最新的“ pip”失败，并显示“需要dist-info的setuptools> = 0.8”

Question

使用的最新（1.5）版本pip，尝试更新多个软件包时出现错误。例如，sudo pip install -U pytz由于以下原因导致失败：

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

日志中有关此错误的异常信息：

Exception information:

    status = self.run(options, args)

    finder = self._build_package_finder(options, index_urls, session)

    raise InstallationError("pip's wheel support requires setuptools >= 0.8 for dist-info support.")
InstallationError: pip's wheel support requires setuptools >= 0.8 for dist-info support.

Answer 1

这为我工作：

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

注意它是sudo的用法

更新

在窗口上，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。

更新

这似乎已在1.5.1中修复。
