if you are still seeing an older ruby check your symlink
ls -la /usr/bin/rubyfrom hector
如果您仍然看到较旧的 ruby，请检查您的ls -la /usr/bin/rubyhector符号链接

Since this question was answered I have found a new alternative here:
自从回答了这个问题后，我在这里找到了一个新的选择：
https://www.brightbox.com/docs/ruby/ubuntu/
https://www.brightbox.com/docs/ruby/ubuntu/
In short:
简而言之：
# For ubuntu >= 14.04 install software-properties-common
# instead of python-software-properties
sudo apt-get install python-software-properties
sudo apt-add-repository ppa:brightbox/ruby-ng
sudo apt-get update
sudo apt-get -y install ruby2.2 ruby-switch
sudo ruby-switch --set ruby2.2
I must say that according to my tests this is faster than the alternatives shown here, because the compiling step is skipped.
我必须说，根据我的测试，这比此处显示的替代方案更快，因为跳过了编译步骤。

I particularly like ruby-install, available here: https://github.com/postmodern/ruby-install
我特别喜欢 ruby-install，可以在这里找到：https: //github.com/postmodern/ruby-install
It will install ruby (any version), JRuby, etc., and has many other features besides.
它将安装 ruby（任何版本）、JRuby 等，此外还有许多其他功能。

The better way to install ruby on ubuntu without RVM is to install it with rbenvin terminal as follows:
在没有 RVM 的情况下在 ubuntu 上安装 ruby 的更好方法是在终端中使用rbenv安装它，如下所示：
$ sudo apt-get update
Install the rbenv and Ruby dependencies with apt-get:
使用 apt-get 安装 rbenv 和 Ruby 依赖项：
$ sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev
Now run these commands as follows:
现在运行这些命令如下：
$ cd
$ git clone https://github.com/rbenv/rbenv.git ~/.rbenv
$ echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
$ echo 'eval "$(rbenv init -)"' >> ~/.bashrc
$ exec $SHELL
$ git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
$ echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
$ exec $SHELL
