無法使用python virtualenv安裝django-toolkit

Question

我是Python，Django和Heroku的新手。 我試圖遵循有關在此處設置Django Heroku項目的說明。 我陷入以下命令：

$ pip install django-toolbelt

我收到以下錯誤

根據此鏈接，我應該在安裝django-toolbelt之前先安裝python-dev ， python-psycopg2和libpq-dev 。

我在Windows機器上。 如何安裝這些依賴項？ 我嘗試用pip安裝它們，但是不起作用。

Answer 1

顯然， psycopg2安裝程序無法在virtualenv環境下工作。 我從http://stickpeople.com/projects/python/win-psycopg/下載了可執行二進制文件

要在虛擬環境中安裝本機二進制文件，請使用easy_install：

C:\virtualenv\Scripts\> activate.bat
(virtualenv) C:\virtualenv\Scripts\> easy_install psycopg2-2.5.win32-py2.7-pg9.2.4-release.exe

Answer 2

這篇博客文章似乎對您的案例有用：

http://www.swarley.me.uk/blog/2014/02/24/create-a-django-development-environment-on-64-bit-windows-for-heroku-deployment/

或者，您可以僅找到這些依賴項程序包的Windows端口。
