Hi All,
I have some problems running lean cli
In a completely new windows, installing anaconda with python 3.8, and running docker, I have the follow error:
(lean) PS C:\Users\juan> lean
Traceback (most recent call last):

The version of lean installed is 1.0.117
Also I tried with Python 3.9
Thanks for your help

Hi Juan,
Does the lean init command work?

Hi Derek,
The result is the same with the “lean init” command:
All my friends in the quant wolrd have the same error or similar
Thanks for all,
Derek Melchin
Hi Juan,
We were unable to reproduce the error. Please provide the steps you followed to install lean in the virtual environment. The path above (\Anaconda3\envs\lean\lib\site-packages\lean\) doesn't look like ours.
You could also try not installing lean in a virtual environment to see if that fixes the issue.
Best,
Derek Melchin
