I ran into this same issue on Windows 10. Here's how I fixed it:

<ol>
<li>Open your 'Environment Variables' (Under 'System Properties').</li>
<li>In the window that opens, select the 'Path' row, then click the 'Edit...' button.</li>
<li>There should be two environment variables <code>C:\Python37-32\Scripts\</code> and <code>C:\Python37-32\</code> Then click 'OK' (Make sure to check that these path values correspond to the location and version of your Python install.)</li>
<li>Next, in the top portion of the 'Environment Variables' window, look for the <code>PYTHONHOME</code> variable and make sure that it is also set to <code>C:\Python37-32</code></li>
</ol>

blocks|key|105752|text|这个问题已经在这个线程的here中得到了解决。显然，以管理员身份运行Python安装程序和/或正确设置环境变量解决了这个问题。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|105753|entityMap|0|LINK|mutability|MUTABLE|url|https://bugs.python.org/issue27054^0|C|4|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

This issue has been addressed <a href="https://bugs.python.org/issue27054" rel="nofollow noreferrer">here</a> in this thread. Apparently, running the Python setup as an administrator and/or correctly setting the environment variables solved this issue.

blocks|key|105755|text|首先，不要忘记在单击Install+now之前选择"Add+Python3.x+to+PATH“，并在安装后重新启动，这样Windows就会考虑到新的路径。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|105756|其次，我在Windows7和64位系统上的Python版本3也遇到了同样的问题，我从Windows+7系统环境变量中删除了PYTHONPATH和PYTHONHOME，因为我之前安装了Python版本2，这些路径指向我的Python版本2目录。我只需删除PYTHONPATH和PYTHONHOME变量。|105757|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

First, don't forget to select &quot;Add Python 3.x to PATH&quot; before you click on Install now and reboot after installation so that the new path is taken into account by Windows.
Second, I had the the same problem with Python 3 on Windows 7 and 64-bit and I got rid of it by deleting PYTHONPATH and PYTHONHOME from Windows 7 system environment variables, because I had a previous installation of Python 2 and those paths were pointing to my the Python 2 directory. I had to simply to delete the PYTHONPATH and PYTHONHOME variables.

blocks|key|2646507|text|我也遇到了同样的问题(我使用的是Mac，但我不认为这对这个问题有什么影响)，它来自于spyder中选定的Python解释器路径和当前工作目录之间的差异。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2646508|我使用Python中的虚拟环境来避免不同项目之间已安装模块的版本冲突(我认为这是一个很好的实践)。这导致我在spyder中通过访问以下内容来配置解释器路径：|2646509|preferences+>+python+interpreter+>+use+the+following+interpreter|code-block|syntax|javascript|2646510|当我从不同的路径启动spyder时，问题就来了。我得到了与Milo完全相同的错误。为了解决它，我看到了两个选择：|2646511|Python+|2646512|更改解释器路径以匹配spyder+working+directory|unordered-list-item|2646513|

I had the same problem (I use a Mac, but I don't think it makes any difference in this problem) and it was coming from the difference between the selected Python interpreter path and the current working directory in spyder.
I use virtual environments in Python to avoid version conflicts of installed modules between various projects (I believe it is a good practice). This leads me to configure the interpreter path in spyder by accessing:
<pre><code>preferences &gt; python interpreter &gt; use the following interpreter
</code></pre>
The problem comes when I launch spyder from a different path. I get exactly the same error as Milo's. To solve it I see two options:
<ol>
<li>change the interpreter path to match the spyder working directory</li>
<li>change the spyder working directory to match the Python interpreter path</li>
</ol>

blocks|key|108008|text|我通过删除我的虚拟环境并创建一个新的虚拟环境解决了这个问题。我相信在我的例子中出现这个错误是因为旧的虚拟环境是在Python+3.6上运行的，我最近卸载了它，并用Python+3.8替换了它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|108009|一般来说，这可能是不好的做法，但我没有任何真正的项目，版本是重要的。|108010|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

I solved this issue by deleting my virtual environment and creating a new one. I believe in my case the error came because the old virtual environment was running on Python 3.6, which I had recently uninstalled and replaced with Python 3.8.
This is probably bad practice in general, but I don't have any real projects where the version matters.

Even I had the same issue when I installed the Python 3.7 beta version, and I resolved it by following these steps:
<ol>
<li>If you have nay previous version of Python installed and the environment variable and path is set for that version already, just remove the path and environment variable
</li>
<li>Run the downloaded Python 3.7 EXE file file as administrator
</li>
<li>At the end of installation if it asks the permission for path length just click on that. Now type &quot;python&quot; on the command line and see. It should work.
</li>
</ol>

I am not sure why this question is still here without a solution. I just encountered this and solved by this:
<ol>
<li>Close all CMD or console emulators.
</li>
<li>Go to the system environment settings and clear all old Python path or environment settings. Make sure you check the PATH in both User and System settings as well.
</li>
<li>Try again <code>python -V</code> and see if you can run it or not.
</li>
</ol>
<ul>
<li>If you have removed all Python environment settings, I recommend you to reinstall Python and turn on the <code>Add Python to PATH</code> setting during installation.</li>
</ul>
