AttributeError: module 'certifi' has no attribute 'where'

Hello,

I found the following issue when using elasticsearch==5.0.0

It seems to be a problem when setting up the connection due to the module ‘certifi’ because it has no attribute ‘where’

Thanks for your help on beforehand.

Hi,

I encountered this as well.

For a minimal reproduction, run:

docker run -it jupyter/minimal-notebook /bin/bash
$ pip install elasticsearch
$ python -c "import elasticsearch"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/opt/conda/lib/python3.5/site-packages/elasticsearch/__init__.py", line 17, in <module>
    from .client import Elasticsearch
  File "/opt/conda/lib/python3.5/site-packages/elasticsearch/client/__init__.py", line 4, in <module>
    from ..transport import Transport
  File "/opt/conda/lib/python3.5/site-packages/elasticsearch/transport.py", line 4, in <module>
    from .connection import Urllib3HttpConnection
  File "/opt/conda/lib/python3.5/site-packages/elasticsearch/connection/__init__.py", line 3, in <module>
    from .http_urllib3 import Urllib3HttpConnection
  File "/opt/conda/lib/python3.5/site-packages/elasticsearch/connection/http_urllib3.py", line 10, in <module>
    CA_CERTS = certifi.where()
AttributeError: module 'certifi' has no attribute 'where'

What happen is that import certifi give a weird namespace, which has nothing:

>>> import certifi
>>> certifi
<module 'certifi' (namespace)>
>>> dir(certifi)
['__doc__', '__loader__', '__name__', '__package__', '__path__', '__spec__']

I think you should just add certifi to your install_requires (or improve the check using hasattr).

For now I can use the workaround of pip install -U certifi, but it’s annoying.

I just had the same problem here. Installing certifi (using pip) fixed the problem as mentioned above. I’m using both conda and pip. Maybe that’s the problem, because before reinstalling certifi it wasn’t being displayed in the pip freeze listing. Maybe the conda version is somehow broken. I’ll try and investigate it further later.
