我是Python，Django和Heroku的新手。我试图按照设置here设置Django Heroku项目的说明进行操作。我陷入了以下命令：
$ pip install django-toolbelt
我收到以下错误

根据此link我应该在安装python-dev之前安装python-psycopg2，libpq-dev，django-toolbelt。
我在Windows机器上。我该如何安装这些依赖项？我尝试用pip安装它们，但这不起作用。
答案 0 :(得分：4)
显然psycopg2安装程序无法在virtualenv环境下工作。我从http://stickpeople.com/projects/python/win-psycopg/
要在虚拟环境中安装本机二进制文件，请使用easy_install：
C:\virtualenv\Scripts\> activate.bat
(virtualenv) C:\virtualenv\Scripts\> easy_install psycopg2-2.5.win32-py2.7-pg9.2.4-release.exe
答案 1 :(得分：0)
此博文似乎对您的案例很有用：
或者您可以找到这些依赖包的Windows端口。
