ModuleNotFoundError: No Module named 'dateutil'

Hello,

I am pretty new with python. I am using python3 which I thought boto3 was compatible with. I am getting this error…

Traceback (most recent call last):
  File "application.py", line 2, in <module>
    import boto3
  File "/Users/noahbragg/Library/Python/3.6/lib/python/site-packages/boto3/__init__.py", line 16, in <module>
    from boto3.session import Session
  File "/Users/noahbragg/Library/Python/3.6/lib/python/site-packages/boto3/session.py", line 17, in <module>
    import botocore.session
  File "/Users/noahbragg/Library/Python/3.6/lib/python/site-packages/botocore/session.py", line 26, in <module>
    import botocore.credentials
  File "/Users/noahbragg/Library/Python/3.6/lib/python/site-packages/botocore/credentials.py", line 22, in <module>
    from dateutil.parser import parse
ModuleNotFoundError: No module named 'dateutil'

When I try to run the python application.

I am using pip3 and pip3 freeze shows that I do have boto3 installed…

boto3==1.4.7
botocore==1.7.31
certifi==2017.7.27.1
chardet==3.0.4
click==6.7
docutils==0.14
Flask==0.12.2
Flask-Session==0.3.1
idna==2.6
itsdangerous==0.24
Jinja2==2.9.6
jmespath==0.9.3
MarkupSafe==1.0
python-dateutil==2.6.1
requests==2.18.4
s3transfer==0.1.11
six==1.11.0
stripe==1.62.1
urllib3==1.22
Werkzeug==0.12.2

I import boto3 into my python file like normal. I’m wondering if this is an issue because I am using python3 or because i am using the latest of boto3. Any help would be appreciated! Thanks!

I found this was happening because, while I had installed awscli, I had not install boto3. So if you are writing tools that use the AWS libraries then you need boto3 and not just awscli.

So that looks like the path to a system level python, not brew python. The traceback seems to match the system python path. The python your pip3 is pointing at could be a different python, but it doesn’t seem likely.

You say you’re new to python. Are you familiar with virtualenv? If not there’s a short guide here. That should help you out with isolating environments.
