Rails/Ruby/Postgres - LoadError cannot load such file — pg_ext

由 假如想象 提交于 2019-12-08 17:26:24
问题 I am trying to call a Ruby script (which connects to a postgres db) using the rails controller below, however it appears it is having problems loading one of the PG gem files. I have set my require statement to require 'pg' and tried the absolute path as well (require /usr/local/rvm/gems/ruby-1.9.3-p194@railsTest/gems/pg-0.14.0/lib/pg/ ). The file 'pg_ext' is in fact present in the directory. Additionally, I can run the ruby script standalone without any problems (dbrubyscript.rb), however

cannot connect to Postgres (pg) database from my Ruby Script using gem “pg”(This is not rails, just pure ruby)

问题 I downloaded the postgres.app for my Mac OSX machine. I have a rails app that has connected and used the postgres DB that came with the postgres app. Now I am writing a pure Ruby test script (Not Rails, pure Ruby, not even Active Record) to try to connect to the postgres database instance. These are the steps I followed to set this up 1) ran this command on the terminal: gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/MacOS/bin/pg_config 2) Added this code to the test

Can we always fetch date column as string (varchar) with knex and postgres?

由 元气小坏坏 提交于 2019-12-05 20:51:04
I have a column in postgres database with type date . It is a column like birthday, which is just a date and does not need to have a time part. When fetching this column with knex, the result is a javascript Date object. It is presumably doing new Date(row.birthday) , and this is the result that is sent to the client. The problem now is that the value that the client receives is in the standard ISO 8601 format with the time part and the Z . When the client tries to create a new Date object from this string, the client may have an erroneous date value based on where the client is located. For

Cannot install pg gem

由 China☆狼群 提交于 2019-12-04 09:28:24
I finally managed to get the 'pg' gem install after spending hours trying to figure out why it's not working... at the end I entered sudo env ARCHFLAGS="-arch x86_64" gem install pg -v 0.12.2 -- --with-pg-config=/Applications/Postgres.app/Contents/MacOS/bin/pg_config which worked like a charm. But now I still have the same error when I try bundler - so I guess I didn't really solve the problem? Anyway, here's what bundle install is saying: Installing pg (0.12.2) Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. /Users/thomas/.rvm/rubies/ruby-1.9.3-p392/bin/ruby

How can i setup the path for heroku postgresql app?

由 99封情书 提交于 2019-12-04 08:34:25
问题 I just installed the heroku PSQL app (v1.0) and i'm having trouble being able to connect my rails apps using the gem pg "0.1.4". I already added the path PATH="/Applications/Postgres.app/Contents/MacOS/bin:$PATH" to my .profile and my .bashrc files, but nothing seems to allow me to run psql simply by calling "psql". I had success using "psql -h localhost". When i go for "psql" i get: Is the server running locally and accepting connections on Unix domain socket "/var/pgsql_socket/.s.PGSQL.5432
