Python 我该如何解决这个问题；您的requirements.txt无效。”；错误会消失吗？

我有一个用python制作的flask应用程序，正在尝试使用aws的beanstalk进行部署。我已经更新了我的requirements.txt，以包含我随pip安装的所有依赖项。我的requirements.txt文件如下所示：

Flask==0.10.1
Flask-SQLAlchemy==2.0
Flask-WTF==0.10.3
Jinja2==2.7.3
MarkupSafe==0.23
PyMySQL==0.6.3
SQLAlchemy==0.9.8
WTForms==2.0.1
Werkzeug==0.9.6
argparse==1.2.1
distribute==0.6.24
itsdangerous==0.24
wsgiref==0.1.2
boto==2.28.0
certifi==2017.4.17
chardet==3.0.3
click==6.7
idna==2.5
numpy==1.12.1
praw==4.5.1
prawcore==0.10.1
requests==2.17.3
scikit-learn==0.18.1
scipy==0.19.0
sklearn==0.0
update-checker==0.16
urllib3==1.21.1
Werkzeug==0.12.2

每当我尝试在终端中键入eb create以创建beanstalk应用程序时，我都会收到此requirements.txt错误。它还告诉我“快照”我的日志的细节，我不知道如何做。想法

作为参考，这是终端在我输入“eb create”时向我显示的全套错误消息

/var/log/eb-activity.logi中的内容我找到了这个日志文件，但它是super-super-long.tail-n 200 eb-activity.log
