[英]Error with gem pg shouldn't happen locally, only in production, why is bundle installing it?
我有一个Ruby on Rails应用程序,刚开始将其部署到Heroku。
Heroku快速入门指南说,要在生产环境中包含数据库的pg gem。 好的,这是我上次部署到Heroku时出现的问题,并通过以下方法解决了该问题:
group :production do
gem 'pg'
end
但是,这一次,当我尝试在本地“捆绑安装”或“捆绑更新”我的应用程序时,出于某种原因尝试安装pg,尽管我明确告诉它只能在生产中使用pg! 这是什么原因,我该怎么解决? 谢谢!
Installing pg (0.13.2) with native extensions
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

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.
尝试跑步
bundle install --without production
这将防止生产宝石被捆绑,并且该设置将对普通捆绑命令有效,直到您下次使用--without
参数时为止。
