如何为 react 和 django 应用程序编写 bitbucket-pipelines.yml 以部署在 heroku 上

如何解决如何为 react 和 django 应用程序编写 bitbucket-pipelines.yml 以部署在 heroku 上

在 bitbucket 上，我的所有构建脚本都运行良好，但是

当我在 heroku 上部署应用程序时

我收到此构建错误：

-----> Building on the Heroku-20 stack
-----> App not compatible with buildpack: https://buildpack-registry.s3.amazonaws.com/buildpacks/heroku/nodejs.tgz
    
!     ERROR: Application not supported by 'heroku/nodejs' buildpack
!     
!     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.
!     
!     If you are trying to deploy a Node.js application,ensure that this
!     file is present at the top level directory. This directory has the
!     following files:
!     
!     backend/
!     myapp/
!     db.sqlite3
!     manage.py
!     media/
!         
!     If you are trying to deploy an application written in another
!     language,you need to change the list of buildpacks set on your
!     Heroku app using the 'heroku buildpacks' command.
!         
!     For more information,refer to the following documentation:
!     https://devcenter.heroku.com/articles/buildpacks
!     https://devcenter.heroku.com/articles/nodejs-support#activation
    More info: https://devcenter.heroku.com/articles/buildpacks#detection-failure
!     Push failed

我的项目文件格式是这样的：

/backend

  /backend

  /myapp

  /media

  -manage.py

  -db.sqlite3

  -runtime.txt

  -requirements.txt


/frontend

  /src

  /node_modules

  -index.html

  -package.json

  -package-lock.json


-Procfile

-bitbucket-pipelines.yml

我的 Procfile 是：

  release: python3 backend/manage.py migrate
  web: gunicorn --chdir backend backend.wsgi --log-file -

我的 bitbucket-pipelines.yml 是：

pipelines:
default:
    - step:
        name: Backend Build
        image: python:3.8.5
        script:
        - cd backend
        - pip install -r requirements.txt
        - git archive --format=tar.gz master -o sample-app.tar.gz
        artifacts:
        - backend/sample-app.tar.gz            
    - step:
        name: Build and Test for react
        image: node:10.19.0
        trigger: manual
        caches:
        - node
        script:
        - export TRAMPOLINE_CI=true         
        - cd frontend
        - rm -rf package-lock.json
        - rm -rf node_modules
        - npm install
        - npm run build
    - step:
        name: Deploy to production
        deployment: production
        trigger: manual
        caches:
        - pip
        - node
        script:
        - pipe: atlassian/heroku-deploy:1.2.1
            variables:
            HEROKU_API_KEY: $HEROKU_API_KEY
            HEROKU_APP_NAME: $HEROKU_APP_NAME
            ZIP_FILE: backend/sample-app.tar.gz
    

我该如何解决这个错误？ 我知道我的构建应用程序没有反应文件。但我不知道如何添加它们。所以请帮助我。

这个管道代码有什么问题？

我的意思是如何将 react 和 django 应用程序部署到 heroku 上？
