Last Updated Post

I delete folder urllib3 from path and execute command below to reinstall again .

but i get error as

C:\Users\sa\AppData\Roaming\Python\Python310\site-packages\pip\_vendor>pip install -U urllib3
Traceback (most recent call last):
  File "C:\Program Files\Python310\lib\runpy.py", line 196, in _run_module_as_main

    from pip._vendor.urllib3.exceptions import DependencyWarning
ModuleNotFoundError: No module named 'pip._vendor.urllib3'

this is collections init.py file

so what i modify or on which place i will modify

Answer 1

From Python 3.3 to 3.9, import Mapping from collections raised a DeprecationWarning:

DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3, and in 3.10 it will stop working

Since Python 3.10, it doesn't work anymore. It looks like you are using an old version of urllib3 because the selector.py file exists only on versions 1.20, 1.21 and 1.22. The current version is 1.26.

Upgrade urllib3 should solve the problem:

[...]# pip install -U urllib3

Update

Maybe you can remove manually the urllib3-X.Y.Z.dist-info and urllib3 folders in C:\Users\sa\AppData\Roaming\Python\Python310\site-packages\pip\_vendor\. After that reinstall urllib3.

Answer 2

Try editing the file

(C:\Program Files\Python310\lib\collections_init_.py )

and add to the import

from collections.abc import Mapping

Just add to collections (.abc) To get collections.abc
