如何禁用ExtDeprecationWarning烧瓶中的外部库

问题描述

当我运行我的脚本，我得到这个输出：

  /app/venv/lib/python2.7/site -packages / flask / exthook.py：71：ExtDeprecationWarning：不推荐使用导入flask.ext.sqlalchemy，而改用flask_sqlalchemy。 
 .format（x = modname），ExtDeprecationWarning

我并不关心这个，因为外部库引起了这一点。我无法更新这些库，因为我不拥有它们，我看到有几个请求挂起请求。

我该如何获得一些安静和平静？ / p>

解决方案

首先，您应该关心这个问题，因为您使用的软件包不符合要求日期。报告应该切换到使用直接导入名称的错误，例如 flask_sqlalchemy ，而不是 flask.ext 导入hook。

添加行来过滤掉这些警告。您可以将其放置在您配置应用程序的任何地方，然后再执行任何可能引发警告的导入。

$ b from flask.exthook import ExtDeprecationWarning
$ b $ warnings.simplefilter（'ignore'，ExtDeprecationWarning）

When I run my script, I get this output:

/app/venv/lib/python2.7/site-packages/flask/exthook.py:71: ExtDeprecationWarning: Importing flask.ext.sqlalchemy is deprecated, use flask_sqlalchemy instead.

I don't really care about this, because external libs are causing this. I can't update these libs as I don't own them and I see for several there are pull requests pending.

How can I get some peace and quiet?

解决方案

First, you should care about this because the packages you're using aren't up to date. Report a bug that they should switch to using direct import names, such as flask_sqlalchemy, rather than the flask.ext import hook.

Add a warnings.simplefilter line to filter out these warnings. You can place it wherever you're configuring your application, before performing any imports that would raise the warning.

import warnings
from flask.exthook import ExtDeprecationWarning

warnings.simplefilter('ignore', ExtDeprecationWarning)
