根因分析

PEP 668 阻止 pip 将包安装到系统 Python 环境中，以避免与操作系统包管理器冲突。这通常发生在 Debian/Ubuntu 等发行版上。

English

无效尝试

常见但无效的做法:

  1. 90% 失败

    Root privileges do not bypass the externally-managed-environment check; the error persists.

  2. 80% 失败

    Reinstalling pip does not change the environment management policy.

  3. 95% 失败

    This environment variable is unrelated to PEP 668 enforcement.
