python - 最新的 'pip' 失败，出现 "requires setuptools >= 0.8 for dist-info"

Question

使用最新 (1.5) 版本的 pip，我在尝试更新多个软件包时遇到错误。例如，sudo pip install -U pytz 会导致失败:

Wheel installs require setuptools >= 0.8 for dist-info support.
pip's wheel support requires setuptools >= 0.8 for dist-info support.

我不明白这条消息 (I have setuptools 2.1)或如何处理。

此错误日志中的异常信息:

Answer 1

这对我有用:

sudo pip install setuptools --no-use-wheel --upgrade

注意它是 sudo

的用法

更新

在 Windows 上，您只需以管理员身份执行 pip install setuptools --no-use-wheel --upgrade。在 Unix/Linux 中，sudo 命令用于提升权限。

更新 2

这似乎已在 1.5.1 中修复。
