Elastic Beanstalk Flask 应用程序 - 没有名为“pandas_datareader”的模块

Question

我正在使用 web 服务器应用程序和 Python 后端使用 Pandas Datareader

当我在 Ubuntu VM 上本地运行应用程序时，它运行正常，但是当我将其部署到 web 服务器时，我得到以下日志，据我所知，它没有看到 Z3A43B4F88325D94022C0EFA9C2FA 数据阅读器。

我尝试使用 pip install pandas-datareader 然后 pip install pandas_datareader 卸载并重新安装它。

请帮忙：）

Answer 1

什么对我有用。

pip 冻结 > requirements.txt

将应用程序部署到 AWS

检查 EB 控制台中的服务器日志以查看问题所在。 如果任何 package 出现错误，例如我的评论之一，请将其删除并重新部署

谢谢 ！！！！！！
