我使用 XAMPP 作为 PostgreSQL 9.3 的安装文件夹.
I'm using XAMPP as my installation folder for PostgreSQL 9.3.
C:\xampp\pgsql\9.3
C:\xampp\pgsql\9.3
现在我正在尝试使用该目录作为参考安装 PostgreSQL gem:
And now I'm trying to install PostgreSQL gem using that directory as a reference:
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"但是这个命令失败了,错误如下:
But this command failed with errors listed below:

When I checked inside pgsql, there was actually a file named libpq.dll inside of
C:\xampp\pgsql\9.3\lib
C:\xampp\pgsql\9.3\lib
那为什么报错说找不到PostgreSQL客户端库(libpq)??有没有针对此错误的解决方案?仅供参考,我正在使用:
So why did the error say it couldn't find the PostgreSQL client library (libpq)?? Is there any solutions for this error? FYI, I'm using:
- Windows 8.1 64 位
- Ruby 2.0.0 64 位
- Rails 4.1.1
- Devkit 4.7.2 64 位
- PostgreSQL 9.3.4 64 位
我正在尝试安装 PG Gem 0.17.1 版
And I'm trying to install PG Gem version 0.17.1
推荐答案作为评论的后续,看来你必须使用32-bit Windows 上的 Postgres.
As a follow-up to the comments, it looks like you've got to use 32-bit Postgres on Windows.
这很可能与 pg gem 与 mingw32 一起工作的想法有关,尽管我不完全确定
This is most likely to do with the idea that the pg gem works with mingw32, although I'm not totally sure
