Heroku 使用pip和virtualenv在Windows xp上安装psycopg2

我正在关注Heroku的“在Heroku上使用Django入门”文章，并且在“pip安装psycopg2”上遇到了一系列错误。Django 1.5.1和PostgreSQL 9.2.4已经安装，是的，postgres\bin\，\include\目录位于路径上

如何解决此错误？

psycopg2构建脚本调用

pg_config.exe

来发现PostgreSQL

包含
和
lib
目录的位置（因为它需要
libpq fe.h
和
libpq.lib
）

这通常通过将
C:\PostgreSQL\bin
目录添加到
PATH
环境变量中来解决

然而，您的问题似乎是您的PostgreSQL安装了Cygwin，因此pg_配置脚本告诉您使用
/usr/include
，但Visual Studio C编译器试图在
C:\usr\include
中找到它，而它实际上位于Cygwin安装目录下，如
C:\Cygwin\usr\include

一个快速而肮脏的修复方法是将Cygwin
include
和
lib
目录临时复制到
C:\usr
中，然后再次运行pip

或者，您可以安装PostgreSQL windows二进制文件，并将
PATH
变量指向它们，这样使用的pg_config.exe就不会是Cygwin

如果在编译过程中也看到此错误：

error: command 'mt.exe' failed with exit status 31

您必须应用此修复程序：

这是关于添加：

ld_args.append('/MANIFEST')

此行之后的msvc9compiler.py：

ld_args.append('/MANIFESTFILE:' + temp_manifest)

或者您可以避免所有这些，并使用psycopg2预编译的二进制文件。
