功能。它自动添加了错误的路径。这是导入的行：

import { environment } from './../../environments/environment.prod';

它应该是这样的：

import { environment } from './../../environments/environment';

如果有人遇到此问题，请首先检查导入路径。

如何使serve命令使用environment.ts而不是environment.prod.ts？
