Angular:找不到环境文件

Question

我遵循了几个教程，他们都说在某个时候"现在转到src/environments"。但是这个文件夹在我的项目中不存在!我试图删除整个项目并重新创建它，但它没有帮助。

我是这样做的。打开cmd，然后:

1. cd my_path
2. npm install -g @angular/cli
3. ng new webversion
--> Angular routing? Yes
--> Stylesheet: CSS
4. cd webversion
5. npm install bootstrap
6. npm install firebase @angular/fire

现在教程开始使用src/environments。但我没有那个文件夹。这是我的angular.json:

{
"$schema": "./node_modules/@angular/cli/lib/config/schema.json",
"version": 1,
"newProjectRoot": "projects",
"projects": {
"webversion": {
"projectType": "application",
"schematics": {},
"root": "",
"sourceRoot": "src",
"prefix": "app",
"architect": {
"build": {
"builder": "@angular-devkit/build-angular:browser",
"options": {
"outputPath": "dist/webversion",
"index": "src/index.html",
"main": "src/main.ts",
"polyfills": [
"zone.js"
],
"tsConfig": "tsconfig.app.json",
"assets": [
"src/favicon.ico",
"src/assets"
],
"styles": [
"src/styles.css"
],
"scripts": []
},
"configurations": {
"production": {
"budgets": [
{
"type": "initial",
"maximumWarning": "500kb",
"maximumError": "1mb"
},
{
"type": "anyComponentStyle",
"maximumWarning": "2kb",
"maximumError": "4kb"
}
],
"outputHashing": "all"
},
"development": {
"buildOptimizer": false,
"optimization": false,
"vendorChunk": true,
"extractLicenses": false,
"sourceMap": true,
"namedChunks": true
}
},
"defaultConfiguration": "production"
},
"serve": {
"builder": "@angular-devkit/build-angular:dev-server",
"configurations": {
"production": {
"browserTarget": "webversion:build:production"
},
"development": {
"browserTarget": "webversion:build:development"
}
},
"defaultConfiguration": "development"
},
"extract-i18n": {
"builder": "@angular-devkit/build-angular:extract-i18n",
"options": {
"browserTarget": "webversion:build"
}
},
"test": {
"builder": "@angular-devkit/build-angular:karma",
"options": {
"polyfills": [
"zone.js",
"zone.js/testing"
],
"tsConfig": "tsconfig.spec.json",
"assets": [
"src/favicon.ico",
"src/assets"
],
"styles": [
"src/styles.css"
],
"scripts": []
}
}
}
}
}
}

根据教程，它应该包含一个"参考"到环境文件夹，以及关于哪些文件将在生产模式下被替换的文件替换信息。但这两者都没有…

我错过了什么?

更新-

直接查看Angular文档配置环境特定默认值

或Angular 15 CLI在通过ng new

创建Angular项目时不会创建environments文件夹。

---

这是过时的答案，尽管您仍然可以手动创建

您必须手动创建您的环境文件。

请参见配置环境特定默认值

从Angular 15 CLI中删除是为了简化在新的独立环境中通过ng new创建的最小应用程序。他们这样做的原因是，创建和引导单个组件应该非常简单，并且需要最少的额外文件。这确实意味着旧的教程可能已经过时了。

• 创建环境目录

• 创建自定义环境

  • environment.ts
  • environment.prod.ts
  • environment.staging。ts等。

如果您需要其他配置，复制生产配置并重命名。
