Neovim崩溃之后：安装RubyGem时的help命令

Question

问题原因

问题是由一些名为LustyExplorer的插件引起的。通常，当我在Vim中遇到一些错误时，我总是首先删除所有插件和自定义。但在转到Neovim之后，我忘了先做这件事。

原始问题

我最近刚使用以下命令在OsX El Capitan v10.11.6上安装了nvim 0.2.2：brew install neovim

$ brew info neovim

Run :checkhealth for more info

nvim正常运行。但是在安装neovim RubyGem之后，我无法在:help中使用neovim命令。应用程序立即崩溃：

$ gem install neovim
Fetching: neovim-0.6.2.gem (100%)
Successfully installed neovim-0.6.2
1 gem installed

在:help中执行nvim命令会出现以下错误消息：

nvim(69661,0x7fff7274e000) malloc: *** error for object 0x7f9414310d00: pointer being freed was not allocated
   *** set a breakpoint in malloc_error_break to debug
                                                  [1]    69661 abort      nvim

我使用rvm 1.26.11来管理ruby。

$ rvm list

rvm rubies

=* ruby-2.1.1 [ x86_64 ]

$ rvm --version
