我正在尝试将flask / vue应用程序部署到heroku，但是遇到了困难。
我主要遵循了这些说明（https://medium.com/the-andela-way/deploying-a-python-flask-app-to-heroku-41250bda27d0），并尝试遵循此Heroku deployment confusion: Vue.js frontend with Flask backend，但没有达到要求。
我遵循的步骤
我从test.py文件的根目录My_app_folder开始，并激活了虚拟环境“ my-venv”
然后：
我还创建并运行了以下buildpack：
heroku buildpacks:add --index 1 heroku/nodejs
然后在package.json的“脚本”中添加以下行：
"heroku-prebuild": "npm install",
"heroku-postbuild": "webpack --config webpack.dev.js"
这是我的package.json
{
"name": "sample-proj",
"version": "0.1.0",
"private": true,
"scripts": {
"serve": "vue-cli-service serve",
"build": "vue-cli-service build",

},

},

}
在我的test.py脚本中，我有：
app = Flask(__name__, static_folder = "static", template_folder = "Templates/vue_template")
这是我的应用程序的结构

我在两个地方都有package.json，因为我收到以下错误消息，并将package.json放在test.py附近解决了该错误：
The 'heroku/nodejs' buildpack is set on this application, but was unable to detect a Node.js codebase.
A Node.js app on Heroku requires a 'package.json' at the root of the directory structure.")
这些是按照上述步骤运行“ heroku logs --tail”后收到的错误消息。

我该如何解决错误，以便我可以部署我的应用？
