Installation is broken: Requirement.parse('urllib3<1.23,>=1.21.1')

I'm running pip install --upgrade awscli awsebcli && rm -rf ~/.cache/pip \ && aws --version && eb --version

awscli returns this stacktrace:

Help!

Same issue on aws forum: https://forums.aws.amazon.com/thread.jspa?threadID=289084

Found workaround: pip install --upgrade "urllib3==1.22" awscli

This is actually unrelated to the awscli, and will happen if you install awsebcli by itself. The problem here is that awsebcli has requests and botocore as dependencies which both depend on urllib3, but have different upper bounds in the version that they allow so you end up running into this pip issue.

[kirillgroshkov]

But, but... as a sole user of awscli I'm not even a python person, do I need to know about underlying technologies if I just need CLI to work according to documentation?

In other words, is it possible to provide some kind of "binary" or prebuilt version of the CLI to avoid such problems in future?

[joguSD]

@kirillgroshkov You're absolutely right that as an end user of the CLI you shouldn't need to care that much about the fact that it's implemented in python. While we don't have a 'binary' exactly we do generate bundled installers which installs the AWS CLI and its dependencies in an isolated virtual environment to avoid dependency conflicts like these.

I'm not sure if the team that works on awsebcli has something similar or if pip is the only way to install it. Just to clarify, in your snippet above what failed above wasn't aws --version but eb --version.

@kirillgroshkov sorry you are facing this problem. It will be fixed in EBCLI 3.14.5 which will be out hopefully early next week.

This still appears to be an issue when installing from the other repository. I just ran a fresh install.

@sinjihn-4th-valley I just solved it with pip3 uninstall awsebcli && pip3 install --upgrade awsebcli 🤷
