python - 导入时 Boto3 弃用警告

Question

我正在尝试在 python/django 项目中使用 boto3。我以前做过这个，但它在运行 localhost 时向我发出警告——这破坏了我试图运行的请求。我在使用 python 3.7 版。我已经看到在 boto3 的 GitHub 存储库中提出的问题，大多数指的是运行 pytest 时的错误。我的issue好像和最新的PR不符

我不太确定该转向哪里。非常感谢任何建议。

    from . import urllib3
  File "/Users/neilballard/.local/share/virtualenvs/Volley-ldVCpc8_/lib/python3.7/site-packages/botocore/vendored/requests/packages/urllib3/__init__.py", line 10, in <module>
    from .connectionpool import (

    from .response import HTTPResponse

DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working

我已经确认是“import boto3”引起了这个问题。我删除了 boto3，重新安装，尝试了不同版本的 boto3 和 urllib。

我用这个代码序列隐藏了警告:

try:
    import botocore
    import boto3
except ImportError:
    print("No module named botocore or boto3. You may need to install boto3")
    sys.exit(1)

boto3.compat.filter_python_deprecation_warnings()
