我这样写保存方案的时候，emacs给我弹出了一个错误
(color-theme-initialize)
(color-theme-vim-colors)
Warning (color-theme): This package is obsolete.
Since version 22.1 Emacs has built-in support for themes. That
implementation does not derive from the implementation provided
by this package. Back when this was new we referred to the new
implementation as `deftheme' themes, as opposed to `color-theme'
themes.
This package comes with a large collection of themes. If you
still use it because you want to use one of those, then you can
never-the-less migrate to the "new" theme implementation. The
`color-theme-modern' package ports all themes that are bundles
with `color-theme' to the `deftheme' format. It also ports a
few third-party themes. Its documentation contains setup
instructions. Don't forget to uninstall `color-theme'.
我应该怎么解决
