我刚刚升级到Rails 3.1和我尝试部署到Heroku的第一个应用程序遇到与Postgres适配器相关的问题。我可以推送应用程序到heroku,但当我尝试迁移数据库时,我得到以下错误:
heroku rake db:migrate rake aborted! Please install the postgresql adapter: `gem install activerecord-postgresql-adapter` (pg is not part of the bundle. Add it to Gemfile.) Tasks: TOP => db:migrate => db:load_config (See full trace by running task with --trace) 当我尝试他们建议安装我得到: ERROR: Could not find a valid gem 'activerecord-postgresql-adapter' (>= 0) in any repository ERROR: Possible alternatives: activerecord-postgis-adapter,activerecord-jdbcpostgresql-adapter,activerecord-postgresql-cursors,activerecord-jdbcmysql-adapter,activerecord-jdbcmssql-adapter 这已经看起来很奇怪…所以什么精确的gem应该安装,以获得这个东西工作,如果不是他们说什么我应该安装? 当我尝试安装gem pg我获得: Building native extensions. This could take a while... ERROR: Error installing pg: ERROR: Failed to build gem native extension. /Users/jerometufte/.rvm/rubies/ruby-1.9.2-p180/bin/ruby extconf.rb checking for pg_config... no No pg_config... trying anyway. If building fails,please try again with --with-pg-config=/path/to/pg_config checking for libpq-fe.h... no Can't find the 'libpq-fe.h header *** extconf.rb failed *** Could not create Makefile due to some reason,probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. Provided configuration options: --with-opt-dir ... 我目前使用SQLite3。任何帮助非常感谢,这是令人不安的我。
选项1:
添加pg到您的Gemfile但跳过尝试在本地安装。 $ cat Gemfile ... group :production do # gems specifically for Heroku go here gem "pg" end # Skip attempting to install the pg gem $ bundle install --without production 选项2(Debian / Ubuntu): 将pg添加到Gemfile,但首先安装先决条件。 $ cat Gemfile ... group :production do # gems specifically for Heroku go here gem "pg" end # Install the pg gem's dependencies first $ sudo apt-get install libpq-dev # Then install the pg gem along with all the other gems $ bundle install (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
