我在heroku上托管了一个项目，自上次部署以来，它不使用生产环境文件变量。我已经在我的angular.json文件中配置了替换变量文件以进行生产，并且该文件过去曾经运行过，但是只是突然停止了。
这是我的angular.json文件：

I have the same issue. Used to work. What's below don't do the trick no more.
//This will be local on prod (on heroku)
if(environment.production) {
this.environmentName = "Production";
} else {
this.environmentName = "Local";
}
Configuration
"production": {
"fileReplacements": [{
"replace": "src/environments/environment.ts",
"with": "src/environments/environment.prod.ts"
}],
"optimization": true,
"outputHashing": "all",
"sourceMap": false,
"extractCss": true,
"namedChunks": false,
"aot": true,`enter code here`
"extractLicenses": true,
"vendorChunk": false,
"buildOptimizer": true,
"budgets": [{
"type": "initial",
"maximumWarning": "4mb",
"maximumError": "5mb"
}]
}

您应该做的是package.json文件中的代码，如下所示：
"scripts": {
"ng": "ng",
"start": "node server.js",
"build": "ng build",
"test": "ng test",
"lint": "ng lint",
"e2e": "ng e2e",
"postinstall": "ng build --aot --prod" <---- here
}
用以下行替换后安装：
"heroku-postbuild": ng build --configuration=production
对我来说很好，我希望你能解决这个问题。
