如何摆脱 BeautifulSoup 用户警告? [英] How to get rid of BeautifulSoup user warning?

问题描述

安装 BeautifulSoup 后，每当我在 cmd 中运行 Python 时，都会出现此警告.

After I installed BeautifulSoup, Whenever I run my Python in cmd, this warning comes out.

D:Applicationpythonlibsite-packageseautifulsoup4-4.4.1-py3.4.eggs4\__init__.py:166:
UserWarning: No parser was explicitly specified, so I'm using the best
available HTML parser for this system ("html.parser"). This usually isn't a
problem, but if you run this code on another system, or in a different
virtual environment, it may use a different parser and behave differently.

To get rid of this warning, change this:

 BeautifulSoup([your markup])

to this:

 BeautifulSoup([your markup], "html.parser")

我不知道它为什么会出现以及如何解决它.

I have no ideal why it comes out and how to solve it.

推荐答案

错误消息中明确说明了问题的解决方案.像下面这样的代码没有指定 XML/HTML/等.解析器.

The solution to your problem is clearly stated in the error message. Code like the below does not specify an XML/HTML/etc. parser.

BeautifulSoup( ... )

为了修复错误，您需要指定要使用的解析器，如下所示:

In order to fix the error, you'll need to specify which parser you'd like to use, like so:

BeautifulSoup( ..., "html.parser" )

如果您愿意，您也可以安装第 3 方解析器.

You can also install a 3rd party parser if you'd like.
