Importing imp in standard_library raises a PendingDeprecationWarning

[jfinkels]

The imp package is pending deprecation in favor of importlib as of Python 3.4.

$ python3.5 -Wonce -c "import future.standard_library"
[...]/lib/python3.5/site.py:165: DeprecationWarning: 'U' mode is deprecated
  f = open(fullname, "rU")
[...]/lib/python3.5/site-packages/future/standard_library/__init__.py:66: PendingDeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses
  import imp

The recommended alternative is described here.

Any hope to get this fixed? Still happening after 3 years.

Assuming no one has plans to fix this? Currently tracking the source of a DeprecationWarning and found this along the way.

Editing in an idea here, but what's the potential cost of importing imp in conditions requiring Python2 only, with a workaround for situations requiring it in Python3? Python 3.12 will drop all support for imp. Given there are several libraries in the wild that actively depend on python-future for the sole purpose of maintaining Py2 support, I'd like to find a fix in as efficient a manner as possible.

I'd work out a solution myself, but I'm not working with python-future directly, but rather as a dependency of python-whois. Working out a solution on my own risks breaking something, as I'm not using python-future directly. Thanks.

Greetings again from the future. We're now in the days of Python 3.11, with Python 3.12's release looming ever closer. There is an open PR (#574) from 2019 to close this issue.

Is python-future dead? Once Python 3.12 releases, this project will be left in a forever broken state if not updated.
Please merge the pending PR.

EDIT 2: Updating my previous edit, it would seem the imp module deprecation is still present in 0.18.3. Will this ever be fixed?

The imp module has now been removed from Python 3.12.

• Remove more deprecated importlib APIs from Python 3.12 python/cpython#98040
• gh-98040: Remove just the imp module python/cpython#98573

Python 3.12 will be in beta in two weeks, and set for release on 2023-10-02 and this library is one of the top 5,000 most-downloaded from PyPI.

Please could you upgrade to use importlib? The imp docs have suggestions on what to use to replace each function and constant.

For people googling, in python 3.12, importing future.standard_library raises “ModuleNotFoundError: No module named 'imp'”:

ImportError: Failed to import test module: myfile
Traceback (most recent call last):
  …
  File "myfile.py", line 41, in <module>
    from future import standard_library
  File "/opt/hostedtoolcache/Python/3.12.0/x64/lib/python3.12/site-packages/future/standard_library/__init__.py", line 65, in <module>
    import imp
ModuleNotFoundError: No module named 'imp'

In my case, I resolved the error by replacing those imports that need future.standard_library.install_aliases() with six instead (see imports2):

• urllib.parse --> six.moves.urllib.parse
• urllib.error --> six.moves.urllib.error
• urllib.parse -->six.moves.urllib.parse
• dbm.ndbm --> six.moves. dbm_ndbm
• http.server --> six.BaseHTTPServer, six.CGIHTTPServer, or six.SimpleHTTPServer
• tkinter.filedialog --> six.tkinter_tkfiledialog
• tkinter.simpledialog --> six.tkinter_simpledialog
• xmlrpc.server --> six.xmlrpc_server
