gem install pg --with-pg-config工作，捆绑失败 [英] gem install pg --with-pg-config works, bundle fails

问题描述

当我运行（以root身份）

  gem install pg -v'0.12.0' -  --with-pg -config = / usr / pgsql-9.1 / bin / pg_config 
  

我得到以下输出： p>

 ＃ - > gem instal pg -v'0.12.0' -  --with-pg-config = / usr / pgsql-9.1 / bin / pg_config 
构建原生扩展。这可能需要一段时间... 
已成功安装pg-0.12.0 
 1已安装gem 
安装ri文档为pg-0.12.0 ... 
安装RDoc文档pg-0.12.0 ... 
＃ - > 
  

运行bundle install时：

 使用本机扩展安装pg（0.12.0）
 Gem :: Installer :: ExtensionBuildError：错误：无法构建gem本机扩展。

检查pg_config ... no 
否pg_config ..无论如何尝试。如果构建失败，请再次尝试使用
 --with-pg-config = / path / to / pg_config 
检查libpq-fe.h ... no 
无法找到'libpq-fe.h头文件
 *** extconf.rb失败*** 
由于某种原因无法创建Makefile，可能缺少
必需的库和/或头文件。查看mkmf.log文件以获取更多
的详细信息。您可能需要配置选项。 
 
提供的配置选项：
 --with-opt-dir 
 --with-opt-include 
 --without-opt-include = $ {opt- dir} / include 
 --with-opt-lib 
 --without-opt-lib = $ {opt-dir} / lib 
 --with-make-prog 
 --without-make-prog 
 --srcdir =。 
 --curdir 
 --ruby = / usr / local / rvm / rubies / ruby​​-1.9.2-p290 / bin / ruby​​ 
 --with-pg 
  - without-pg 
 --with-pg-dir 
 --without-pg-dir 
 --with-pg-include 
 --without-pg-include = $ { pg-dir} / include 
 --with-pg-lib 
 --without-pg-lib = $ {pg-dir} / lib 
 --with-pg-config 
 --without-pg-config 
 --with-pg_config 
 --without-pg_config 
 
 
 Gem文件将保持安装在/ var / www / simpletrac / vendor / cache / ruby​​ / 1.9.1 / gems / pg-0.12.0进行检查。 
结果记录到/var/www/simpletrac/vendor/cache/ruby/1.9.1/gems/pg-0.12.0/ext/gem_make.out 
安装pg时发生错误（0.12。 0），Bundler无法继续。 
确保在捆绑之前`gem install pg -v'0.12.0'`成功。 
  

我在/usr/pgsql-9.1/include/libpq-fe上安装了libpq-fe.h 。H。所以，我试过了

  gem install pg -v'0.12.0' -  --with-pg-config = / usr /pgsql-9.1/bin/pg_config --with-pg-lib = / usr / pgsql-9.1 / include / libpq-fe.h但仍然不行。 
  

任何帮助都将不胜感激。

另外，我安装了postgresql91-devel和ruby-devel。运行CentOS 6.

解决方案

您是否在运行 bundle install ？

  bundle config build.pg --with-pg-config = / usr / pgsql-9.1 / bin / pg_config 
  

请参阅 http://bundler.io/v1.3/bundle_config.html

WhenI run (as root)

gem install pg -v '0.12.0' -- --with-pg-config=/usr/pgsql-9.1/bin/pg_config

I get the following output:

#-> gem instal pg -v '0.12.0' -- --with-pg-config=/usr/pgsql-9.1/bin/pg_config

When I run bundle install:

Gem files will remain installed in /var/www/simpletrac/vendor/cache/ruby/1.9.1/gems/pg-    0.12.0 for inspection.

An error occured while installing pg (0.12.0), and Bundler cannot continue.
Make sure that `gem install pg -v '0.12.0'` succeeds before bundling.

I have libpq-fe.h installed at /usr/pgsql-9.1/include/libpq-fe.h. So, I tried

gem install pg -v '0.12.0' -- --with-pg-config=/usr/pgsql-9.1/bin/pg_config --with-pg-lib=/usr/pgsql-9.1/include/libpq-fe.h but still no go. 

Any help would be greatly appreciated.

Also, I have installed postgresql91-devel and ruby-devel. Running CentOS 6.

解决方案

Have you tried running this before running bundle install?

bundle config build.pg --with-pg-config=/usr/pgsql-9.1/bin/pg_config
