https://ruby-china.org/lwd369 en-us <p>ruby 新人一枚。。最近碰到一个奇怪的问题</p> <p>在运行完 rails 生成器生成模型／控制器等文件后，再进入沙盒环境的 rails conosle 就会报 ruby 解释器错误：</p> <pre class="highlight shell"><code>rails g model User name:string rails console <span class="nt">--sandbox</span> <span class="c">#抛出错误</span> <span class="c">#上方行数太多了,terminal无法显示完全</span> <span class="nb">.</span> <span class="nb">.</span> <span class="nb">.</span> <span class="nb">.</span> 1558 /Users/x/.rvm/gems/ruby-2.3.1/gems/railties-5.0.0.1/lib/rails/commands/console_helper.rb 1559 /Users/x/.rvm/gems/ruby-2.3.1/gems/railties-5.0.0.1/lib/rails/commands/console.rb 1560 /Users/x/.rvm/gems/ruby-2.3.1/gems/railties-5.0.0.1/lib/rails/console/app.rb 1561 /Users/x/.rvm/gems/ruby-2.3.1/gems/railties-5.0.0.1/lib/rails/console/helpers.rb <span class="o">[</span>NOTE] You may have encountered a bug <span class="k">in </span>the Ruby interpreter or extension libraries.
