This is what I'm using on msys2 to install python3:

<pre><code>$ pacman -Syuu
</code></pre>

Close and restart msys2.

<pre><code>$ pacman -S mingw-w64-x86_64-python3-bsddb3 mingw-w64-x86_64-gexiv2 mingw-w64-x86_64-ghostscript mingw-w64-x86_64-python3-cairo mingw-w64-x86_64-python3-gobject mingw-w64-x86_64-python3-icu mingw-w64-x86_64-iso-codes mingw-w64-x86_64-hunspell mingw-w64-x86_64-hunspell-en mingw-w64-x86_64-enchant
</code></pre>

To deal with this error "No intltool or version &lt; 0.25.0, build_intl is aborting" perform the following:

<pre><code>$ pacman -S intltool
</code></pre>

Add these to test:

<pre><code>$ pacman -S mingw-w64-x86_64-python3-lxml
$ pacman -S mingw-w64-x86_64-python3-jsonschema
</code></pre>

Execute this command to verify python3 is properly installed:

<pre><code>$ python3 --version
Python 3.6.4
</code></pre>

It can be confusing why there are two versions of Python, but both serve different use cases:

<ol>
<li>MINGW - Windows native applications</li>
<li>MSYS2 - POSIX applications emulated to work in Windows</li>
</ol>

MINGW refers to executables that are compiled using the MINGW GCC Compiler and target the Win32 API. MSYS2 refers to executables that are compiled by MSYS2 GCC Compiler and make use of a POSIX emulation layer.

I understand as a user this can be confusing, why do you care which compiler and API Python is compiled against? Well some programs you may want to make use of, are dependent on running in a POSIX environment. It would be very hard and time consuming to port these applications to Windows. In these cases, MSYS2 provides an emulation layer to allow these applications to work. Unfortunately, making use of this emulation layer is very very slow.

So in general, if you can use the MINGW version of Python, you should because it will be much faster. But if you are trying to run a Python application that depends on being in a POSIX environment, then MSYS2 provides an emulation layer to help make it work.

For more information, the <a href="https://github.com/git-for-windows/git/wiki/The-difference-between-MINGW-and-MSYS2" rel="nofollow noreferrer">Git for Windows Wiki</a> provides a more detailed explanation.

blocks|key|568172|text|这可能有点晚了，但我在MSYS2中使用了原生。我这样做是为了确保Python添加了环境变量。之后，我创建了一个新的Windows环境变量PYTHONPATH=C:\Users\Glen.Nicholls\AppData\Local\Programs\Python\Python37\Lib\site-packages。我还将MSYS设置为在MINGW64.ini中继承。现在，我将pip和python的别名添加到我的.bashrc中：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|568173|alias+python='$PYTHONPATH/../../python.exe'
alias+pip='$PYTHONPATH/../../Scripts/pip.exe'|code-block|syntax|javascript|568174|这不是最干净的解决方案，但它在我的环境中工作得很好。此外，请记住，如果您运行which+python，它将不会指向正确的安装。|568175|另一种不创建别名和以上所有内容的方法是将路径更改为在msys路径之前包含继承的Windows路径。您可以手动编辑它，也可以在.bash_profile或.bashrc中添加一些花哨的内容。|568176|entityMap^0|1W|2I|4Q|B|5A|3|5E|6|0|0|12|C|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@$9|R|A|S|B|C]|$9|T|A|U|B|C]|$9|V|A|W|B|C]|$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|10|8|@$9|11|A|12|B|C]]|D|@]|E|$]]|$1|M|3|N|5|6|7|13|8|@]|D|@]|E|$]]|$1|O|3|-4|5|6|7|14|8|@]|D|@]|E|$]]]|P|$]]

This is probably kind of late, but I use the native Windows install of python in MSYS2. The way I did this was to ensure that Python added the environment variable. After this, I created a new Windows environment variable <code>PYTHONPATH=C:\Users\Glen.Nicholls\AppData\Local\Programs\Python\Python37\Lib\site-packages</code>. I also set MSYS to inherit in the <code>MINGW64.ini</code>. Now, I add the alias for <code>pip</code> and <code>python</code> to my .bashrc:
<pre><code>alias python='$PYTHONPATH/../../python.exe'
alias pip='$PYTHONPATH/../../Scripts/pip.exe'
</code></pre>
This isn't the cleanest solution, but it works in my environment just fine. Also, keep in mind that if you run <code>which python</code> it will not point to the correct install.
Another method without creating aliases and all the above would be to change your PATH to include the inherited Windows PATH before the msys PATH. You can either edit this manually or put something fancy in your .bash_profile or .bashrc.

While the current official Python version is 3.6, msys2 provides two packages for <code>python3</code>:

<ul>
<li><code>msys/python3</code>, <a href="https://github.com/git-for-windows/MSYS2-packages/blob/7d77534a4f03a28ff36649db124e51cf4eb4414a/python3/PKGBUILD#L7" rel="nofollow noreferrer">currently using 3.4</a></li>
<li><code>mingw64/mingw-w64-x86_64-python3</code>, <a href="https://github.com/git-for-windows/MINGW-packages/blob/9f5f700254f3038c47a79c83986fb1edc4f7abcc/mingw-w64-python3/PKGBUILD#L19" rel="nofollow noreferrer">currently using 3.5</a></li>
</ul>

So which version should I use when and how? Can't I just use the Windows 3.6 and somehow tell <code>pacman</code> to use that? Or can I get 3.6 running in a msys/mingw'd version and also use that in Windows so I don't need two/three installations?

Which Python should I install (and how) when using msys2?
