安裝pylibmc時出現Heroku / Django錯誤

Question

嘗試部署到Heroku時，我收到一英里長的錯誤列表。 我遵循他們的指導進行入門，但是顯然它缺乏而且不准確。

我的設置是一個模塊，我的要求是一個文件夾，其中包含針對每個環境的不同.txt文件：

settings/
  base.py
  dev.py
  heroku.py

requirements/
  base.txt
  dev.txt
  heroku.txt

我嘗試在base.txt和heroku.txt（擴展了base.txt）中使用pylibmc==1.2.2 django-pylibmc-sasl==0.2.4部署到Heroku。

錯誤跟蹤（小樣本）：

我發現了這篇相關的文章，這就是試圖將庫添加到base.txt中的想法，但是仍然沒有幫助。

如果Pylibmc存在於requirements.txt中，則會自動得到支持。

擁有所有這些需求文件只是額外的開銷。 查閱十二因子的開發/產品奇偶校驗文章。
