Why am I getting an old version of rector?

Question

I ran composer require rector/rector --dev, then vendor/rector/rector/bin/rector init. This is the output:

Rector v0.5.23
                                  
  Command "init" is not defined.  
                                  

I know this is an old version of Rector, but I have no idea how to get an up-to-date version

Hi, probably other packages in your project. Composer can only install packages that are compatible with them.

Try: https://github.com/rectorphp/rector-prefixed

What PHP version do you use?

[jkester1986]

was using PHP 7.1. Switched over to 7.2, I think I'm ok now? I don't see anything in the readme mentioning what version to use, but the init command did work now.

Good 👍

Each tag uses different version, you can see it in composer.json. E.g. last one uses PHP 7.3 as min:

rector/composer.json

Line 23 in e00106e

"php": "^7.3|^8.0",
