我的 Python 库刚刚更改了它的主模块名称foo.bar to foobar。为了向后兼容，foo.bar仍然存在，但导入它会引发一些警告。现在，似乎一些示例程序仍然从旧模块导入，但不是直接导入。
我想找出错误的地方import陈述。有没有什么工具可以让我跟踪导入并找到罪魁祸首，而无需费力浏览所有代码？
启动 python 解释器-v:
$ python -v -m /usr/lib/python2.6/timeit.py
# installing zipimport hook
import zipimport # builtin
# installed zipimport hook
# /usr/lib/python2.6/site.pyc matches /usr/lib/python2.6/site.py
import site # precompiled from /usr/lib/python2.6/site.pyc
# /usr/lib/python2.6/os.pyc matches /usr/lib/python2.6/os.py
import os # precompiled from /usr/lib/python2.6/os.pyc
import errno # builtin
import posix # builtin
# /usr/lib/python2.6/posixpath.pyc matches /usr/lib/python2.6/posixpath.py
import posixpath # precompiled from /usr/lib/python2.6/posixpath.pyc
# /usr/lib/python2.6/stat.pyc matches /usr/lib/python2.6/stat.py
import stat # precompiled from /usr/lib/python2.6/stat.pyc
# /usr/lib/python2.6/genericpath.pyc matches /usr/lib/python2.6/genericpath.py
import genericpath # precompiled from /usr/lib/python2.6/genericpath.pyc
# /usr/lib/python2.6/warnings.pyc matches /usr/lib/python2.6/warnings.py
import warnings # precompiled from /usr/lib/python2.6/warnings.pyc
# /usr/lib/python2.6/linecache.pyc matches /usr/lib/python2.6/linecache.py
import linecache # precompiled from /usr/lib/python2.6/linecache.pyc
# /usr/lib/python2.6/types.pyc matches /usr/lib/python2.6/types.py
import types # precompiled from /usr/lib/python2.6/types.pyc
# /usr/lib/python2.6/UserDict.pyc matches /usr/lib/python2.6/UserDict.py
...
然后只需 grep 查找您的旧模块即可。
