<a href="http://www.pip-installer.org/en/1.1/usage.html#alternate-package-repositories" rel="nofollow">This section of the documentation</a> for an older version of PIP suggests that if PIP finds multiple definitions for a package (e.g. via <code>--extra-index-url</code> or <code>--find-links</code>), the last match will be used. Unfortunately, I cannot find this information in the current documentation, so it may have changed.

Perhaps something like this in your requirements file will work:

<pre><code>...
django-photologue
...

--find-links https://github.com/jdriscoll/django-photologue
</code></pre>

just use the <code>-U</code> or <code>--upgrade</code> option to replace the original package in your venv with your custom version:

<pre><code>cd myapp &amp;&amp; venv/bin/pip install -U git+https://github.com/jcomeauictx/django-crispy-forms.git
</code></pre>

then in your requirements.txt replace the line

<pre><code>django-crispy-forms==1.4.0
</code></pre>

with

<pre><code>git+https://github.com/jcomeauictx/django-crispy-forms.git
</code></pre>

when you push to your heroku instance, you should see something like:

<pre><code>-----&gt; Deleting 1 files matching .slugignore patterns.
-----&gt; Python app detected
-----&gt; Uninstalling stale dependencies
 Uninstalling django-crispy-forms-1.4.0:

I am building an app that uses <code>photologue</code> and a few other packages that have <code>photologue</code> as a dependency (e.g., <code>cmsplugin-photologue</code>). However, I need to use a modified version of <code>photologue</code> hosted on github. All this will then be deployed on Heroku, which means that installations of dependencies is done solely through a <code>requirements.txt</code> file.

In principle this is done quite easily: I can just add the repository to the requirements file as described <a href="https://devcenter.heroku.com/articles/python-pip#git-backed-distributions" rel="nofollow">here</a> and it will be installed. The problem is that the original <code>photologue</code> is installed too and ends up the one being used.

So the general question is: Using <code>pip</code>, how can I replace an application that is a dependency of several apps with my own version of that application?

我正在构建一个应用程序，它使用photologue和其他一些将photologue作为依赖项的包(例如，cmsplugin-photologue)。但是，我需要使用托管在github上的photologue的修改版本。所有这些都将部署在Heroku上，这意味着依赖项的安装仅通过requirements.txt文件完成。...
