Hi,  
I am new to the julia paradigm and have been trying to run the tutorials in the JuliaCon2021. I use their project.toml and instantiate my project. I get some errors with most .jll files which I am not sure how to fix. I then try to run IJulia and receive the following error. I am running julia 1.6.2 (the tutorial did say it was tested on julia 1.6.0)

Did you try to run `Pkg.resolve()` as suggested in the error log?

Hi Arrigo,  
Thank you for your suggestion.  
I tried `Pkg.resolve()` but received no changes:

julia\> Pkg.resolve()  
No Changes to `D:\DataScience\Julia\JuliaCon2021\JuliaCon2021-StatisticsWithJuliaFromTheGroundUp\Project.toml`  
No Changes to `D:\DataScience\Julia\JuliaCon2021\JuliaCon2021-StatisticsWithJuliaFromTheGroundUp\Manifest.toml`

When I try `Pkg.precompile()`, it throws following errors:

I have julia 1.5.4 as well as julia 1.6.2. Will that cause an issue?

Thank you

Having different Julia versions installed is not a problem. You just need to reinstall all the Julia packages that you need in each version (they don’t carry over). By the way, I don’t see any error messages in the last log.

I still can’t seem to get some of the libraries working. For instance `using IJulia` throws following error:

What does the MbedTLS\_jll does not have JLLWrappers in its dependencies mean? I tried precompile and resolve, nothing seems to work!

Thanks again
