Question

当我尝试运行像

这样的简单代码时

# A Postgres connection:
DataMapper.setup(:default, 'postgres://localhost/the_database_name')

在win7 x86-64机器上，我收到以下错误：

我安装了每个gem依赖项和postgreSQL的二进制版本（在他们的站点上找到一键安装程序）我怀疑x86-64架构是导致错误的原因，因为x86机器上的相同安装效果很好。

一些想法？感谢

PS：这是this one之后的一个问题（没有真正回答），但是由于错误是另一个问题，我提出了一个新问题。

Answer 1

我是一名Linux用户，并且在十四年没有在Windows中进行任何编程。但是：

错误消息显示它不是有效的Win32应用程序。而且，它适用于32位安装，对吧？

尝试在64位计算机上安装32位版本的Postgres。它仍然可以在64位机器上运行。否则，可能存在64位Windows库的选项。

Answer 2

有点迟到了，但如果有人在谷歌搜索后结束了这里，我发现这有效：

将这些文件从Postgres安装目录复制到.. \ Ruby \ bin：

LIB \ libpq.dll
bin \ libeay32.dll
bin \ libintl-8.dll
bin \ libiconv-2.dll
bin \ krb5_32.dll
bin \ comerr32.dll
bin \ k5sprt32.dll
bin \ gssapi32.dll

有些可能已经存在，因此您无需覆盖。
