Unclear how to remove Node.js version

[ai]

volta help uninstall does not show an example of how to remove a specific Node.js version.

All obvious ways do not help:

➜ volta list node
⚡️ Node runtimes in your toolchain:

    v10.22.1
    v12.19.0
    v14.14.0 (default)
    v15.0.0

➜ volta list uninstall [email protected]
error: Found argument '[email protected]' which wasn't expected, or isn't valid in this context

USAGE:
    volta list [FLAGS] [OPTIONS] [tool]

For more information try --help

➜ volta list uninstall node 10.22.1
error: Found argument 'node' which wasn't expected, or isn't valid in this context

USAGE:
    volta list [FLAGS] [OPTIONS] [tool]

Hi @ai, thanks for asking! We don't currently have a method to prune out the cached versions of tools, though we have an existing issue tracking that #330. Can you expand a bit on your use-case? Are you primarily looking to clean up the disk space used by different versions? Or is there another motivating factor in wanting to remove older versions?

Yeap, the main use case is just for keeping my desktop system clean

Okay, in that case I think tracking #330 or #327 which is related but not quite the same would be your best bet. Short-term, you can safely delete any of the (version-numbered) directories within ~/.volta/tools/image/node/ (%LOCALAPPDATA%\Volta\tools\image\node\ on Windows) to remove that version of Node from your system. If Volta comes across a package that uses that version in the future, it will be re-installed, so there shouldn't be any danger in deleting them.
