将Django应用部署到Heroku时找不到点

Question

我正在尝试将python 2.7.5 Django应用程序部署到heroku，但是在heroku编译项目时遇到错误。 具体来说，问题似乎出在pip上以及尝试安装时。

我尝试的第一个错误是：“没有这样的选择：--allow-all-external”。

Heroku输出：

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

no such option: --allow-all-external

 !     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，我尝试添加指定python版本的runtime.txt文件：

python-2.7.5

之后，当我尝试再次进行部署时，Heroku尝试安装pip时出现了一个不同的错误：“没有这样的文件或目录”

heroku给出的输出是这样的：

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？

看来您使用的是自定义构建包，而我猜这就是问题所在-您的自定义构建包中没有pip。 我建议删除您的自定义buildpack，然后重试。

您可以通过运行以下命令删除构建包：

heroku config:unset BUILDPACK_URL
