Redmine/Ruby/Rails/Postgresql - cannot load such file -- pg_ext

Question

I'm trying to install redmine-2.3.0 on fedora-18(64-bit). I followed instructions at redmine's official user's guide(http://www.redmine.org/projects/redmine/wiki/RedmineInstall). Everything went well until i run: rake generate_secret_token. I got the following error:

rake aborted! cannot load such file -- pg_ext

I have postgresql-9.2.4-1.

Thanks in advance for any help.

I solved my problem:

Had my *pg_ext.so* file under: /usr/local/share/gems/gems/pg-0.15.1/ext/

Copied it to: /usr/local/share/gems/gems/pg-0.15.1/lib/

I had the same problem and this tip helps. But I don't think that this is a real solution. – Hajo Thelen Jul 13 '13 at 08:00

I got this error only with ruby 2.0.0p247, if I downgrade to p0 there is no problem. – Ivailo Bardarov Jul 30 '13 at 08:41

I only started seeing this on 2.0.0-p247. Check out this output:

>find ~/.rvm/gems -name "pg_ext*"
/Users/jshort/.rvm/gems/ruby-1.9.3-p194/gems/pg-0.14.1/ext/pg_ext.bundle
/Users/jshort/.rvm/gems/ruby-1.9.3-p194/gems/pg-0.14.1/lib/pg_ext.bundle
/Users/jshort/.rvm/gems/ruby-1.9.3-p194/gems/pg-0.16.0/ext/pg_ext.bundle
/Users/jshort/.rvm/gems/ruby-1.9.3-p194/gems/pg-0.16.0/lib/pg_ext.bundle
/Users/jshort/.rvm/gems/ruby-2.0.0-p247/gems/pg-0.16.0/ext/pg_ext.bundle
/Users/jshort/.rvm/gems/ruby-2.0.0-p247/gems/pg-0.16.0/lib/Users/jshort/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/site_ruby/2.0.0/x86_64-darwin11.4.2/pg_ext.bundle

I just copied the pg_ext.bundle to the 2.0.0-p247's lib directory like the 1.9.3 versions.

Also note that odd directory at the end like the gem installer put that in the wrong location.

thanks, that seems to have fixed it for me, now I'm getting a different error — sjobe, Sep 23 '13 at 12:31

also fedora x64 env. mine pg_ext.so was already in /usr/local/share/gems/gems/pg-0.15.1/lib/. I had to edit /usr/local/share/gems/gems/pg-0.15.1/lib/pg.rb and manually specify location of pg_ext:

 require '/usr/local/share/gems/gems/pg-0.15.1/ext/pg_ext.so'

This doesn't appear to relate to the question. If it does please make your explanation clearer. – Nigel B Jul 22 '13 at 18:27
