Error running the gem: `require': cannot load such file -- mysql-pr (LoadError)

[samuelpismel]

I'm on ruby 2.3.1 and this is the build log:

gem install mysqltopostgres-0.3.0.gem

Fetching: test-unit-2.5.5.gem (100%)
Successfully installed test-unit-2.5.5
Fetching: postgres-pr-0.7.0.gem (100%)
Successfully installed postgres-pr-0.7.0
Fetching: mysql-pr-2.9.11.gem (100%)
Successfully installed mysql-pr-2.9.11
Successfully installed mysqltopostgres-0.3.0
4 gems installed

But when I run the gem this load error appears:
/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/mysqltopostgres-0.3.0/lib/mysql2psql/mysql_reader.rb:4:in 'require': cannot load such file -- mysql-pr (LoadError)

Any ideas how to solve?

Also encountering this error.

I installed from source from inside my Rails app's directory.
Tried gem install mysql-pr from mysql2postgres/ as well as from within my Rails app's directory.

I also tried bundle exec in front but got
gems/mysqltopostgres-0.3.0/lib/mysql2psql/mysql_reader.rb:4:in 'require': cannot load such file -- mysql-pr (LoadError)

ruby 2.3.1, os x 10.11.6

any idea?

This says that the problem is related to mysql2 not being built with native extensions. The answer gives a solution for windows, but I'll have to go and look (again) for the solution for OSX.

any luck resolving this for OSX? I have the same issue: /.rbenv/versions/2.3.3/lib/ruby/gems/2.3.0/gems/mysqltopostgres-0.3.1/lib/mysql2psql/mysql_reader.rb:4:in `require': cannot load such file -- mysql-pr (LoadError)
