(2) Install ruby
According to redmine's official instructions, the Redmine 4.2 version installed in this section requires that the ruby version must be version 2.7.2 or higher, as shown in the following figure:
Figure 7 Redmine official website requirements for ruby version
Ubuntu18.4 uses the apt install ruby-full command to install the ruby package. The latest version can only be installed to version V2.5, which does not meet the requirements for using ruby2.7.2 or higher.
sudo apt install ruby-full
Figure 8 apt intall installs Ruby tools
ruby -v
Figure 9 can only be installed to version V2.5.1
In order to install Ruby 2.7.2 version, this section uses downloading the Ruby source code, compiling and installing. The specific process is as shown in the figure below:
1. Enter the ruby local image download webpage: https://cache.ruby-china.com/pub/ruby/2.7/, and download the 2.7.2 version compressed package, as shown in the figure below:
