嗨，我想我在这里缺少一些基本的知识。
我正在使用Capistrano进行“集成”，然后进行“测试”。
我似乎无法添加gem，然后使用Capistrano成功地部署到其中一个网站（“测试”）。 但是，我可以将它成功部署到另一个（“集成”）。
我正在尝试添加bootstrap-sass'〜> 3.0.2.0'，但是当我尝试添加它们时，其他gem也会出现相同的错误。
当我尝试通过“上限测试部署”部署到“测试”时，出现错误消息

etc..
我花了很长时间寻找答案，但没有成功。 我有

end
end
我尝试通过编辑Gemfile和Gemfile.lock来直接在“测试”网站中安装gem，以使其与我的开发和“集成”站点中的内容保持一致，并运行捆绑安装。
然后当我“捆绑表演”时
bundle show bootstrap-sass
....../.rvm/gems/ruby-1.9.3-p448/gems/bootstrap-sass-3.0.2.1
接着：
bundle exec gem list
Could not find bootstrap-sass-3.0.2.1 in any of the sources
Run `bundle install` to install missing gems.
上限测试部署仍然失败
在可以正常工作的站点上，如下所示安装了gem：
bundle show bootstrap-sass
...../registration/shared/bundle/ruby/1.9.1/gems/bootstrap-sass-3.0.2.1
这与我在无法正常工作的网站上手动安装它的位置不同。
因此，我的问题是：
为什么Capistrano无法在一个站点上添加新的宝石而在另一个站点上成功？
我应该直接在无法正常运行的网站上安装gem吗？ 如果这是个好主意，我将如何将其安装到正确的位置？

现在让我的评论成为答案：
它现在正在运行-似乎不同的红宝石版本存在问题。 我在本机上有1.9.7 p448，测试有1.9.7 p484。 我们只是将每台计算机上的所有版本都设置为同一版本，现在我可以使用Capistrano根据对Gemfile的更改来更新gem。
