Windows 10系统下能否升级Python3.6.3至3.6.5？pip升级失败怎么办？

1. Can Python 3.6.3 be upgraded to 3.6.5 on Windows 10? #

Absolutely! Python 3.6.3 and 3.6.5 are both part of the Python 3.6.x minor release series—these updates focus on bug fixes, security patches, and small tweaks that don’t break existing code. Windows 10 fully supports this upgrade, and you won’t run into compatibility issues with most projects built for Python 3.6.

2. Why didn’t pip work for upgrading, and what’s the correct method? #

Let’s clear up a common misconception: pip is built to manage Python packages (like requests or numpy), not the core Python interpreter itself. It can’t upgrade your base Python installation—so that’s why your pip command didn’t work.

To successfully upgrade from 3.6.3 to 3.6.5, you’ll need to use the official installer:

• Download the Python 3.6.5 installer for Windows, run it, and look for the "Upgrade Now" option. This will automatically replace your existing 3.6.3 setup while keeping your installed packages intact.
• Don’t forget to check the box labeled "Add Python 3.6 to PATH" during installation—this avoids annoying path-related errors later on.

Quick pro tip: Before upgrading, run pip freeze > requirements.txt in your command prompt. This saves a list of all your installed packages, so you can easily reinstall them if anything goes awry.
