在Heroku上手动删除Python包(Manually remove Python package

我正在运行heroku push master ，并得到了这一点：

 ----- Python app detected
 ----- No runtime.txt provided; assuming python-2.7.3.
 ----- Using Python runtime (python-2.7.3)
 ----- Installing dependencies using Pip (1.2.1)

            ========
            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

我怎样才能删除以前的Django的包？

UPDATE：我requirements.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

粗体文字固定上述警告。

更新2：由于Django的1.5正式发布，我只是用PIP冻结：

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

Answer 1:

其中，Heroku的缓存破包，有没有办法让出来我有问题。 Python的buildpack应该有某种冲厕这个缓存（cache_dir里）的支持，但事实并非如此。

有一种变通方法：遵循这些说明你的Python运行时改变，例如，3.3.0（这并不重要，如果你的应用程序实际上支持Python 3与否）。 然后改回为默认值。 改变你的Python运行，然后部署将迫使buildpack彻底删除缓存的行为。 据我所知，这是抹去此刻的高速缓存中的唯一可行的方法。

Answer 2:

目前推包virtenv到文件

pip freeze > requirements.txt

承诺

git commit -am 'update packages'

而推的Heroku

git push heroku

而herocu重建环境
