当我为生产构建角度项目时，在工作区中找不到项目“生产”

Question

我是 Angular 的新手。我使用此命令ng build --target=production --base-href /，这是为生产构建角度项目时产生的错误。

Project 'production' could not be found in workspace.

Answer 1

It happened to me after upgrading from Angular 5 to Angular 6.

The solution is to replace in angular.json:

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

with:

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

so basically it's just about renaming prod to production.
