Question

Centos 7

我已经安装了ruby 2.1.2和rubygems，但是当我运行rubygems --version时，我收到错误rubygems：command not found。

我的$ PATH是/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/lib/ruby/gems/2.1.0:/root/.gem/ruby/2.1.0

gem environment

安装的yum list显示了rubygems.noarch

我需要做些什么来让rubygems工作？

Answer 1

要在centOS上安装ruby和rubygems，请在终端上运行

sudo yum install ruby
sudo yum install rubygems

要检查ruby和rubygems的版本，请运行

ruby -v
gem -v

注意： gem --version与gem -v

相同

使用以下方式更新宝石列表：

sudo gem update
sudo gem update --system

现在，您可以使用命令

安装任何gem

gem install <gem_name>

例如，要在centOS上安装rails，请运行

sudo gem install rails

找不到Rubygems命令
