Old way
老办法
To remove a Ruby version from rbenv, delete the corresponding directory in ~/.rbenv/versions. E.g.
要从 rbenv 中删除 Ruby 版本，请删除~/.rbenv/versions. 例如
rm -rf ~/.rbenv/versions/1.9.3-p0
Run rbenv rehashafterwards to clean up any stale shimmed binaries from the removed version.
rbenv rehash之后运行以清除已删除版本中任何陈旧的填充二进制文件。

ruby-build now adds an uninstall commandto rbenv to handle the removal of ruby versions, if you want to avoid manual rm -fr(which might be considered risky) and rbenv rehashsuggested by @Stephenson. For removing ruby version 1.9.3-p0 you would run the following:
ruby-build 现在向 rbenv添加了一个卸载命令来处理 ruby 版本的删除，如果你想避免手动rm -fr（这可能被认为是有风险的）和rbenv rehash@Stephenson 的建议。要删除 ruby 版本 1.9.3-p0，您将运行以下命令：
rbenv uninstall 1.9.3-p0

Like Stephenson said, but remember to change version & global if they are referencing the deleted version.
就像斯蒂芬森说的那样，但如果他们引用已删除的版本，请记住更改版本和全局。
