安装ruby

sudo apt-get install ruby

sudo apt-get install ruby

~$ ruby -v
ruby 2.7.1p83 (2020-03-31 revision a0c7c23c9c) [x86_64-linux-gnu]

安装rails

sudo gem install rails
//这里我没有加sudu，报错ERROR:  While executing gem ... (Gem::FilePermissionError)
//You don't have write permissions for the /var/lib/gems/2.7.0 directory.

这里安装rails过程中报错：

ERROR:  Error installing rails:
	ERROR: Failed to build gem native extension.

    current directory: /var/lib/gems/2.7.0/gems/nokogiri-1.10.10/ext/nokogiri
/usr/bin/ruby2.7 -I /usr/lib/ruby/2.7.0 -r ./siteconf20201028-18843-bo1rnj.rb extconf.rb
mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h

You might have to install separate package for the ruby development
environment, ruby-dev or ruby-devel for example.

提示我们需要安装ruby-dev或者ruby-devel，

如果是在centos等系统下面，执行命令：yum
