根因分析

包的元数据文件（如 PKG-INFO、setup.py）包含非 ASCII 字符，但没有正确的编码声明。pip 的元数据解析器在某些环境中默认使用 ASCII。

English

A package's metadata file (e.g., PKG-INFO, setup.py) contains non-ASCII characters without proper encoding declaration. pip's metadata parser defaults to ASCII in some environments.

解决方案

  1. 75% 成功率 
    Download the package source, edit the metadata file to add an encoding declaration (e.g., # -*- coding: utf-8 -*-), and install locally.
  2. 70% 成功率 
    Report the issue to the package maintainer; meanwhile, try installing an older version that may not have the problematic characters.

无效尝试

常见但无效的做法:

  1. 80% 失败

    Affects I/O encoding, not the encoding used when reading package files.

  2. 90% 失败

    The issue is in the package's metadata, not pip.
