Python 3.x 导入错误：没有名为'；mstamp#u stomp'；

我正在尝试从git存储库运行demo.py。 这是本文的源代码。我已经附上下面的代码

导入错误：没有名为“mstamp\u stomp”的模块

这反映了一个搜索路径问题。您需要将chdir插入包含源代码的目录，并且在执行代码之前，还需要在路径中有

点：

$ cd mstamp/Python
$ export PYTHONPATH=.
$ python demo.py

您可以使用此代码片段调试以下问题：

import pprint
import sys
pprint.pprint(sys.path)

您可能需要考虑具有多维支持的Staby开源Python库：
