blocks|key|1465251|text|问题没有一个答案，正如问题中所描述的那样。有许多问题可能导致指定的错误，所以最好在PyCharm环境中解决几个可能的因素。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1465252|每个.py文件(或任何其他文件)都有一个编码。.py源代码文件的默认编码是Unicode+UTF-8。初学者经常面临这个问题，因此让我们从正式文档中找出相关的引文(以缩短任何不必要的阅读时间)：
Python的Unicode支持
Python源代码的默认编码是UTF-8，因此您可以简单地在字符串文本中包含一个Unicode字符。|ordered-list-item|offset|length|style|CODE|1465253|这意味着在大多数情况下，您不应该需要编码字符串，请参阅Python源代码编码-+PEP+263。目前的做法是默认情况下将源文件编码在UTF-8中，并在模块顶部省略编码字符串(这也更简洁)。|1465254|PyCharm+IDE有许多编码配置，可以从全局到项目，再到文件路径，依次进行细化。默认情况下，所有内容都应该设置为UTF-8，特别是源代码。请参阅正式的PyCharm文档配置文件编码设置。|1465255|以上情况的例外应该是，如果您正在处理外部数据文件，在这种情况下，您的源代码仍应保留为UTF-8，并且数据文件以它所需的任何编码方式打开。大多数关于UnicodeDecodeError的问题都是关于在使用open()函数到打开一些数据文件时指定正确的文件编码(它们不是关于编写代码的源文件的编码)。|1465256|当源文件导致此错误时，常见的原因是复制粘贴或打开后，即未在UTF-8中编码的源代码文件。(当您从未用UTF-8编码的文件中复制并且IDE不会自动将您要复制粘贴的内容转换到编辑器时，复制粘贴是特别出乎意料的)。这可能会导致上述错误。因此，您应该缩小哪个源代码文件的编码不是UTF-8，并转换它。|1465257|我们没有访问您的项目文件的权限，但我看到的错误消息是，调试器试图打开未用UTF-8编码的用户源代码文件，这与IDE配置和模块编码相反。|1465258|文件"D:\Program+\JetBrains\+2020.3.3\plugins\python-ce\helpers\pydev_pydevd_bundle\pydevd_comm.py“|blockquote|1465259|entityMap|0|LINK|mutability|MUTABLE|url|https://docs.python.org/3/howto/unicode.html#python-s-unicode-support|1|https://www.python.org/dev/peps/pep-0263|2|https://www.jetbrains.com/help/pycharm/encoding.html#file-encoding-settings|3|https://docs.python.org/3/library/functions.html#open|4|https://stackoverflow.com/search?tab=votes&q=UnicodeDecodeError^0|0|2|3|N|3|2Q|G|0|0|R|K|1|0|2E|8|2|0|21|I|2T|6|2T|6|3|32|8|4|0|0|0|0^^$0|@$1|2|3|4|5|6|7|1B|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|1C|8|@$E|1D|F|1E|G|H]|$E|1F|F|1G|G|H]]|9|@$E|1H|F|1I|1|1J]]|A|$]]|$1|I|3|J|5|6|7|1K|8|@]|9|@$E|1L|F|1M|1|1N]]|A|$]]|$1|K|3|L|5|D|7|1O|8|@]|9|@$E|1P|F|1Q|1|1R]]|A|$]]|$1|M|3|N|5|D|7|1S|8|@$E|1T|F|1U|G|H]|$E|1V|F|1W|G|H]]|9|@$E|1X|F|1Y|1|1Z]|$E|20|F|21|1|22]]|A|$]]|$1|O|3|P|5|D|7|23|8|@]|9|@]|A|$]]|$1|Q|3|R|5|6|7|24|8|@]|9|@]|A|$]]|$1|S|3|T|5|U|7|25|8|@]|9|@]|A|$]]|$1|V|3|-4|5|6|7|26|8|@]|9|@]|A|$]]]|W|$X|$5|Y|Z|10|A|$11|12]]|13|$5|Y|Z|10|A|$11|14]]|15|$5|Y|Z|10|A|$11|16]]|17|$5|Y|Z|10|A|$11|18]]|19|$5|Y|Z|10|A|$11|1A]]]]

There isn't one single answer to the problem as it is described in the question. A number of issues can cause the indicated error, so it's best to address the several possible factors in the context of the PyCharm IDE.
<ol>
<li>Every Python file <code>.py</code> (or any other file for that matter) has an encoding. The default encoding of a <code>.py</code> source code file is Unicode UTF-8. This problem is frequently faced by beginners, so lets pinpoint the relevant quotes from the official documentation (to shorten any unnecessary reading time):
<blockquote>
<a href="https://docs.python.org/3/howto/unicode.html#python-s-unicode-support" rel="nofollow noreferrer">Python’s Unicode Support</a>
The default encoding for Python source code is UTF-8, so you can simply include a Unicode character in a string literal.
</blockquote>
This means in most circumstances you shouldn't need the encoding string, see <a href="https://www.python.org/dev/peps/pep-0263" rel="nofollow noreferrer">Python Source Code Encodings - PEP 263</a>. Current practice is having the source files encoded by default in UTF-8 and omitting the encoding string at the top of the module (this is also more concise).
</li>
<li>The PyCharm IDE has a number of encoding configurations that can successively be refined, going from global, to project, to file path. By default, everything should be set to UTF-8, especially the source code. See the official PyCharm documentation <a href="https://www.jetbrains.com/help/pycharm/encoding.html#file-encoding-settings" rel="nofollow noreferrer">Configure file encoding settings</a>.
</li>
<li>The exception to the above should be if you are processing external data files, in which case your source code should still be kept as UTF-8 and the data file opened with whatever encoding it requires. Most questions about the <code>UnicodeDecodeError</code> are about specifying the right file encoding when using the <a href="https://docs.python.org/3/library/functions.html#open" rel="nofollow noreferrer"><code>open()</code></a> function to <a href="https://stackoverflow.com/search?tab=votes&amp;q=UnicodeDecodeError">open some data file</a> (they are not about the encoding of the source files where you are writing your code).
</li>
<li>When your source files cause this error, a frequent cause is after copy-pasting, or opening, a source code file that is not encoded in UTF-8. (The copy-paste is especially unexpected, when you copy from a file that isn't encoded in UTF-8 and the IDE doesn't automatically convert what you are copy-pasting into the editor). This can cause the said error. So you should narrow down which source code file has the encoding that isn't UTF-8 and convert it.
</li>
</ol>
We don't have access to your project files, but the error message to me reads as the debugger trying to open a user source code file that isn't encoded in UTF-8, contrary to the IDE configurations and module encoding.

blocks|key|1465298|text|我也遇到了同样的问题，并在更改了解释器设置中使用的python可执行文件的情况后，最终修复了它，正如解释的这里所解释的那样。长话短说，有时PyCharm尝试使用Python+(大写为"P“)而不是python来执行venv目录中的符号链接。更改后，我可以再次调试。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1465299|entityMap|0|LINK|mutability|MUTABLE|url|https://youtrack.jetbrains.com/issue/PY-14497#focus=Comments-27-5243196.0-0^0|28|6|2Q|6|2Z|4|1H|2|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@$9|O|A|P|B|C]|$9|Q|A|R|B|C]|$9|S|A|T|B|C]]|D|@$9|U|A|V|1|W]]|E|$]]|$1|F|3|-4|5|6|7|X|8|@]|D|@]|E|$]]]|G|$H|$5|I|J|K|E|$L|M]]]]

I faced the same issue and finally fixed it after changing the case of the python executable used in my interpreter settings, as explained <a href="https://youtrack.jetbrains.com/issue/PY-14497#focus=Comments-27-5243196.0-0" rel="nofollow noreferrer">here</a>. Long story short, sometimes PyCharm try to execute the symlink in the <code>venv</code> directory using <code>Python</code> (with the &quot;P&quot; in uppercase) instead of <code>python</code>. After changing this I could debug again.

Look at Stefan Ukena's answer on this thread:

Quote in case the link dies:
<blockquote>
You might need to change your Python Interpreter in the Pycharm &gt; settings. In my case (using pipenv), it was pointing to /Library/.../bin/Python with an uppercase P. Opening the folder and checking, I found that the file or symlink was actually python with a lowercase p. Changing it from .../Python to .../python in the Pycharm settings fixed this problem. (I had to restart Pycharm afterwards.)
</blockquote>
It helped me too, but only when I switched to pipenv instead of the usual venv. I changed Python to python and the debugger worked, but I'm still getting errors/warnings:
<pre><code>OSError: [Errno 9] Bad file descriptor 
</code></pre>
But it works anyway. Without the debugger, it works as expected and without the error above.

<a href="https://i.stack.imgur.com/VRjgx.png" rel="nofollow noreferrer">My Answer</a>
Hi, i've been solve the problem, i followed this <a href="https://blog.ukena.de/posts/2021/encoding-error-when-debugging-a-pipenv-project-using-pycharm-on-osx/" rel="nofollow noreferrer">blog</a> but in my case it has been python (with lower case), so i try to change
from : {your project path}/venv/bin/python 
to : {your project path}/venv/bin/python3.8
i don't know why, but it's works for me.

Current conclusion:
The <code>encoding</code> of the <code>converted</code> file is <code>utf-8</code>-&gt;<code>utf-8 big</code>-&gt;<code>ansi</code> -&gt; <code>utf-8</code>. Reopen the file after each conversion.
After observing for a period of time, there is no such error.
<hr />
When I use PyCharm to debug <code>.py</code> files, the <code>same</code> file sometimes has UnicodeDecodeError, sometimes it’s normal. My operating system is Windows 10, PyCharm version is 2020.3.3 Community edition.
The error is as follows:
<pre><code>Traceback (most recent call last):
 File &quot;D:\Program Files\JetBrains\PyCharm Community Edition 2020.3.3\plugins\python-ce\helpers\pydev\_pydevd_bundle\pydevd_comm.py&quot;, line 301, in _on_run
 r = r.decode('utf-8')
UnicodeDecodeError: 'utf-8' codec can't decode bytes in position 1022-1023: unexpected end of data
</code></pre>
I tried to add the following code to the header of the file, but sometimes I still get an error, how to solve it?
<pre><code>#!/usr/bin/env Python
# coding=utf-8
</code></pre>
I found another way to save as a UTF-8 document with Notepad. I tried it, but there are still errors sometimes.
