Aws-cli: More SyntaxWarning issues with Python 3.8

[john-aws]

I'm seeing SyntaxWarning issues with the latest awscli and Python 3.8 versions.

john:~$ aws --version
aws-cli/1.16.310 Python/3.8.1 Darwin/18.7.0 botocore/1.13.46

Symptoms:

I am seeing the same thing on a new clean machine.
aws-cli/1.17.0 Python/3.8.1 Darwin/19.2.0 botocore/1.14.0

[wjam]

This issue in the jmespath library appears to be tracking the problems with that library that causes those messages

This should be fixed in 1.17.7 and 1.17.8. I tested both versions and could not see any more SyntaxWarning messages.

[dashmug]

I'm using

aws-cli/1.17.8 
Python/3.8.1 
Darwin/19.2.0 
botocore/1.14.8

and yet the warnings still show up.

Also, my aws-cli is installed via Homebrew (i.e. brew install awscli). Not sure if installing via pip is better.

[temal-]

On what commands do you see the warnings?

[robvanderleek]

I have these warnings too:

Had the same issue, upgraded outdated python modules and voila the SyntaxWarning message went away.

Here is the command to update:

pip3 list --outdated --format=freeze | grep -v '^\-e' | cut -d = -f 1  | xargs -n1 pip3 install -U

[robvanderleek]

I installed awscli via Homebrew but there's no update available yet that fixes these warnings.

[tayfunyasar]

i have same issue.

tayfun@tayfun-tayfun:~$ aws --version
aws-cli/1.17.8 Python/3.8.1 Linux/5.3.0-26-generic botocore/1.14.8

[hicklemon]

Uninstalling awscli from brew and installing it via pip3, which I do concede is not ideal since it's system-wide Python, cleaned up these warnings for me.

brew uninstall awscli
sudo pip3 install awscli

$ aws --version
aws-cli/1.17.9 Python/3.7.6 Darwin/19.2.0 botocore/1.14.9

[NobleUplift]

Well, it seems I went from one error to the next. Initially started with this error so I upgraded Python which forced an update of awscli, and here I am.

dyld: Library not loaded: @executable_path/../.Python
  Referenced from: /usr/local/Cellar/awscli/1.14.30/libexec/bin/python3.6

@saidsef 's command above worked for me! No more errors with brew awscli.

Thanks saidsef, works like a charm, annoying warning messages are gone!

[hicklemon]

Please be careful allowing pip to mass-upgrade modules -- you could conflict with python packages installed by your system's package manager, resulting in issues when performing a full system upgrade.

It is advised that you instead uninstall awscli, and pip install it.

[at0ms]

Built awscli formula locally with 1.17.9 artifact. Python syntax warnings stopped.

Workaround is cloning homebrew-core.git locally, tick the archive/package version in Formula/awscli.rb to .9 , then:

brew upgrade --build-from-source ./Formula/awscli.rb

Your brew managed awscli should now be at 1.17.9

[bugre]

Check if you don't have two version of awscli installed (brew and pip)

Had similar warnings and could not figure out why, as i had everything updated...
Found out it was related to having two install's of awscli. Long long time ago i had installed awscli with pip (awscli-1.16.130), and later moved to brew version (after updating today it's awscli: stable 2.0.0) but didn't unistall the old version.
Path pointed (as far i could find out) to the correct brew version, but for some reason the old installed 'pip3' version was generating havoc...

to check:
brew info awscli
pip3 list installed |grep awscli

after i removed the pip version, my brew installed awscli stopped complaining about 'if x is 0 or x is 1:' ...

pip3 uninstall awscli

[slmingol]

I was experiencing a similar issue, pip uninstall jmespath resolved the issue. I had jmespath installed via brew.

The same issue and resolved by pip install --upgrade jmespath

[weyderfs]

I was experiencing a similar issue, pip uninstall jmespath resolved the issue. I had jmespath installed via brew.

I made a little bit different, I my _jmespath_ was installed by PIP using python 2.7...
So I uninstall and re-install using pip3 and solved.

[aymenabdelwahed]

I've got the same issue which I resolved with:
pip uninstall jmespath; pip3 install jmespath

8 months later and the issue still exists with homebrew. I absolutely do not want to install pip and deal with python version issues directly on Mac OS. Homebrew has been the defacto package manager for Mac OS for well over a decade now.

[kdaily]

Hi @john-aws et al, the Homebrew formula for the AWS CLI is not managed by AWS, but by the Homebrew maintainers. I do not experience the SyntaxWarnings on Python 3.8 using one of the supported installation mechanisms. You would need to open an issue with the Homebrew team.

[oojacoboo]

@kdaily how about Amazon step up and deal with it.. work with them... or you know... maintain it... This PIP garbage is ridiculous.
