Vim / command-T：忽略“gem-name”，因为它的扩展名没有构建。 试试gem原始“gem名”
每当我在MacVim中第一次打开command-T插件时，我会得到以下终端：
Ignoring atomic-1.1.13 because its extensions are not built. Try: gem pristine atomic-1.1.13 Ignoring atomic-1.1.10 because its extensions are not built.

听起来你跳过了命令-T的安装。 从文档
然后还必须编译C扩展; 例如，如果Vimball在〜/ .vim中安装你的插件文件，那么你会这样做：
cd ~/.vim/ruby/command-t ruby extconf.rb make
另请注意，必须针对相同版本的ruby编译命令T和vim。
我最近从rvm切换到chruby并运行gem update --system ，这就是问题开始发生的时候。 在那之后，无论何时我运行捆绑，我都会被同样的警告宰杀。
Ignoring curb-0.8.6 because its extensions are not built. Try: gem pristine curb-0.8.6
这个，以及其他gem的其他几十个警告。
不确定是什么修复它，但我做了2件事，警告消失了：
gem update bundler gem install curb
