[英]Gem::Ext::BuildError: ERROR: Failed to build gem native extension. postgresql and ROR
我需要在应用程序ROR中的生产环境中安装postgresql,以便在使用heroku之后使用它,但是当我尝试安装gem'pg'时会触发以下错误。 我是新手,所以我不知道那样做
我正在使用ruby 1.9.3p547(2014-05-14修订版45962)[i686-linux] rails
Rails 3.2.19 Ubuntu 12.04

Make sure that `gem install pg -v '0.17.1'` succeeds before bundling.
您的问题在日志No pg_config... trying anyway.
这个配置与libpq依赖关系有关,当我开始使用rails时遇到了这种问题 ,所以,我认为答案只是按照以下步骤进行
在控制台中运行此命令。
sudo apt-get install libpq-dev
sudo gem install pg
上述解决方案对我不起作用,但这里的说明没有。 我将总结如下:
sudo find / -name "pg_config"
新的pg_config
路径 gem install pg -- --with-pg-config=path/to/pg_config
根据rderoldan1的解决方案,我运行如下(使用Fedora 23):
dnf install libpq-dev
但是我收到了这条消息:
No package libpq-dev available. Error: Unable to find a match.
最初,使用以下命令安装PostgreSQL:
dnf install postgresql-server postgresql-contrib
当我运行which pg_config
我得到了这个:
/usr/bin/which: no pg_config in (/usr/local/heroku/bin:/usr/local/rvm/gems/ruby-2.2.4/bin:/usr/local/rvm/gems/ruby-2.2.4@global/bin:/usr/local/rvm/rubies/ruby-2.2.4/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/usr/local/rvm/bin:/home/mayur/.local/bin:/home/mayur/bin)
所以我用这个命令再次安装了PostgreSQL:
dnf install postgresql-devel
现在,当我运行which pg_config
我得到:
/usr/bin/pg_config
我可以运行bundle install
而不会出现任何错误。
就我而言,我在OSX El Capitan 10.11.5上使用Postgres 9.5.2,Ruby 2.3.0和Rails 4.2.6。 所有这些都正确设置并正常工作,直到我尝试在本地计算机上部署生产环境。 尝试上面的解决方案,虽然它指向了正确的方向,但它们都不适合我。
所以我的问题主要是关于bundler而不是gem install。 为了做到这一点,首先应按照上面的说明再次正确安装宝石。 pg_config的路径可能因Postgres版本而异。
$gem install pg -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.5/bin/pg_config
要捆绑它,您可能需要在捆绑安装之前正确配置它
$bundle config build.pg --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.5/bin/pg_config
You are replacing the current global value of build.pg, which is currently "--with-pg-config=/opt/local/lib/postgresql91/bin/pg_config"
现在您应该能够毫无问题地运行bundle install
。
希望这有帮助。
