I've trying to use the postgres-pr gem on CentOS/Ruby 1.9.2. When I
attempt to run Webrick (or rake update), I get an error saying that it
cannot find the gem "postgres." I'm not sure why, because nowhere in
my Gemfile or database.yml do I refer to anything called "posgres."
Postgres is confusing (to me). I install "pg (0.10.0)" and that is
working for me. I'm currently toying with Rails 3 using Ruby 1.9.2 but
I've done lots of Ruby 2 using Ruby 1.8 and 1.9.1.
If you use the --database=postgresql option when you create your
project, it will have this at the top:
# PostgreSQL. Versions 7.4 and 8.x are supported.
I got the same error using the pr gem... Strange. There is some
dependency somewhere that I can't find.
Is it possible that when you do "gem" you are using a different copy of
Ruby than if you run your rails application?
There is at least one requirement here:
(replace 2.3.5 with your flavor of Rails)
rescue LoadError => e
alias_method :nfields, :num_fields unless
alias_method :ntuples, :num_tuples unless
alias_method :ftype, :type unless self.method_defined?(:ftype)
alias_method :cmd_tuples, :cmdtuples unless
Possible... Thanks for the suggestions. I'll have to try that out.
