部署Flask应用程序时，如何修复此Elastic Beanstalk错误：系统上未找到Python 3.7.0

我正在尝试使用EB CLI部署我的Flask应用程序。我收到错误“创建环境操作已完成，但有错误”。观察环境日志，服务器似乎缺少正确的Python版本

下面是EB环境详细信息、我的PIP文件、EB CLI输出和部署日志中的错误

根据评论，问题在于EB使用的是

Python3.7.6

，而OP的依赖项需要版本3.7.0

解决方案是将依赖项更改为

python3.7.6

可以找到在EB上运行的当前python版本：

64位Amazon Linux 2 v3.0.1，运行Python 3.7-Python 3.7.6

EB使用Python 3.7.6，因此也许用它代替3.7.0会有所帮助。谢谢@Marcin，这就成功了。这是在哪里记录的？我刚刚在我的EB实例上检查了它的确切python版本。如果你不介意的话，我会给你一个答案，以备将来参考。答案中还有指向EB上Python版本的链接。谢谢@Marcin，这很有用
