vfox install nodejs fails on Windows when using msys2 bash

[jcrben]

I installed vfox via scoop: scoop install vfox. A prior issue on the vfox main repo discusses more about my vfox environment, which uses msy2 bash: version-fox/vfox#172

As shown below, vfox install nodejs failed with this message:

Please use `vfox install nodejs@<version>` to install the version you need.
plugin [PreInstall] method error: C:\Users\ben\.version-fox\plugin\nodejs\hooks\pre_install.lua:23: cannot perform concat operation between string and nil

Maybe it was supposed to fail and you have to specify a version? I think some spacing and tweak to the wording could help then.

Thanks for feedback this that is a known issue, see version-fox/vfox#205.

We plan to fix this issue on vfox, not plugins.
