安装dm-postgres-adapter gem时出错（找不到PostgreSQL构建环境）

标签： ruby-on-rails ruby postgresql rubygems datamapper

我需要在Windows 7（64位）上使用sinatra和datamapper在Postgres上实现一个小的ruby webapp。为了开始，我通过Rubyinstaller.org安装了Ruby 2.1.7（x64）和DevKit DevKit mingw64-64-4.7.2，并通过官方站点安装了postgresql-9.4.4-3-windows-x64。在this Datamapper guide之后，我首先尝试安装dm-postgres-adapter。

这就是我得到的：

C:\Ruby DevKit>gem install dm-postgres-adapter

ERROR:  Error installing dm-postgres-adapter:

正如错误消息所指出的那样，我试图使用几个配置选项来尝试指定PostgreSQL安装路径，即

gem install -p dm-postgres-adapter -- --with-pgsql-server-dir=C:/Program Files/PostgreSQL/9.4    
gem install -p dm-postgres-adapter -- --with-pgsql-server-include=C:/Program Files/PostgreSQL/9.4/include
gem install -p dm-postgres-adapter -- --with-pgsql-win32-dir=C:/Program Files/PostgreSQL/9.4

但没有改变结果。经过一些研究后我发现在Linux上这个问题通常是通过RPM安装一些postgres-dev软件包来解决的。但是在Windows上该怎么办？

任何帮助将不胜感激！谢谢！

1 个答案:

答案 0 :(得分：0)

嗯，我希望这是一个答案： 在阅读了有关Windows 64位系统下的gem / devkit问题之后，我决定下载/安装32位（x86）的所有内容（postgres，rubyinstaller，devkit）。 dm-postgres-adapter，data_mapper和所有依赖项顺利安装。
