正常升级一直失败：python -m pip install --upgrade --no-cache-dir pip ，

更换为python -m pip install --user --upgrade pip 成功了。

使用 python -m pip install --user --upgrade pip 成功的原因主要有以下几点：

用户权限：--user 选项会将 pip 安装到用户目录，而不是全局系统目录。这样可以避免因为权限不足而导致的安装问题。
避免冲突：如果系统中有多个 Python 安装或 pip 版本，使用 --user 可以确保你正在更新用户环境中的 pip，而不是系统环境中的 pip，从而减少潜在的冲突。
环境隔离：将 pip 安装到用户目录可以避免与系统全局环境中的库发生冲突，特别是在一些权限受限的环境中。
简单安全：在没有管理员权限的情况下，使用 --user 选项是一个安全的选择，因为它不会影响其他用户的环境
