When upgrading to version 1.48.4 of Matillion ETL, users may experience problems with the AWS CLI no longer functioning correctly via the Bash component and the console. A symptom of this is the following error for any AWS CLI command:

[root@ip-xxxxxxxx ~]# aws s3 ls
Traceback (most recent call last):
File "/bin/aws", line 19, in 
import awscli.clidriver
File "/usr/lib/python2.7/site-packages/awscli/", line 36, in 
from import ProviderHelpCommand
File "/usr/lib/python2.7/site-packages/awscli/", line 23, in 
from import docevents
ImportError: cannot import name docevents

This error occurs because the version of the Boto3 library is incompatible with the AWS CLI version of the machine, giving the following incompatability:

1.18.75 of the aws cli is not compatible with Boto3 1.15.9


To resolve this issue, we recommend that users update the following packages to compatible versions, as outlined below:

pip install --upgrade awscli==1.18.150

This command will update the AWS CLI to version 1.18.150

And then:

pip install --upgrade boto3==1.15.9

This will upgrade boto3 to version 1.15.9

Users can confirm that each package has been updated by running these commands:

pip show awscli

Which will return:

Name: awscli
Version: 1.18.150


pip show boto3

Which will return

Name: boto3
Version: 1.15.9
