I installed AWSCLI by using:

pip install --upgrade --user awscli

Now if I type aws configure in the cmd I get: 'aws' is not recognized as an internal or external command...

I'm pretty sure the path needs to be set correctly. I know how to go into the environment variables to set the path, but I don't know WHAT to set the path to because I don't see where awscli is installed. By the way, I already have boto3 installed and I'm able to import that just fine.

I should also mention I'm setting this up in windows.

Hi I just had the same problem, and I managed to solve this!

I'm using python 3.7.0 and pip version 18.

I installed awscli using

pip install --upgrade --user awscli

but it is not added in PATH, and I have no idea how to find it.But when I decided to delete it, running

pip uninstall awscli

it told me that

Uninstalling awscli-1.15.65:
Would remove:c:\users\riz\appdata\roaming\python\python37\scripts\awsc:\users\riz\appdata\roaming\python\python37\scripts\aws.cmdc:\users\riz\appdata\roaming\python\python37\scripts\aws_bash_completerc:\users\riz\appdata\roaming\python\python37\scripts\aws_completerc:\users\riz\appdata\roaming\python\python37\scripts\aws_zsh_completer.shc:\users\riz\appdata\roaming\python\python37\site-packages\awscli-1.15.65.dist-info\*c:\users\riz\appdata\roaming\python\python37\site-packages\awscli\*

So I know the file was installed in

c:\users\riz\appdata\roaming\python\python37\scripts\aws

you just need to add this to PATH! Good Luck!
