Question

我正在尝试将一个python 2.7.5 Django应用程序部署到heroku，但是当heroku编译项目时我收到错误。具体来说，问题似乎是pip，以及尝试安装时。

我试过的第一个，我得到了这个错误：“没有这样的选择： - 允许所有外部”。

Heroku输出：

PS C:\(...)> git push heroku master

 !     Push rejected, failed to compile Python app

To git@heroku.com:(...).git
 ! [remote rejected] master -> master (pre-receive hook declined)
error: failed to push some refs to 'git@heroku.com:(...).git'

然后，我尝试添加一个指定python版本的runtime.txt文件：

python-2.7.5

之后，当我再次尝试部署时，当Heroku尝试安装pip时，我遇到了一个不同的错误： “没有这样的文件或目录”

heroku给出的输出是：

C:\(...)> git push heroku master

在本地，我使用pip 1.3.1，但heroku使用1.5.5。这可能是问题吗？有什么想法吗？

看起来您正在使用自定义构建包，我猜这是问题 - 您的自定义buildpack没有包含pip。我建议删除你的自定义buildpack，然后再试一次。

您可以通过运行以下命令删除构建包：

heroku config:unset BUILDPACK_URL

将Django应用程序部署到Heroku时找不到Pip
