我在Ubuntu 16.04系统上用Python 2.7尝试执行sudo pip install pyperclip安装pyperclip包时，碰到了如下报错，而且安装其他部分包时也出现了一模一样的问题：

sudo pip install pyperclip
Traceback (most recent call last):
  File "/usr/bin/pip", line 9, in <module>
    from pip import main
  File "/home/ot/.local/lib/python2.7/site-packages/pip/__init__.py", line 26, in <module>
    from pip.utils import get_installed_distributions, get_prog
  File "/home/ot/.local/lib/python2.7/site-packages/pip/utils/__init__.py", line 22, in <module>
    from pip.compat import console_to_str, expanduser, stdlib_pkgs
ImportError: No module named compat

最后我通过执行以下两行命令成功解决了这个问题：

sudo apt-get update
sudo apt-get install python-pyperclip
