无法在Windows上安装pg gem [英] Can't install pg gem on Windows

问题描述

我有两个Ruby版本：1.8.7和1.9.2和PostgreSQL 8.3。我不能在任何人上安装pg gem。获取此错误：

I've got 2 Ruby versions: 1.8.7 and 1.9.2 and PostgreSQL 8.3. I cant install pg gem on any of them. Getting this error:

C:/Development/Ruby187/bin/ruby.exe extconf.rb
checking for pg_config... yes
not recorded
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.

Provided configuration options:
 --with-opt-dir
 --without-opt-dir
 --with-opt-include
 --without-opt-include=${opt-dir}/include
 --with-opt-lib
 --without-opt-lib=${opt-dir}/lib
 --with-make-prog
 --without-make-prog
 --srcdir=.
 --curdir
 --ruby=C:/Development/Ruby187/bin/ruby
 --with-pg
 --without-pg
 --with-pg-config
 --without-pg-config
 --with-pg-dir
 --without-pg-dir
 --with-pg-include
 --without-pg-include=${pg-dir}/include
 --with-pg-lib
 --without-pg-lib=${pg-dir}/lib

我知道这是一个常见问题，但我还没有找到任何可行的解决方案......哦，我已经将C：\程序文件（x86）\ PostgreSQL \8.3\bin添加到我的PATH中。

I know it's a common problem, but I haven't found any working solution yet... Oh, I have added C:\Program Files (x86)\PostgreSQL\8.3\bin to my PATH.

推荐答案

您收到的信息清楚地表明您缺少正确安装该宝石的东西：

The message you're getting is a clear indication that you lack something for the correct installation of that gem:

无法创建Makefile，原因是某些原因，可能缺少
必要的库和/或标题。查看mkmf.log文件以获取更多
的详细信息。您可能需要配置选项。

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.

昨天发布的最新版本的pg（0.10.0）没有Windows本地版本，但如果你安装0.9.0它应该安装二进制文件没有问题。

There is no Windows native version of latest release of pg (0.10.0) released yesterday, but if you install 0.9.0 it should install binaries without issues.

无论如何，如果你想安装gem，你需要安装一个构建环境。如果您使用RubyInstaller，那么您需要 DevKit

Anyhow, if you want to install the gem, you need a build environment installed. If you're using RubyInstaller, then you need the DevKit

安装gem只需要提供额外的gem安装选项（例如 - with-pg-dir ）

Installation of the gem will only require you provide additional options to gem installation (like --with-pg-dir)

subst X: "C:\Program Files (x86)\PostgreSQL\8.3"
gem install pg -- --with-pg-dir=X:
subst X: /D
