Angular 6.4.1 环境构建不起作用

Question

因此，尝试执行“npm run ng build --configuration=production”并尝试让它使用我的 angular.json 中的 FileReplacements 将 environment.ts 文件替换为 environment.prod.ts
我正在使用以下版本:

"@angular/animations": "^8.0.0-beta.12",
"@angular/cdk": "~7.3.7",
"@angular/common": "^8.0.0-beta.12",
"@angular/compiler": "^8.0.0-beta.12",
"@angular/core": "^8.0.0-beta.12",
"@angular/forms": "^8.0.0-beta.13",
"@angular/material": "^7.3.7",

当我运行上面的命令来设置构建配置时，在 dist 文件夹中，我仍然看到 environment.ts 中引用的 URL，而不是 main-es5.js 文件中的 environment.prod.ts。
src/environments/environment.ts

export const environment = {
  production: false,
  baseUrl: 'http://0.0.0.0'
  
};

src/environments/environment.prod.ts

export const environment = {
  production: true,
  baseUrl: 'http://1.1.1.1'
};

如果有人看到我做错了什么，请告诉我。每次构建时都必须更改 URL 和其他变量。谢谢!

运行npm run ng build --configuration=production不会将额外的参数传递给 ng build 任务。它只会调用 ng build如果你想构建生产，你可以使用 ng build --configuration=production注意:如果你真的想使用 npm run ...要为生产构建，您需要更改感知参数的方式，如 here 所述并使用 --分开参数发送到任务

npm run ng build -- --configuration=production
