Question

例如，当我运行'gem install bundler'时，如果我运行ruby版本1.9.3，它运行正常，但是当运行ruby 2.1.2时，似乎没有看到'bundler'arg并且给了我

ERROR:  While executing gem ... (Gem::CommandLineError)
  Please specify at least one gem name (e.g. gem build GEMNAME)

我在运行rbenv的两个不同系统上看到了这一点。

以RBENV_DEBUG = 1：

运行时，这是输出的最后一部分

+ [rbenv-exec:45] export PATH=/home/ded/.rbenv/versions/2.1.2/bin:/home/ded/.rbenv  /libexec:/home/ded/.rbenv/plugins/bundler/bin:/home/ded/.rbenv/plugins/ruby-build/bin:.bundle/bin:/home/ded/.rbenv/shims:/home/ded/.rbenv/bin:/home/ded/.cabal/bin:/home/ded/.emacs/ded/lisp/ecukes:/home/ded/local/node/bin:/home/ded/j64-701/bin:/home/ded/bin:/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/local/plan9/bin

+ [rbenv-exec:47] exec -a gem /home/ded/.rbenv/versions/2.1.2/bin/gem install bundler
  ERROR:  While executing gem ... (Gem::CommandLineError)
    Please specify at least one gem name (e.g. gem build GEMNAME)

任何可能出错的建议？

Answer 1

从

更改了〜/ .gemrc

gem: --document

到

gem:  --ri-document

这解决了这个问题。不确定为什么它不是ruby 1.9.3的问题。

2.安装ruby

** $ sudo gem install ruby **

然后安装cocoapods然后完美工作 $ sudo gem install cocoapods
