在Heroku中获得正确的依赖项

Question

我正在尝试让Heroku参加一个具有pip要求的editable dependency (即-e git://github.com/merlinares/django-registration.git#egg=django-registration)。

然而，尽管它看起来在部署时采用了这个分支，但它实际上并没有使用它。我已经用heroku run cat .heroku/python/lib/python2.7/site-packages/registration/forms.py检查了站点包中的代码，它没有包含新的代码，而只是使用了之前安装的默认django注册包。

但是，派生版本似乎存在于django-registration.egg-link指定的目录中，该目录名为：

/app/.heroku/src/django-registration

在deploy (即git push heroku master)上，我看到：

-----> Installing dependencies using Pip (1.3.1)

   Obtaining django-registration from git+git://github.com/mattlinares/django-registration.git#egg=django-registration (from -r requirements.txt (line 12))
     Updating ./.heroku/src/django-registration clone
     Running setup.py egg_info for package django-registration

     Running setup.py develop for django-registration

       Creating /app/.heroku/python/lib/python2.7/site-packages/django-registration.egg-link (link to .)

       Installed /app/.heroku/src/django-registration
   Successfully installed django-insensitive django-registration
   Cleaning up...

我还手动尝试卸载并安装了那个特定的fork，效果如下：

(ssc)~/code/django/ssc: heroku run pip install --upgrade git+git://github.com/mattlinares/django-registration.git
Running `pip install --upgrade git+git://github.com/mattlinares/django-registration.git` attached to terminal... up, run.5704

  Cloning git://github.com/mattlinares/django-registration.git to /tmp/pip-qpTF2t-build
  Running setup.py egg_info for package from git+git://github.com/mattlinares/django-registration.git

  Found existing installation: django-registration 0.8-alpha-1
    Uninstalling django-registration:
      Successfully uninstalled django-registration
  Running setup.py install for django-registration

Successfully installed django-registration
Cleaning up...

然而，我的应用程序并没有使用我试图提供给它的registration版本。我怀疑和heroku run ls .heroku/python/lib/python2.7/site-packages一起列出的鸡蛋

django_registration-0.8-py2.7.egg-info        registration

django-registration.egg-link

我还尝试按照how to pip uninstall with virtualenv on heroku cedar stack?清除整个虚拟环境，但没有成功

我能做什么?

当使用可编辑的依赖项时，您必须定义一个标记或提交散列。

按照您的示例进行操作：

-e git+https://github.com/merlinares/django-registration.git@3.1#egg=django-registration

或

-e git+https://github.com/merlinares/django-registration.git@40fee813ca444236da6d66f516b869fd8ebbe9cd#egg=django-registration
