Using the recent (1.5) version of pip, I get an error when attempting to update several packages. For example, sudo pip install -U pytzresults in failure with:
使用最新的 (1.5) 版本时pip，我在尝试更新多个软件包时收到错误消息。例如，sudo pip install -U pytz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.
I don't understand this message (I have setuptools2.1)or what to do about it.
我不明白这条消息（我有setuptools2.1）或如何处理它。

This worked for me:
这对我有用：
sudo pip install setuptools --no-use-wheel --upgrade
Note it's usage of sudo
注意它是 sudo 的用法
UPDATE

On window you just need to execute pip install setuptools --no-use-wheel --upgradeas an administrator. In unix/linux, sudocommand is for elevating permissions.
在窗口上，您只需要以pip install setuptools --no-use-wheel --upgrade管理员身份执行即可。在 unix/linux 中，sudo命令用于提升权限。

This appears to have been fixed in 1.5.1.
这似乎已在 1.5.1 中修复。

First, you should never run 'sudo pip'.
首先，你永远不应该运行“sudo pip”。
If possible you should use your system package manager because it uses GPG signatures to ensure you're not running malicious code.
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。
Otherwise, try upgrading setuptools:
否则，请尝试升级 setuptools：
easy_install -U setuptools
Alternatively, try:
或者，尝试：
pip install --user <somepackage>
This is of course for "global" packages. You should ideally be using virtualenvs.
这当然适用于“全局”包。理想情况下，您应该使用 virtualenvs。
