blocks|key|826077|text|与@+when+1124一样，我在下载工具(又名pyqt5-+tools+)时也解决了同样的问题。经过多次尝试，我发现将python降级为3.9.x+(特别是3.9.9)版本很有帮助。如果您目前有python+3.10，它可能会有帮助，但否则，idk.|type|unstyled|depth|inlineStyleRanges|entityRanges|data|826078|我尝试过的其他方法没有解决这个问题，但也许也解决了其他问题，这些方法也与问题相关：|826079|从Microsoft版本的python到站点的章节。|unordered-list-item|826080|只使用pyqt5+(我最初使用的是5和6)。|826081|降级pip+(升级后立即)。|826082|我只知道这些，祝你好运:)|826083|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|P|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|Q|8|@]|9|@]|A|$]]|$1|G|3|H|5|F|7|R|8|@]|9|@]|A|$]]|$1|I|3|J|5|F|7|S|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|T|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|U|8|@]|9|@]|A|$]]]|N|$]]

Like @Ken1124 i tackeled the same issue when trying to download the tools (aka pyqt5-tools). After many tries I found it helpful to downgrade python to version 3.9.x (specifically to 3.9.9) from 3.10.x.
If you currently have python 3.10 it might help, but otherwise idk...
Other methods that I tried which I didn't see to fix the issue, but perhaps fixed other problem assosicated with the issue as well:
<ul>
<li>Changing from Microsoft Store version of python to the site's verstion.</li>
<li>using only pyqt5 (I first had both 5 &amp; 6).</li>
<li>Downgrading pip (right after upgrading).</li>
</ul>
That's all I know,
wish you good luck :)

blocks|key|839692|text|最近我也遇到了同样的问题。当您查看PyPi下载站点时，您可以在Installation章节中读到您需要“Qt的qmake工具在路径上”。在安装了Qt的开发文件之后，一切对我来说都很好。因此，首先安装它，并确保它在您的道路上，而不是再尝试。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|839693|sudo+apt-get+install+qtbase5-dev

I faced the same problem these days. When you have a look at <a href="https://pypi.org/project/PyQt5/" rel="nofollow noreferrer">PyPi download site</a>, you can read in the Installation chapter that you need &quot;Qt's qmake tool on PATH&quot;. After installing Qt's development files everything worked fine for me. So first install it and make sure it's on your PATH and than try again.
<pre><code>sudo apt-get install qtbase5-dev
pip install pyqt5
</code></pre>
PS: I think it has nothing to do with your python or pip version. I tried many versions and had this problem every time. It's just missing, corrupted or not found header development files from qt5.
Regards,
Vali

Below steps worked for me

<li>Uninstall python</li>

<li><code>python -m pip install PyQt5</code></li>

It should fix this error.

blocks|key|417004|text|我遇到了同样的问题，然后我重新安装python3.9，它是修复后。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|417005|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I met the same problem and then I reinstall the python3.9, it`s fixed after.

blocks|key|417007|text|好的，我在python中遇到了这个问题，在搜索之后，我找到了两个解决这个问题的方法，因为这个问题不仅存在于3.10.4中，还存在于其他库中。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|417008|#注:如果您有上述问题，这些解决方案可供下载任何库，而我在windows中遇到了这些问题。|417009|所以你可以试试这个方法：|417010|pip+install+turtle==0.0.1|code-block|syntax|javascript|417011|0.0.1+--这是库的最后一个版本，因此您应该找到要为此目的安装的库的版本，可以使用以下命令找到库的版本：|417012|pip+show+module+<name_of_the_library>|417013|另一个可行的解决方案是使用--use-deprecated=backtrack-on-build-failures。|417014|示例：|417015|pip+install+turtle+--use-deprecated=backtrack-on-build-failures|417016|希望能帮助你。|417017|entityMap^0|1H|6|0|0|0|0|0|5|0|0|D|18|0|0|0|0^^$0|@$1|2|3|4|5|6|7|12|8|@$9|13|A|14|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|15|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|16|8|@]|D|@]|E|$]]|$1|J|3|K|5|L|7|17|8|@]|D|@]|E|$M|N]]|$1|O|3|P|5|6|7|18|8|@$9|19|A|1A|B|C]]|D|@]|E|$]]|$1|Q|3|R|5|L|7|1B|8|@]|D|@]|E|$M|N]]|$1|S|3|T|5|6|7|1C|8|@$9|1D|A|1E|B|C]]|D|@]|E|$]]|$1|U|3|V|5|6|7|1F|8|@]|D|@]|E|$]]|$1|W|3|X|5|L|7|1G|8|@]|D|@]|E|$M|N]]|$1|Y|3|Z|5|6|7|1H|8|@]|D|@]|E|$]]|$1|10|3|-4|5|6|7|1I|8|@]|D|@]|E|$]]]|11|$]]

Ok, I faced this issue with python <code>3.10.4</code> and after searching I found two solutions for this problem because this problem not being only with turtle but for other libraries.
#Note: These solutions for downloading any library if you have a problem mentioned above and this faced me in windows.
So you could try this way:
<pre><code>pip install turtle==0.0.1
</code></pre>
<code>0.0.1</code> This is the last version of the library so you should find the version of the library that you want to install for this purpose, you can find the version of the library using this command:
<pre><code>pip show module &lt;name_of_the_library&gt;
</code></pre>
another solution that could work is using <code>--use-deprecated=backtrack-on-build-failures</code>
Example:
<pre><code>pip install turtle --use-deprecated=backtrack-on-build-failures
</code></pre>
Hope to help you.

An easier solution that worked for me on an M1 Mac.

<li>Execute your code using Python 3.7.

I still can install other packages like lxml but can't install pytq5. I'm installing everything in virtual environment.
Any ideas ??
