我通过添加.encode("utf-8")来解决这个问题。

这意味着print(soup)变成print(soup.encode("utf-8"))。

set PYTHONIOENCODING=utf-8
set PYTHONLEGACYWINDOWSSTDIO=utf-8

您可能需要也可能不需要设置第二个环境变量PYTHONLEGACYWINDOWSSTDIO。

或者，这可以在代码中完成(尽管似乎建议通过env vars来完成):

sys.stdin.reconfigure(encoding='utf-8')
sys.stdout.reconfigure(encoding='utf-8')

另外:重现这个错误有点麻烦，所以把这个也留在这里，以防你需要在你的机器上重现它:

set PYTHONIOENCODING=windows-1252
set PYTHONLEGACYWINDOWSSTDIO=windows-1252

即使是我也面临着同样的编码问题，当你试图打印它，读/写它或打开它时。正如上面提到的，如果你想打印它，添加.encoding="utf-8"会有帮助。

soup.encode(“utf - 8”)

如果您试图打开抓取的数据并可能将其写入文件，则使用(......，encoding="utf-8")打开该文件

open(filename_csv， 'w'， newline= "，encoding="utf-8") as csv:

这个问题有很多方面。最基本的问题是您希望输出到哪个字符集。您可能还必须找出输入字符集。

Printing (with either print or write) into a file with an explicit encoding="..." will translate Python's internal Unicode representation into that encoding. If the output contains characters which are not supported by that encoding, you will get an UnicodeEncodeError. For example, you can't write Russian or Chinese or Indic or Hebrew or Arabic or emoji or ... anything except a restricted set of some 200+ Western characters to a file whose encoding is "cp1252" because this limited 8-bit character set has no way to represent these characters.

基本上，任何8位字符集都会出现同样的问题，包括几乎所有的传统Windows代码页(437、850、1250、1251等)，尽管其中一些代码页除了支持或取代英语，还支持一些额外的脚本(例如，1251支持西里尔字母，所以你可以写俄语、乌克兰语、塞尔维亚语、保加利亚语等)。8位编码最多只能有256个字符代码，并且无法表示不在其中的字符。

也许现在是一个阅读Joel Spolsky的《每个软件开发人员绝对必须知道Unicode和字符集的绝对最小值》(没有借口!)的好时机。

在终端无法打印Unicode的平台上(目前只有Windows，不过如果您喜欢回溯计算，这个问题在上个千年的其他平台上也很普遍)，尝试打印Unicode字符串也会产生这个错误，或输出mojibake。如果您看到类似Héllö的内容，而不是Héllö，这是您的问题。

简而言之，你需要知道:

What is the character set of the page you scraped, or the data you received? Was it correctly scraped? Did the originator correctly identify its encoding, or are you able to otherwise obtain this information (or guess it)? Some web sites incorrectly declare a different character set than the page actually contains, some sites have incorrectly configured the connection between the web server and a back-end database. See e.g. scrape with correct character encoding (python requests + beautifulsoup) for a more detailed example with some solutions. What is the character set you want to write? If printing to the screen, is your terminal correctly configured, and is your Python interpreter configured identically? Perhaps see also How to display utf-8 in windows console

如果你在这里，可能其中一个问题的答案不是“UTF-8”。这也越来越成为网页的普遍编码，尽管以前的标准是ISO-8859-1(又名Latin-1)，最近是Windows代码页1252。

Going forward, you basically want all your textual data to be Unicode, outside of a few fringe use cases. Generally, that means UTF-8, though on Windows (or if you need Java compatibility), UTF-16 is also vaguely viable, albeit somewhat cumbersome. (There are several other Unicode serialization formats, which may be useful in specialized circumstances. UTF-32 is technically trivial, but takes up a lot more memory; UTF-7 is used in a few network protocols where 7-bit ASCII is required for transport.) Perhaps see also https://utf8everywhere.org/

当然，如果要打印到文件中，还需要使用能够正确显示该文件的工具来检查该文件。常见的引导错误是使用只显示当前选择的系统编码的工具打开文件，或者使用试图猜测编码但猜错的工具。同样，使用Windows代码页1252查看UTF-8文本时的常见症状会导致，例如，Héllö显示为Héllö。

如果字符数据的编码是未知的，就没有简单的方法来自动建立它。如果您知道文本应该表示什么，您也许可以推断出它，但这通常是一个手工过程，涉及到一些猜测。(chardet和ftfy等自动工具可以提供帮助，但它们有时也会出错。)

To establish which encoding you are looking at, it can be helpful if you can identify the individual bytes in a character which isn't displayed correctly. For example, if you are looking at H\x8ell\x9a but expect it to represent Héllö, you can look up the bytes in a translation table. I have published one such table at https://tripleee.github.io/8bit where you can see that in this example, it's probably one of the legacy Mac 8-bit character sets; with more data points, perhaps you can narrow it down to just one of them (and if not, any one of them will do in practice, since all the code points you care about map to the same Unicode characters).

Python 3 on most platforms defaults to UTF-8 for all input and output, but on Windows, this is commonly not the case. It will then instead default to the system's default encoding (still misleadingly called "ANSI code page" in some Microsoft documentation), which depends on a number of factors. On Western systems, the default encoding out of the box is commonly Windows code page 1252. (Earlier Python versions had somewhat different expectations, and in Python 2, the internal string representation was not Unicode.)

如果您在Windows上，并将UTF-8写入一个文本文件，可能会指定encoding=" UTF-8 -sig"，这将在文件的开头添加一个BOM序列。严格来说，这是不必要或不正确的，但一些Windows工具需要它来正确识别编码。

前面的几个回答建议盲目地应用某种编码，但希望这能帮助您理解为什么这通常不是正确的方法，以及如何找出(而不是猜测)要使用哪种编码。

如果您使用的是Windows，请尝试传递encoding='latin1'， encoding='iso-8859-1'或encoding='cp1252' 例子:

csv_data = pd.read_csv(csvpath,encoding='iso-8859-1')
print(print(soup.encode('iso-8859-1')))

从Python 3.7开始， 将环境变量PYTHONUTF8设置为1

下面的脚本还包括其他有用的变量，用于设置系统环境变量。

setx /m PYTHONUTF8 1
setx PATHEXT "%PATHEXT%;.PY" ; In CMD, Python file can be executed without extesnion.
setx /m PY_PYTHON 3.10 ; To set default python version for py
