我在AWS Elastic Beanstalk上部署Flask应用程序时，遇到了一个表面上很简单的错误，已经有一段时间了。启动应用程序会出现502 Bad Gateway错误。日志中的回溯显示：
Traceback (most recent call last):

ModuleNotFoundError: No module named 'application'
我在application.py中的烧瓶应用程序非常简单：
from flask import Flask
from flask import render_template
application = app = Flask(__name__)
if __name__ == "__main__":
application.run()
@application.route("/")
def index():
return render_template('index.html', name=None)
我的目录结构也是如此。我上传ball.zip，其中包含：
ball/
application.py
requirements.txt
static/
templates/
该应用程序使用在64位AmazonLinux2/3.3.9上运行的Python 3.7。我还检查了配置变量WSGIPath是否设置为application。有人对解决这个问题有什么建议吗？谢谢
您不应该有文件夹"球；在你的拉链里。每个文件都应该在zip的根目录中，而不是在文件夹"中；球"；。
