Question

我向Heroku部署了两个nodejs项目，每个项目位于自己的文件夹中 -
NodejsExpressApp1和NodejsConsoleApp1。

我已向应用根添加了Procfile文件，其中包含以下内容 -
web: node NodejsExpressApp1/app.js
worker: node NodejsConsoleApp1/app.js

此外，我已将BUILD_DIR config var设置为NodejsExpressApp1文件夹。

本地一切正常。

下面显示了我在部署时获得的内容 -

c:\ExpressMultiProjectApp2>git push heroku master

谢谢！

在app root中创建package.json文件后修复了该问题 -

{
    "name": "nodejs-express-app1",
    "version": "0.0.0",
    "description": "Multiple Buildpacks App",
    "author": { "name": "SimonBor" },
    "dependencies": {
        "express": "~4.9.0"
    }
}

设置变量BUILD_DIR不是必需的步骤。

当然，这不是最佳实践解决方案，但它允许我继续开发我会更乐意寻求更好的解决方案。

祝你好运！
