Tech Note 22nd September 2020


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
