最新的"pip"失败，并显示“需要dist-info的setuptools> = 0.8" [英] Latest 'pip' fails with "requires setuptools >= 0.8 for dist-info"

问题描述

使用pip的最新(1.5)版本，尝试更新多个软件包时出现错误.例如，sudo pip install -U pytz会导致失败，

Using the recent (1.5) version of pip, I get an error when attempting to update several packages. For example, sudo pip install -U pytz results in failure with:

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

我不理解此消息(我有setuptools 2.1)或如何处理.

I don't understand this message (I have setuptools 2.1) or what to do about it.

推荐答案

这对我有用:

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

请注意它是sudo的用法

Note it's usage of sudo

更新

在窗口上，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.

On window you just need to execute pip install setuptools --no-use-wheel --upgrade as an administrator. In unix/linux, sudo command is for elevating permissions.

更新

此问题似乎已在1.5.1中修复.

This appears to have been fixed in 1.5.1.
