Zipline installation issue

This is the error message I am getting. Zipline installation is a mystery!

Any help is appreciated.

Open your CMD.exe prompt for your environment and run this below:

conda update --all

Try importing zipline after in Jupyter and see if you get any errors.

Also check the python version in your environment. 3.8 was having this issue but it works in 3.9. You may have to upgrade python if you are running 3.8 in your zipline env
