Hi @alex.nae01 ,

This issue occurs from time to time but it's out of our scope.
One way to bypass it is to install blocking dependency before retrying refinitiv-data install.

pip install numpy
...
pip install refinitiv-data

Note that when you want to install a new version, it's recommended to use following command line:

pip install --upgrade refinitiv-data

It'll update all dependencies at the expected version too

Hi, thank you so much for your response, I have spoken with refinitiv helpdesk and they diverted me to this forum. I really dont know who I can ask for help on this. I have tried installing numpy and then refinitiv-data only to get the same error.

I found same error here => pkgutil library only supports Python 3.11 and older !
Are you using Python 3.12 ?

yes, yes I am, I will roll to an older version and keep you updated. thank you for your help

Hello @alex.nae01

I suggest you try the Python Virtual environment tools like Anaconda or Miniconda Python distribution/package manager for manage your Python environments. With Conda, you can create multiple Python environments that use different Python and libraries versions.

### Example with Miniconda ###

Step 1: Create a new environment.

(base) C:/conda create --name RDLib python=3.10

Step 2: Activate the RDLib environment.

(base) C:/conda activate RDLib 
(RDLib) C:/pip install refinitiv.data

You can find more detail about the Python environment management from this Conda: Managing environments page.

There is a step-by-step guide about how to setup the Refinitiv Data Library - Python on PyCharm IDE using Conda available on https://developers.lseg.com/en/article-catalog/article/how-to-set-up-python-development-project-with-pycharm page.

I hope this information helps.
