Rasbian Lite：电子邮件Python软件包安装（没有名为'cStringIO'的模块）

Question

对不起，可能重复。我正在使用Rasbian Lite操作系统。当我尝试安装软件包电子邮件时：

 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
 Collecting email

----------------------------------------
 ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.

但是，当我跑步时：

 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

所以似乎我被卡住了，因为我无法安装cStringIO？任何想法/建议/解决方案将不胜感激。

谢谢！
