Development Environment On Mac

I am not a professional developer, I do it for fun. And I like to play around, discover new technologies,. development all kinds of little things. So sometimes I need Python, sometimes React/Typescript, Java and more. For every development tool or langugae there are multiple options on how to install them and manage their versions. Since I tend to forget things like “How did I install Python oin this machine?”, this is a note to future me, telling me how I installed every development tool.

As the way how certain packages are installed might change over time, I will add dates to my installation choices.

• Docker
• Java
• Maven
• Gradle
• Node and npm
• Python
• Ruby

Docker

January 2025: I switched away from Docker Desktop to Rancher Desktop.

Installation note: Downloaded the Apple Silicon version, opened the DMG and copied it into my Applications directory. The only detail I needed to do, is tick the “Administrative Access” checkbox in the setting.

Registry: I use different registries when working on different projects.

Question: How do I configure docker so that it pulls images from a specific registry?

Java

These are the option I saw:

• jenv
• SDK man

Januar 2025: I decided to use SDK Man as it also covers Maven.

Mini-Cheatsheet

• sdk install java 17.0.12-jbr install this specific Jaa version
• sdk list java shows all available Java version (available to install)
• To list the installed java versions:
  • sdk oofline enable, so it will list only locally installed versions
  • sdk list java
  • sdk offline disable
• sdk default java 21.0.6-amzn sets this version as default To set a java version as default inside a directory, see the Env command

Maven

I simply use brew install maven. For older version brew install maven30 installs Maven 3.0.

Gradle

January 2025: I decide to use SDK Man for Gradle as well.

Reason: brew install gradle installed Gradle Version 8.12.1, but for the current Project I needed 8.5.

• sdk install gradle 8.5: Installs teh specific gradle version
• sdk use gradle 8.5

Node and npm

January 2025 I decided to use nvm.

Mini-Cheatsheet

• nvm use 16
• node -v shows the version currently being used
• nvm install 12 installs node 12 and uses it

Python

• Summer 2024:I use pyenv
• To install pyenv: brew install pyenv

Mini-Cheatsheet

Select a Pyenv-installed Python as the version to use, run one of the following commands:

pyenv shell <version> -- select just for current shell session
pyenv local <version> -- automatically select whenever you are in the current directory (or its subdirectories)
pyenv global <version> -- select globally for your user account

Ruby
