跟踪 Python 导入 [英] Trace Python imports

问题描述

我的 Python 库刚刚将它的主要模块名称从 foo.bar 更改为 foobar.对于向后兼容，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.

My Python library just changed it's main module name from foo.bar to foobar. For backward compat, foo.bar still exists, but importing it raises a few warnings. Now, it seems some example program still imports from the old module, but not directly.

我想找出错误的import 语句.是否有任何工具可以让我在不涉足所有代码的情况下跟踪导入并找到罪魁祸首?

I'd like to find the erroneous import statement. Is there any tool that allows me to trace imports and find the culprit without wading through all of the code?

推荐答案

用-v启动python解释器:

Start the python interpreter with -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
...

然后只需为您的旧模块 grep 即可.

Then just grep for your old module.
