AWS CLI file extension association warning on Windows

file association not found for extension py windows 10
configure aws cli on windows
aws cli set profile
configure aws cli in linux
aws cli test credentials
aws cli without credentials
aws cli login with username and password
aws cli get access key

Using aws cli with pythno 3 on Windows, always getting a warning, but the program runs well after this message.

For example:

>>> aws --version --debug
Не найдено сопоставление для расширения имени файла .py.
aws-cli/1.15.83 Python/3.6.0 Windows/7 botocore/1.10.82

(vaguely -' Cannot find association for filename extension .py')

Any idea which part of aws scripts issues this warning and how to fix it? At what part does aws use Windows call?

If you reference a binary value in a file using the file:// prefix notation, the AWS CLI handles the file according to the current cli_binary_format setting. If that setting's value is base64 (the default when not explicitly set), the CLI expects the file to contain base64-encoded text.


I managed to get feedback on a issue on Github. Basically, there is a one line change that can supress the warning.

In aws.cmd instead of:

for /f "tokens=2 delims==" %%i in ('assoc .py') do (

use:

for /f "tokens=2 delims==" %%i in ('assoc .py 2^> nul') do ( 

This diverts warnings to null. There is also a pull request with this suggested change, but it was not mergerged to code unfortunately.

Anyone experiencing this problem can change a local file aws.cmd as <your python directory>/Scripts folder.
