我需要一些新的Ubuntu 15.04 VM的帮助。我试图安装pip模块telnetlib3但是我遇到了一些错误：
pip install telnetlib3
Downloading/unpacking telnetlib3
Downloading telnetlib3-0.2.3.tar.gz (96kB): 96kB downloaded
Running setup.py (path:/tmp/pip-build-YojtJ4/telnetlib3/setup.py) egg_info for package telnetlib3

Complete output from command python setup.py egg_info:

----------------------------------------
Cleaning up...
Command python setup.py egg_info failed with error code 1 in /tmp/pip-build-YojtJ4/telnetlib3
Storing debug log for failure in /home/max/.pip/pip.log
我已经用谷歌搜索了它，但我找不到对我有用的东西。
非常感谢你的帮助！
