reactjs - 尝试使用 Heroku 部署 Django-React 时启动脚本出错

问题描述

我正在尝试部署我的第一个应用程序，该应用程序具有 django 作为后端并为前端做出反应（使用 create-react-app）。我遵循了一些教程中的步骤，并设法让我的部署构建运行，但我收到 npm start 错误。我似乎找不到任何解决方案，任何帮助都会受到欢迎。

在我的 settings.py 我有这个：

STATIC_URL = '/static/'
STATICFILES_DIRS =[
    os.path.join(BASE_DIR,"build/static")
]

STATIC_ROOT = os.path.join(BASE_DIR,'staticfiles')
STATICFILES_STORAGE =  'whitenoise.storage.CompressedManifestStaticFilesStorage'

在 package.json 我有这些：

 "engines": {
    "node": "15.5.1",
    "npm": "6.14.11"
  }

 "scripts": {
    "dev": "react-scripts start",
    "start": "serve -s build",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject",
    "postinstall": "npm run build"
  },

我的 Procfile 看起来像这样

release:python manage.py migrate
web:gunicorn chatbot.wsgi --log-file -

标签： reactjsdjangoheroku

解决方案

该错误表明 heroku 无法启动服务器。

我想你没有安装 gunicorn 包。

  • pip 安装 gunicorn

并在 settings.py

 ALLOWED_HOSTS = ["127.0.0.1","localhost","YOUR_APP.herokuapp.com"]
