当我尝试通过vmc工具管理我的mysql服务时.我收到如下错误:

when I try to manager my mysql service by vmc tool. I got a error like below:

我的ruby版本有麻烦吗?我只是使用ubuntu来源的apt安装它. 最后，我为我的英语不好道歉.

Is that some trouble with my ruby version?I just install it with apt from ubuntu source. At the end, I make apologies for my poor English.

推荐答案

我们建议您至少使用1.9.2或Ruby版本，最简单的安装方法是使用RVM-

we recommend you use at least version 1.9.2 or Ruby, the easiest way to install this is with RVM - https://rvm.io/rvm/install/, have a good scan over this site before continuing

要安装它，只需在终端窗口中运行以下命令；

To install it, just run the following command in a terminal window;

$ curl -L https://get.rvm.io | bash -s stable --ruby

RVM允许您管理多个版本的ruby，它还将在该版本中安装的所有宝石存储在用户的主目录中，这意味着您可以安装宝石而不必使用sudo！

RVM allows you to manage multiple versions of ruby, it also stores any gems installed for that version in your users home path which means you can install gems without having to use sudo!

一旦安装了RVM，我将继续安装Ruby的1.9.3版本；

Once RVM is installed, I would go ahead and install version 1.9.3 of Ruby;

$ rvm install 1.9.3

然后告诉RVM默认使用此版本

Then tell RVM to use this version by default

$ rvm use 1.9.3 --default

完成此操作后，您需要重新安装以前为1.8.7安装的所有gem，因此请重新安装vmc和caldecott

Once you have done this you need to re-install any gems you may have previously installed for 1.8.7, so re-install vmc and caldecott

$ gem install vmc
$ gem install caldecott
