![]() 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. python setup.py install to install your altered copy of version.py. Shift Right-Click → Open command window here - instructions on enabling this feature in Windows 10). ![]() from itertools import izip, count for t in izip (count (start 1, step 1. Open a command window in the same folder as version.py ( ex. Python 3 does not need this any more as the built-in zip is already an iterator. Without using itertools, you could use a function to iterate through the values of the current key, append each value to the combination and call itself with the updated combination and the next index. 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. It goes through each element of each passed iterable, then returns a single iterator with the contents of all passed iterators. chain() The chain() function takes several iterators as arguments. The project you are attempting to install is listed there as version. Itertools is a Python module of functions that return generators, which are objects that only function when iterated over. 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\ except ImportError: Python 2from itertools import iziplongest as ziplongest. 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. ImportError: cannot import name 'izip_longest' In Python 3, izip() and imap() have been removed from itertools and replaced the zip() and map() built-ins. So I tried pip install version which gave me the error below: from itertools import izip_longest To return an iterator, the izip() and imap() functions of itertools must be used. ModuleNotFoundError: No module named 'version' ![]() I am trying to fix an error: import version ![]()
