Can't able to solve load error

Ruby
1

When I run related MySQL program then I got error like:

/home/jaimin/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in
`require’: cannot load such file – mysql (LoadError)

from
/home/jaimin/.rvm/rubies/ruby-2.0.0-p353/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in
require' from jai.rb:2:in’

I installed rubyGem-2.2.2 and I installed MySQl also.

How can I solve this error?

Kind regards.

Can you confirm you actually successfully installed the mysql gem?
Can you show the output of this command:

$ gem list | grep mysql

Output of above command is:

tcp 0 0 localhost:mysql : listen 5342/mysqld

Kind regards.

Please try again, and don’t confuse with netstat !

Try again means, should I installed MySQL again?

don’t confuse with netstat means I am not unserstand what are you want
to say?

Yes, sorry, I think the language is a problem here. What I mean is
that you showed before:

tcp 0 0 localhost:mysql : listen 5342/mysqld

is not the output of what I wrote, it’s the output of netstat. I want
you to run this, and show us the result:

gem list | grep mysql

Jesus.

Yes, I understand that. It is output of netstat.

gem list | grep mysql

When I run above command then output is not display. Cursor shift to
second line like following:

jaimin@ubuntu:~$ gem list | grep mysql
jaimin@ubuntu:~$

Kind regards.

So what are the individual parts of that command doing, and what
should the output, or lack of output, of that command tell us?

In that command:

[1] gem list: When I will run this command then It will load locally
installed gem. So I can see which gems are installed.

[2] grep mysql: used for searching the contents of files for information
that matches particular criteria.

Kind regards.

The program ‘gem’ can be found in the following packages:

  • ruby1.9.1
  • rubygems
    Try: sudo apt-get install

Is it correct output? If yes what should I do?

Thank you.

SMH. Does that look like the “correct output” of the command I
asked you to explain? Hint: did it list the gems on your computer?

What you should do is learn how to set up a computer properly with
the version of Ruby and RubyGems you want, in your path, and
then learn how to install gems in general.

Trying to code before that’s done is simply pointless.

Thanks for your advise. I got answer.

Kind regards.
