无法将 ordereddict 安装到 Ubuntu 18 上的特定 Python 版本

Question

我正在尝试将 ordereddict 模块安装到我的 Python 2.7 设置中，因为当我尝试执行代码时收到一条错误消息，指出缺少此模块。当我尝试 sudo pip install ordereddict 时，这似乎将它安装到我的 Python 3.6 版本中......我的印象是 sudo pip3 install ordereddict 应该安装到 3.6.

因此，我正在尝试 PYPI 页面中的以下内容：

sudo python2.7 -m pip install ordereddict

不幸的是，执行时会抛出以下错误：

gdogg371@ubuntu:~$ sudo python2.7 -m pip install ordereddict

谁能告诉我做错了什么？

谢谢

在python2.7中OrderedDict是内置结构。

from collections import OrderedDict

P.S。在 python 3.6 中已经订购了字典，因此您不需要它。
