Heroku Django错误运行应用程序

Question

所以我从这里和其他论坛尝试了很多东西，没有。所以请帮我解决这类问题。我是python和Django中的新手，我创建了一个小应用程序，它运行完美的 heroku local 命令但是一旦我把它放到服务器上我就无法运行它，这是我的追溯：

Answer 1

在您的应用程序的基本级目录中，您有一个requirements.txt文件，Heroku使用该文件来安装所有需要的库/包。

复制用于开发的环境的最简单方法是cd到该目录并运行pip freeze > requirements.txt。这将创建一个镜像您的开发环境的文件。提交并将该文件推送到Heroku，Heroku将安装这些包及其依赖项。

对于此特定错误，添加django-crispy-forms行将负责安装。
