Managing conda environments
It is recommended to install Zipline in an isolated conda environment. Installing Zipline in conda environments will not interfere your default Python deployment or site-packages, which will prevent any possible conflict with your global libraries. For more information on conda environment, see the Conda User Guide.

Assuming conda has been set up, you can create a conda environment:

$ conda create -n env_zipline python=3.10
Now you have set up an isolated environment called env_zipline, a sandbox-like structure to install Zipline. Then you should activate the conda environment by using the command

$ conda activate env_zipline
You can install Zipline by running
