"No Java runtime present, requesting install" for Ghidra Installation

Question

Trying to run Ghidra, which require me to download Java runtime and development kit (JDK) and put it on the path. I extracted the JDK and got the bin.

However, I'm not really sure how to do the following steps:

1. Open ~/.bashrc with an editor of your choice. For example: vi ~/.bashrc

Do I need to download vim for this? I tried inputting this in homebrew and got nothing but a INSERT at the bottom. And when I type step 2 in it it didn't work as well.

2. At the very end of the file, add the JDK bin directory to the PATH variable: export PATH=/bin:$PATH

I'm using a Macbook and it would be appreciated if someone can guide me through the process! Thanks :)

Answer 1

After a typical installation of Java/JDK it should already be on the path. You can verify this by opening the Terminal app and typing in java -version.

If you did a non-standard installation I suggest using homebrew to install the JDK. Then there should be no reason to update your ~/.bashrc file.

As regards to the editor - use whatever you like. If you know how to use vim, you can definitely try it - it should be preinstalled on macOS (just type vim in the Terminal).
