Tabler: Unable to load the EventMachine C extension; To use the pure-ruby reactor, require 'em/pure_ruby'

[hamada147]

I'm using Ruby v2.6.14.1 provided by this command gem -v

I've followed all the instruction provided in the documentation but I'm unable to figure this one.
First I faced some issues because I had two version of a couple of ruby libraries, so I uninstalled them then installed the specific version required.
After fixing this issue I got this one which I'm kind of lost and I don't really get why it is unable to preform the command.
Unable to load the EventMachine C extension; To use the pure-ruby reactor, require 'em/pure_ruby'

I tried to uninstall it using this gem uninstall eventmachine
then reinstall it using this bundle install
but no luck

the following is the complete log file

I was finally able to make it work by doing the following

1. go to this folder C:\Ruby24-x64\lib\ruby\gems\2.4.0\gems\eventmachine-1.2.5-x64-mingw32\lib
2. open this file eventmachine.rb
3. write this
   require 'em/pure_ruby'
   in the first line of code in the file

this will make it work with no issues.
