我正在跑步heroku push master，得到了这个：

            WARNING!
            ========

            You have just installed Django over top of an existing
            installation, without removing it first. Because of this,
            your install may now include extraneous files from a
            previous version that have since been removed from
            Django. This is known to cause a variety of problems. You
            should manually remove the

            /app/.heroku/python/lib/python2.7/site-packages/django

            directory and re-install Django.

        Successfully installed Django-1.5c2

如何删除以前的 Django 包？

更新：我的要求.txt：

https://www.djangoproject.com/download/1.5c2/tarball/**#egg=django**
South==0.7.6
argparse==1.2.1
distribute==0.6.24
dj-database-url==0.2.1
psycopg2==2.4.6
wsgiref==0.1.2
PIL==1.1.7

粗体文本修复了上述警告。

更新 2：由于 Django 1.5 正式发布，我只使用了 pip freeze：

Django==1.5
South==0.7.6
argparse==1.2.1
distribute==0.6.24
dj-database-url==0.2.1
psycopg2==2.4.6
wsgiref==0.1.2
PIL==1.1.7

我遇到了 Heroku 缓存损坏的包并且无法将它们取出的问题。Python buildpack 应该支持刷新此缓存（CACHE_DIR），但它没有。

有一种解决方法：按照这些说明将您的 Python 运行时更改为例如 3.3.0（您的应用程序是否实际支持 Python 3 并不重要）。然后将其更改回默认值。更改 Python 运行时然后部署的行为将强制 buildpack 完全擦除缓存。据我所知，这是目前擦除缓存的唯一实用方法。

将当前 virtenv 包推送到文件

pip freeze > requirements.txt

犯罪

git commit -am 'update packages'

并推到heroku

git push heroku

然后heroku将重建环境

以为我删除了故障包和所有其他依赖它的包，但没有。每次部署时，我都会不断收到错误消息。最后，我以某种方式删除了依赖于故障包的所有其他包，一切正常。希望有人会发现这很有用
