Error detected while processing ~/.vim/pack/plugins/start/clrzr/autoload/clrzr.vim:-CodePudding

I am trying to install a fork of the colorizer plugin. It has minimal requirements, awk being one. But I seem to run in a bunch of errors.

line   31:

The plugin can be accessed here: https://github.com/BourgeoisBear/clrzr

Additionally, I am attaching the raw file that errors out: https://raw.githubusercontent.com/BourgeoisBear/clrzr/master/autoload/clrzr.vim

CodePudding user response：

:help :const was introduced in patch 8.1.1539. If your Vim doesn't recognize it, then it means that it is too old for that plugin.

You can either…

use the original version of the plugin, which doesn't seem to be using too many new features,
or make your own backward-compatible fork of that fork,
or upgrade Vim to a more recent version.

I would go with the third option.

Additionally, you might want to ask the author of that fork to clearly state the plugin's requirements.
