Warnings on CLI with Python 3.8.1

[yanniskatsaros]

Description

When invoking the eb CLI for the first time after download (I installed using brew), a slew of Python warnings are printed to the console. However, after the first use these warnings do not show up again. Not a big problem, but just wanted to make this known.

Steps to reproduce

Invoke the eb CLI for the first time after installation: eb --version

Observed result

eb --version

Hi @yanniskatsaros, good callout. We will investigate these errors and post any updates in this ticket.

Thanks for reporting

[ondrek]

Same here. Mac OS X 10.15.4

> python --version 
Python 2.7.16

> eb --version
EB CLI 3.17.1 (Python 3.8.2)

[craigharman]

Same issue here and same versions of python/ebcli

[halcarleton]

Thanks for adding your own experiences to this issue. This issue is currently lower priority than some other bug fixes that are in the works, but we are continuing to track it and do plan on working on a fix in the future.

One thing to note about this issue is that some of the syntax warnings that occur are originating from dependencies of the EBCLI, meaning they will need to be resolved in those dependencies before we can incorporate the fixes into the EBCLI.

[JonLevy]

Experiencing the same issues here.

[HebeHH]

I'm also getting these.

[viniciosbarros]

I am also and still getting it. so annoying. but I was able to fix with: pip uninstall jmespath && pip3 install jmespath

[jbelmont]

I am also and still getting it. so annoying. but I was able to fix with: pip uninstall jmespath && pip3 install jmespath

Thanks that fixed for me!

[nguyenduyta]

same above, pip3 install jmespath fixed for me

I get similar warnings on macOS 12.5

$ eb --version

  if instance_types is "":
EB CLI 3.20.3 (Python 3.10.)

I am working around this by setting PYTHONWARNINGS="ignore" in the environment e.g.

$ PYTHONWARNINGS="ignore" eb --version
EB CLI 3.20.3 (Python 3.10.)

# set it for your shell lifetime. put this in shell rc file to make it permanent
export PYTHONWARNINGS="ignore"

[NihalM99]

$ eb --version EB CLI 3.20.7 (Python 3.11.4 (main, Jun 6 2023, 22:16:46) [GCC 11.3.0])

Unable to see warnings anymore , is anyone still facing the issue ?

[NihalM99]

Please reopen if you are still facing the issue .

Just installed through brew on mac osx and had this issue @NihalM99

[ billy@mac : dev ] eb --version

Weirdly the CLI is using python 3.11.5, but I have a later one installed:

[ billy@mac : dev ] python --version
Python 3.9.6

[ka1amita]

still the same after brew install aws-elasticbeanstalk got
