Python2.7.6用Pip9.0.3安装包遇InsecurePlatformWarning等警告求助

Hey there, let's work through this issue together. Those warnings aren't just noise—they're telling us your old Python 2.7.6 setup lacks critical SSL features modern package servers rely on. Here's how to get pyOpenSSL installed properly:

Step 1: Install SSL/SNI Support Packages #

First, we need to add missing components that enable SNI (Subject Name Indication) and secure HTTPS requests in Python 2.7.6. Run this command in your terminal:

pip install pyopenssl ndg-httpsclient pyasn1

These packages patch the older SSL module in Python 2.7.6 to support SNI, which will eliminate the SNIMissingWarning and address the InsecurePlatformWarning at the same time.

Step 2: Upgrade Pip to a Compatible Version #

Your current Pip 9.0.3 is also outdated and might struggle with modern PyPI server requirements. Since Python 2.7 is no longer supported, we need to upgrade to the last Pip version that works with it:

pip install pip==20.3.4

This updated Pip will handle SSL connections more reliably and avoid issues with package validation.

Step 3: Install PyOpenSSL Again #

Now that your setup has the necessary SSL support and an updated Pip, try installing pyOpenSSL once more:

pip install pyOpenSSL

This should complete without those warnings and successfully install the package.

Quick Note for the Future #

While these steps fix your immediate issue, keep in mind that Python 2.7 reached its end-of-life years ago. It's no longer receiving security updates, so you'll run into more compatibility problems over time. If possible, consider migrating your project to a supported Python 3.x version to avoid these headaches long-term.
