- which version of Julia? (output of `versioninfo()`)
- what’s in the current environment? (output of `using Pkg; Pkg.status()`)

I ran into a problem which and I am not sure how to solve it. I added the ThinkJulia.jl package as suggested on the book and tried the command “using ThinkJulia” and it didn’t work. Then, I tried “build ThinkJulia” which failed because of ImageMagick. I tried “build ImageMagick” and end up on the same error. The problem seems to be acce…

So - it might not be a good idea to spend too much time trying to troubleshoot this issue.

The contents of the book are (mostly) still worth reading.

Was informed that ThinkJulia was an old package, and many users have encountered problems while trying to install it. Hence, I am skipping the topic, and continue to read up on Julia.
