pggeminstall失败,找不到libpq-fe.h头文件

每当我运行bundle install我的VPS(CentOS Linux版本7.0.1406(Core))时,我在安装pg gem时出错.

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.

我可以用:安装pg standalone,gem install pg -- --with-pg-cOnfig=/usr/pgsql-9.4/bin/pg_config问题解决了.

所以我添加了一个capistrano任务来为部署创建一个./bundle/config,其中build.pg键设置为我的VPS上的pg_config路径.在Capistrano config/deploy.rb这被调用before bundler:install.

desc "Create bundle config"
task :prepare_bundle_config do
  on roles(:app) do
    within release_path do
      execute :bundle, 'config build.pg --with-pg-cOnfig=/usr/pgsql-9.4/bin/pg_config --local'
    end
  end
end

我安装了必要的包:

postgresql94-server.x86_64
postgresql94-devel.x86_64
postgresql94-libs.x86_64
libpqxx.x86_64
libpqxx-devel.x86_64

这是我安装的capistrano*宝石

bundle list | grep capistrano
* capistrano (3.3.5)
* capistrano-bundler (1.1.4)
* capistrano-rails (1.1.2)
* capistrano-rbenv (2.0.3)
* capistrano-stats (1.1.1)

我在这里想要用bundler成功安装pg是什么？如果您需要任何其他信息,请发表评论,我将更新此帖子.

postgres二进制文件不在路径中.将它们符号链接到路径中的目录中,你应该很好:ln -s /usr/pgsql-9.4/bin/p* /usr/local/bin.

你有没有建立postgres或从yum安装它？
