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，指出此模块丢失。当我尝试sudo pip install ordereddict这似乎将它安装到我的 Python 3.6 版本时......我不认为sudo pip3 install ordereddict应该安装到 3.6。

因此，我从 PYPI 页面尝试以下操作：

sudo python2.7 -m pip install ordereddict

不幸的是，虽然这在执行时会引发以下错误：

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

谁能告诉我我做错了什么？

谢谢

在python2.7OrderedDict中是内置的结构。

from collections import OrderedDict

python 3.6 dicts 中的 PS 已经订购，所以你不需要它。
