Error installing Redmine (cannot load such file -- mysql2/mysql2)

Added by System Administrator over 11 years ago

Hello!

Initially tried on a 32-bit OS CentOS 6.4, now trying to install on 64-bit CentOS 6.4

The error occurs in the command:

# rake generate_secret_token
rake aborted!
cannot load such file -- mysql2/mysql2
/var/lib/redmine/config/application.rb:7:in `<top (required)>'
/var/lib/redmine/Rakefile:5:in `<top (required)>'
(See full trace by running task with --trace)

Actually seems to be all installed correctly:

# gem list

Tell me where to dig out what the problem might be?

I had the same issue

I believe that what solved the issue for me was to remove all the gems, then install bundler via yum (yum install rubygem-bundler)
then run 'bundle install --without development test' again.

Not sure this did the trick though, had several issues

RE: Error installing Redmine (cannot load such file -- mysql2/mysql2) - Added by Home chee about 11 years ago

I had the exactly same issue.

the version:

#ruby -v
ruby 2.0.0p247 (2013-06-27) [x86_64-linux]

#gem -v
1.8.25

#rails -v
Rails 3.2.15

and it is on Ubuntu OS.

I didn't know what the problem is and how to solve it.
Maybe there are some problems with the mysql installing? I'm not sure.

have you got the problem solved now?

I resolved my problem by referring a page below:
http://stackoverflow.com/questions/8707293/rails-3-no-such-file-to-load-mysql2-mysql2-in-production

It seems mysql2 libs installed wrong place.
You will get it, after reinstall mysql2.

Could you try this way.
I hope this will answer your needs.

Best Regard.
