Configuring pip in Anaconda (D:\ drive) results in https; instead of https: on Windows 10

[Caswellwei]

Description

When configuring the pip mirror source in my Anaconda environment (installed on the D:\ drive), I noticed that the URL in the pip.ini file is misinterpreted, displaying https; (with a semicolon) instead of https: (with a colon). This causes pip commands to fail.

Expected behavior

Pip should correctly interpret https:// (colon) instead of https;// (semicolon), allowing me to install Python packages using the specified mirror.

pip version

Pip Version: 23.3.1

Python version

Python Version: 3.12.4

OS

Windows 10 64-bit

How to Reproduce

Steps to Reproduce
My Anaconda is installed in D:\Anaconda1.
I added the following content toD:\Anaconda1\pip\pip.ini:

[global]
index-url = https;//pypi.douban.com/simple
Ran the following command in the Anaconda prompt:

pip install numpy
Encountered the following warning and error:

WARNING: The index url "https;//pypi.douban.com/simple" seems invalid, please provide a scheme.

Analysis
I confirmed that my pip.ini file contains the following content:

[global]
index-url = https;//pypi.douban.com/simple
However, when I run pip commands, the https:// is incorrectly interpreted as https;//.
The issue seems to persist regardless of the corrections I make to the pip.ini file.

Output

Attempts to Resolve
I have already tried the following steps, but the issue persists:

Updated the URL in the pip.ini file to the following format:

[global]
index-url = https://pypi.douban.com/simple
Verified the location of pip.ini and ensured it is in the correct directory (D:\Anaconda1\pip).
Verified that pip is pointing to the correct Python environment in D:\Anaconda1.

[global]
index-url = https;//pypi.douban.com/simple

I'm confused. This is an invalid URL. Pip is reading it and trying to use it, but as it's invalid, pip gives an error explaining the problem.

If you fix your config, the problem should go away.
