最新的'pip'失败,"要求setuptools> = 0.8 for dist-info"

Question

使用最近的(1.5)版本pip,我在尝试更新多个包时遇到错误.例如,sudo pip install -U pytz导致失败的原因是:

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

我不明白这个消息(我有setuptools2.1)或者该怎么做.

此错误的日志中的异常信息:

Answer 1

这对我有用:

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

注意它是sudo的用法

UPDATE

在窗口中,您只需要以pip install setuptools --no-use-wheel --upgrade管理员身份执行.在unix/linux中,sudo命令用于提升权限.

UPDATE

这似乎已在1.5.1中修复.

Answer 2

首先,你永远不应该运行'sudo pip'.

如果可能,您应该使用系统包管理器,因为它使用GPG签名来确保您没有运行恶意代码.

否则,请尝试升级setuptools:

easy_install -U setuptools

或者,尝试:

pip install --user <somepackage>

这当然是"全球"包装.理想情况下,您应该使用virtualenvs.
