Same problem on Amazon Linux 2018.03

Packages were updated today (from /var/log/yum.log):
Sep 07 02:00:09 Updated: python27-botocore-1.10.82-1.67.amzn1.noarch
Sep 07 02:00:11 Updated: aws-cli-1.15.83-1.49.amzn1.noarch

$ aws --version

File "/usr/lib/python2.7/dist-packages/awscli/clidriver.py", line 19, in
from botocore.hooks import AliasedEventEmitter
ImportError: cannot import name AliasedEventEmitter

It was fixed by downgrading aws-cli and python27-botocore:
python27-botocore-1.8.13-1.66.amzn1.noarch.rpm
aws-cli-1.14.9-1.48.amzn1.noarch.rpm

After downgrade:
$ aws --version
aws-cli/1.14.9 Python/2.7.14 Linux/4.9.85-37.55.amzn1.x86_64 botocore/1.10.49

[niklongstone]

same problem here, fixed with a downgrade:
$ aws --version
aws-cli/1.14.70 Python/2.7.14 Linux/4.14.51-60.38.amzn1.x86_64 botocore/1.10.60

Apparently it seems to caused that the implementation of botocore has changed

[masahitojp]

https://github.com/aws/aws-cli/commits/develop/awscli/clidriver.py

Well, I already seem to be getting well with this latest version 🤔

[chadawagner]

We had a similar problem after doing a yum update of aws-cli and python27-botocore. It turned out we also had a pip-installed botocore that was older than the version required by the new aws-cli. Removing (or else updating) the pip version resolved the issue. This might not be the same issue as @talonx reports but perhaps may help others who commented or are reading this thread.

[jphegley]

Same problem here an running a yum update on the Amazon AMI. Also fixed by downgrading aws-cli.noarch and python27-botocore:

sudo yum downgrade aws-cli.noarch python27-botocore

[jamesls]

@talonx It looks like for some reason the versions installed aren't actually being used.

Your output shows pip installing version 1.11.7 of botocore, which had the AliasedEventEmitter: https://github.com/boto/botocore/blob/1.11.7/botocore/hooks.py#L346, so this should work. My guess would be that the botocore that's being imported in the CLI isn't actually v1.11.7.

You could try this to see if the versions match up:

$ python -c "import botocore; print('%s: %s' % (botocore.__file__, botocore.__version__))"

We've also made a few changes since v1.16.7. Are you still seeing this issue on the latest version?

[jamesls]

@jdkindy It looks like the same issue in my previous comment, for whatever reason, even though you've installed 1.10.82, that's not the version that's actually being used in the CLI. v1.10.82 of botocore also has the AliasedEventEmitter as shown here so that should work without issue: https://github.com/boto/botocore/blob/1.10.82/botocore/hooks.py#L346

I also confirmed that if I install the CLI in a new virtualenv I'm not seeing any issues with either version affected here:

[texdc]

@jamesls test a fresh instance with the Amazon Linux AMI 2018.03.0.20180811 x86_64 HVM AMI and running yum update -y.

[johnbartels]

@jamesls
you stated:
"Your output shows pip installing version 1.11.7 of botocore, which had the AliasedEventEmitter: https://github.com/boto/botocore/blob/1.11.7/botocore/hooks.py#L346, so this should work. My guess... "

but, this commit(changing name of class 'AliasedEventEmitter' to 'EventAliaser'):
boto/botocore@f8b98a0#diff-155031df2de133bd9d662433e654c09a
was a child of this commit:
boto/botocore@384523c
which was in the 1.11.7 release (unless I am reading things incorrectly)

It seems (as previously mentioned by @masahitojp) that the root cause appears to be coming from botocore.

[netmanuy]

The update of the botocore installed with pip works to me to solve this issue:

pip install botocore==1.10.82

[gitbisect]

Running pip install awscli==1.15.83 fixed it for me. The way to validate was to run aws --version before and after the pip install.

[smet-dk]

It seems to me that actually this is all that is needed:
pip install awscli
Takes care of botocore too

#3542 (comment)

So this works, but you have to remove aws-cli via yum first completely. Then when installing the awscli via pip the exact command should be: pip install awscli --ugprade --user After that you have to update the path of the account you're in, and it works.

The only issue then you run into is that the upgrade/update only affects the account in question where its run first. So if you need it to be done globally, you need to look into modifying /etc/profile or profile.d or the ~/.bashrc files of each accounts on the instance in question.

That said, doing all of the above still leads to breakages if you have shell scripts that are leveraged by specific apps like tomcat:

sudo service tomcat restart
/opt/tomcat/bin/setenv.sh: line 4: aws: command not found
/opt/tomcat/bin/setenv.sh: line 5: aws: command not found
/opt/tomcat/bin/setenv.sh: line 6: aws: command not found
/opt/tomcat/bin/setenv.sh: line 7: aws: command not found
/opt/tomcat/bin/setenv.sh: line 8: aws: command not found
/opt/tomcat/bin/setenv.sh: line 12: aws: command not found
/opt/tomcat/bin/setenv.sh: line 13: aws: command not found
Using CATALINA_BASE: /opt/tomcat

and sudo is involved. I have not yet found a way to address this yet.

[Edit]

Easiest path forward would be to grab the latest CLI release and use the explicit boto version stated by looking at the commit ID and installing that (plus uninstalling any previous versions you might get with any other boto packages you might have grabbed in the process). That worked for me.

[always-hii]

pip install awscli --upgrade worked for me.

I saw a post saying boto requires higher version of awscli so that the error occurs. Upgrade the awscli first and then try it!

[1001b]

pip install awscli==1.15.83 fixed it for me...

[tauqirghani]

smet-dk solution worked for me
sudo pip install awscli

[CloudSatish]

smet-dk solution worked for me
sudo pip install awscli

Yes, this worked for me too.

[amyjiwu]

I had similar issue. It looks like aws cli copy command is working on emr-5.17.0 but not emr-5.20.0. Downgrade the aws-cli.noarch and python27-botocore by running: "$ sudo yum downgrade aws-cli.noarch python27-botocore" did fix the problem.
But after some more testing, I found out emr-5.17.0 or emr-5.20.0 is not the problem. aws cli copy command works on both EMR versions. The problem is in my bootstrap script. I ran "$ sudo pip install boto3", this installation uninstalled botocore-1.10.82 and installed boto3-1.9.109 botocore-1.12.109.
That's why running "$ sudo pip install awscli" also fix the problem. Because it uninstalled botocore-1.12.105 and installed botocore-1.10.82 for you.

[maxfarago]

Similar problem using MRJob to copy JARs via awscli to AWS EMR 5.19 image version:

+ aws s3 cp s3://mrjob-f239f1a076bbaf65/tmp/assign_tastes.maxfarago.20190308.143848.386468/files/commons-csv-1.1.jar commons-csv-1.1.jar

Fixed by adding the following to runner:

  emr:

[hienntt93]

I fix it by change the format of two file: ~/.aws/config and ~/.aws/credentials

[rashid199]

what change you performed on ~/.aws/config and ~/.aws/credentials

[desaijay315]

This worked for me -

sudo pip-2.7 install awscli --upgrade
