「neocomplete requires Vim 7.3.885 or later with Lua support」 の解決

More than 1 year has passed since last update.

Arch Linux をアップデートしたら、Vimの補完プラグイン neocomplete が下記のエラーで動かなくなった。

下記のIssueを見たところ、 lua/dyn は単体では動作しないっぽい?

試しに :lua print "hello" としたところ

Could not load library liblua.so.5.3.4

というエラーが出たため、 sudo pacman -S lua で解決した。

ウィンドウマネージャーに Awesome を使っているため、古いほうが入っていたのかもしれない。
