【问题描述】：

抱歉可能重复。我正在使用 Rasbian Lite 操作系统。当我尝试安装包电子邮件时：

 pi@raspberrypi:~ $ sudo pip3 install email

我收到错误消息：

 Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple

但是，当我运行时：

 sudo pip install cStringIO

我收到一个错误：

 Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
 ERROR: Could not find a version that satisfies the requirement cStringIO (from versions: none)
 ERROR: No matching distribution found for cStringIO

所以我似乎因为无法安装 cStringIO 而被卡住了？任何想法/建议/解决方案将不胜感激。

谢谢！

【问题讨论】：

cstringio 是一个 Python 2 标准库，在 3 中不再存在。我猜您尝试安装的库在 2->3 转换之前被放弃了

标签： python python-3.x pip debian package-managers

【解决方案1】：

已解决：在终端中使用了错误的 python 版本
