AWS Elasticbeanstalk 部署 flask 应用程序中的错误

Question

我正在使用具有 requirements.txt 文件的 EB CLI 部署 Flask 应用程序。

eb init
eb open flask-env

应用程序已正确上传到服务器上，但它的健康状态显示为严重。
我收到以下错误。

• 在仪表板中

Command failed on all instances.
ELB health is failing or not available for all instances

Application deployment failed at 2020-07-01T03:49:21Z with exit status 1 and error: Engine execution has encountered an error.
Instance ELB health state has been "OutOfService" for 14 minutes: Instance has failed at least the UnhealthyThreshold number of health checks consecutively.

• 在日志中

[ERROR] An error occurred during execution of command [app-deploy] - [InstallDependency]. Stop running the command.

Stderr:Creating a Pipfile for this project…

我还部署了多个应用程序，但它们也给出了相同的错误

删除您的 requirements.txt 文件并重新生成，但这次将您的 requirements.txt 文件保存为 UTF-8 文件。
