我正在使用XAMPP作为PostgreSQL 9.3的安装文件夹。
C:\ XAMPP \ pgsql的\ 9.3
现在我正在尝试使用该目录安装PostgreSQL gem作为参考:
gem install pg -- --with-pg-include="C:\xampp\pgsql\9.3\include" --with-pg-lib="C:\xampp\pgsql\9.3\lib" --with-pg-config="C:\xampp\pgsql\9.3\bin\pg_config"
但是此命令失败,错误如下:
ERROR: Error installing pg:
ERROR: Failed to build gem native extension.
C:/Ruby/Ruby200/bin/ruby.exe extconf.rb --with-pg-include=C:\xampp\pgsql\9.3

当我在pgsql中检查时,实际上有一个名为 libpq.dll 的文件在
中C:\ XAMPP \ pgsql的\ 9.3 \ lib中
那么为什么错误说它无法找到PostgreSQL客户端库(libpq)?
这个错误有什么解决方案吗?
仅供参考,我正在使用:
我正在尝试安装PG Gem版本0.17.1
答案 0 :(得分:3)
作为评论的后续内容,您似乎必须在Windows上使用 32-bit
Postgres。
这很可能与pg
gem与mingw32
一起使用的想法有关,尽管我不完全确定
