在我的previous question我描述了我们的情况：我们的开发人员将在cygwin环境中使用python而不是Windows 7 - 64位，但测试是在构建期间以及在linux上自动执行的。我们遇到了一些cygwin64的麻烦所以现在我们尝试使用python而不是cygwin32。
令人遗憾的是，在安装psycopg2期间，使用64位和32位版本的PostgreSQL 9.2会导致gcc编译错误。 32位版本安装日志：
$ pip install psycopg2

我们安装了cygwin安装包附带的标准Gcc和PostgreSQL库。下一步做什么？
非常感谢你提前： 乔，公众
答案 0 :(得分：1)
与PostgreSQL安装程序捆绑在一起的libpq使用Microsoft Visual Studio作为本机Windows二进制文件进行编译。
如果从Cygwin链接到它恰好工作，这主要是运气。这不是一个好主意。你真的需要使用为Cygwin构建的libpq和Cygwin程序。
坦率地说，我认为你最近只使用本机Windows并完全避开Cygwin会好得多。当你需要类似unix的构建系统时，你可以使用mysw编译器与msys，并且正确编写的Windows兼容代码可以很好地混合mingw和msvc编译的二进制文件。
在您的情况下，我只是install ActivePython或者我会安装stock Python build，然后安装add psycopg2 myself。
