升级 macOS 的 Vim

本文最近更新于 2018 年 01 月 13 日 ，大连

macOS 默认已经安装了 Vim，可执行程序是 /usr/bin/vim，当前的系统 Vim 版本有一个问题是不支持与系统剪贴板的集成，另外由于是系统集成版本，使用一段时间后往往会出现版本低于当前 Vim 最新版的情况。

✗ /usr/bin/vim --version | grep clipboard
-clipboard       +job             +path_extra      +user_commands
+eval            -mouse_dec       +statusline      -xterm_clipboard

解决方法是使用 Homebrew 安装 Vim 并替换系统自带 Vim：

brew install vim --with-override-system-vi

安装完成后重启终端以更新环境变量，输入 vim 后会发现 Vim 的版本已经是最新版本了。

如果以后想更新 Vim 版本，直接输入 brew upgrade vim 便能快速升级了。

如果想添加 python3 的支持，在以上命令基础上加上 --with-python3 即可，更多说明可以参见 brew info vim 命令结果：

✗ brew info vim                             
vim: stable 8.0.1400 (bottled), HEAD
Vi 'workalike' with many additional features

注意其中的 Required: perl ✔, ruby ✔，如果显示为 Required: perl ✔, ruby ✘：

✗ brew info vim                             
vim: stable 8.0.1400 (bottled), HEAD

则运行 vim 会报错：

✗ vim
dyld: Library not loaded: /usr/local/opt/ruby/lib/libruby.2.5.dylib
  Referenced from: /usr/local/bin/vim
  Reason: image not found
[1]    53425 abort      vim
✗

这时可以通过 Homebrew 安装 ruby 修复：

brew install ruby
