“from lunar_python import Lunar”这条语句报错

Traceback (most recent call last):
File "", line 1, in
File "/Applications/PyCharm CE.app/Contents/plugins/python-ce/helpers/pydev/_pydev_bundle/pydev_import_hook.py", line 21, in do_import
module = self._system_import(name, *args, **kwargs)
ImportError: No module named lunar_python
请问怎么解决啊，环境是python2.7

pip install lunar_python执行没？
