Question

我在我的macbook上将Ruby正确升级到2.3.0时遇到了一些麻烦。我按照这里的说明操作：https://gorails.com/setup/osx/10.11-el-capitan

然而，我仍然无法安装厨师零（这是我必须升级的原因），以及我的Gem＆＃34; classpath＆＃34;似乎仍然指向旧的Ruby版本：

amencke@offplantever-lm ~/d/chef-repo> rbenv local
2.3.0
amencke@offplantever-lm ~/d/chef-repo> rbenv global
2.3.0
amencke@offplantever-lm ~/d/chef-repo> ruby -v
ruby 2.3.0p0 (2015-12-25 revision 53290) [x86_64-darwin14]

到目前为止似乎还不错......

amencke@offplantever-lm ~/d/chef-repo> gem environment

amencke@offplantever-lm ~/d/chef-repo>

如果我尝试安装chef-zero：

amencke@offplantever-lm ~/d/chef-repo> sudo gem install chef-zero 
Password:
ERROR:  Error installing chef-zero:
    chef-zero requires Ruby version >= 2.1.0.
amencke@offplantever-lm ~/d/chef-repo>

有什么想法吗？我对Ruby没有特别的经验（或者在OSX上创建开发环境） - 我们非常感谢正确方向的一点！

这里的答案是我正在使用鱼壳。来自linux backgroup我急忙更新环境设置是~/.bash_profile。这些设置已在此处解释：rbenv not changing ruby version。因为我还是不喜欢鱼，所以简单地使用chsh -s /bin/bash改回bash是没有问题的，并且嘿presto：

offplantever-lm:~ amencke$ gem env

干杯，亚瑟

无法成功升级Ruby - Gem仍然使用旧的ruby版本
