Total Beginner - How to install Crew AI

Hi I am new to crew AI and coding in general. The instruction on the course module says:

If you’re running this notebook on your own machine, you can install the following:

!pip install crewai==0.28.8 crewai_tools==0.1.6 langchain_community==0.0.29

I tried running the above code on Jupyter notebook online on the Jupyter website but it gives me below error.

Can somebody please help me? Also, do you have any reference video or a doc that shows how can I download an IDE and run Python code on it and implement the Crew AI exercises?

Another question is, even in the course, despite on the left side of window a Jupyter notebook exists, I am unable to run any commands on it? For example in the first exercise, I have to replace the variable ‘Topic’ with ‘Artificial Inteliigence’ but it does not work. Can you please help?
