With that in mind, though not guaranteed, you may still run into issues down the road when actually using the module. It is also noted on the module page on PyPi that the module itself is (was) in an "Alpha" stage of development. You are likely aware of this, but the reason you are running into the issue with import izip_longest verus import zip_longest is because this module is intended for Python 2.x, not Python 3.x. For example, let’s suppose there are two lists and you want to multiply their elements. This module works as a fast, memory-efficient tool that is used either by themselves or in combination to form iterator algebra. python setup.py install to install your altered copy of version.py. Python’s Itertool is a module that provides various functions that work on iterators to produce complex iterators. Shift + Right-Click → Open command window here - instructions on enabling this feature in Windows 10). Open a command window in the same folder as version.py ( ex. Replace import izip_longest with import zip_longest, as noted in your original question, and then save version.py. Note that you will need to go through the process of decompressing the archive twice (once for the original version-0.1.1.tar.gz file, then once for the remaining version-0.1.1.tar file).įind version.py. To alter and then install version.py in Python 3.x:įully extract version-0.1.1.tar.gz (you can use 7-zip for this on Windows). In your case, this archive includes version.py. So rather than using pip, you can simply download the files yourself as a compressed tar.gz archive using the Download files link. The project you are attempting to install is listed there as version. How do I mitigate this issue and edit the file so that I can run pip install version successfully?Īs a rule, pip pulls modules from PyPI. C:\TruCalvin\testsfolder>pip install versionĬomplete output from command python setup.py egg_info:įile "C:\Users\Tru~1\AppData\Local\Temp\pip-install-d5jk1cru\version\setup.py", line 4, in įile "C:\Users\Tru~1\AppData\Local\Temp\pip-install-d5jk1cru\version\version.py", line 2, in Ĭommand "python setup.py egg_info" failed with error code 1 in C:\Users\Tru~1\AppData\Local\Temp\pip-install-d5jk1cru\version\ So going through different forums, I realized I need to update the file using this import argument import izip_longest and update it to import zip_longest.īut that file version.py seems to be a temporary file and I am unable to access it in Windows 10. You'll still have to import the itertools module to use it. islice () wasn't ported into the built-in namespace of Python 3. They all return iterators and don't require imports. ImportError: cannot import name 'izip_longest' Note: As of Python 3, filter (), map () and zip () are functionally equivalent to Python 2's itertools functions ifilter (), imap () and izip (). So I tried pip install version which gave me the error below: from itertools import izip_longest ModuleNotFoundError: No module named 'version' I am trying to fix an error: import version
