The biggest piece that is missing is you have to go out of your way to get sane dependency management. I have only used JS and F# (same dependency management as C#) out of your mentions, and it's the official tools that enable the local dependency management with a single command ("npm install X" or "dotnet add package X"). If you're using python, you don't know to check out pyenv/etc until you have a huge mess on your computer due to pip's behavior.
