Question

我试图在rails和postgres上使用ruby设置我的VPS（CentOS 6.4）。

我安装了ruby（2.1.0p0），rails（4.1.0）和postgresql（9.3.4）没有问题。

当我尝试创建新的rails应用程序（rails new new_app -d postgresql）时，它会在安装pg gem时停止。我已经查看了有关此错误的所有SO帖子，并尝试了我能找到的所有内容。最建议的是运行＆＃34; yum install postgresql-devel＆＃34;并且仍然没有工作。

您可以在下面找到ssh输出和mkmf.log。如果需要更多信息，请告诉我......

Answer 1

<强>之前：

对于Centos 6 ：使用此guide右键安装Postgres 9. *。

<强>后：

yum install postgresql-libs postgresql-devel

Answer 2

由于您没有使用CentOS 6附带的过时PostgreSQL版本（PostgreSQL 8.4），您需要安装与您的版本匹配的-devel软件包（PostgreSQL 9.X）。

最简单的方法是使用official PostgreSQL yum repository。

由于最新版本是9.5并且它与所有9.X版本兼容，我将编写该版本的说明。将来您可以参考official instructions获取更新的命令。

yum install http://yum.postgresql.org/9.5/redhat/rhel-7-x86_64/pgdg-redhat95-9.5-2.noarch.rpm
yum install postgresql95-devel

然后使用-with-pg-config选项安装gem：

gem install pg -- --with-pg-config=/usr/pgsql-9.5/bin/pg_config

Answer 3

这对我来说更容易：

 codMsgBox "here is your numbers" & " " & tmp1 & " " & tmp2 & " " & tmp3
End Sube

Answer 4

尝试这样的事情;

before "bundle:install" do
  run "ls -l #{fetch(:latest_release)}/Gemfile"
  #run "bundle config  --local --gemfile=#{fetch(:latest_release)}/Gemfile build.pg --with-pg-config=/usr/pgsql-9.1/bin/pg_config"
  run "cd #{fetch(:latest_release)} && bundle config build.pg --with-pg-config=/usr/pgsql-9.3/bin/pg_config"
end

Answer 5

您可以尝试使用postres pg_config文件路径选项安装pg gem：

gem install pg -- --with-pg-config=/usr/pgsql-9.2/bin/pg_config

请根据您的系统更新路径

此致

Answer 6

我的mac上遇到了这个问题，这是一个bash / RVM问题。我不得不把它添加到我的bash： [[-s“$ HOME / .rvm / scripts / rvm”]]＆amp;＆amp;源“$ HOME / .rvm / scripts / rvm”。鉴于它正在查找配置文件，我会调查一下。

在CentOS 6上安装pg gem
