此问题中的所有shell命令都将从foo目录的父目录中运行。
这是我的软件包目录foo的样子：
$ ls foo
__init__.py bar.py foo.py
以下是每个文件的内容：
$ cat foo/__init__.py
"""Pacakge foo."""
$ cat foo/foo.py
"""Foo module
Example:
>>> from foo import foo
>>> foo.main()
hello, world
"""
def main():
print('hello, world')
$ cat foo/bar.py
cat foo/bar.py
"""Foo module
Example:
>>> from foo import bar
>>> bar.main()
hello, world
"""
def main():
print('hello, world')
这是我面临的问题：
$ python3 -m doctest foo/bar.py
$ python3 -m doctest foo/foo.py

为什么foo/foo.py的doctest失败？
