Python Heroku Django错误运行应用程序

所以我在这里和其他论坛上尝试了很多东西，什么都没有。所以请帮我解决这类问题。我是python新手，在Django，我创建了一个小应用程序，它使用heroku local命令运行得非常完美，但一旦我将它放到服务器上，我就无法运行它，这是我的回溯：

在应用程序的基本目录中，您有一个

requirements.txt

文件，Heroku使用该文件安装所有需要的库/包

复制用于开发的环境的最简单方法是将cd插入该目录并运行

pip freeze>requirements.txt

。这将创建一个镜像您的开发环境的文件。提交该文件并将其推送到Heroku，Heroku将安装这些软件包及其依赖项

对于此特定错误，添加带有

django crispy forms

的行将负责安装

Heroku documentation

您安装了crispy_表单吗？是的，我安装了，但仍然存在问题您安装了crispy_表单吗？是的，但是仍然有问题，我已经添加了它们：

tail requirements.txt Django==1.9 South==1.0 dj数据库url==0.2.2 dj static==0.0.5 gunicorn==18.0 psycopg2==2.5.1 static==0.4 wsgiref==0.1.2 Django crispy forms

，而在该目录中，

git commit requirements.txt-m“requirements.txt updated”

然后

git-push-heroku-master

（假设您设置了一个名为master的标准git分支）。从这里，您应该看到Heroku的输出，在部署完成后更新您的dyno和一条消息。您的新实例（可能）需要几分钟才能启动。为了测试在Heroku上启动Django应用程序时是否出错，运行

Heroku run python manage.py collectstatic--noinput

是一个不错的选择。我已经用新的输出更新了我的主要问题，没有幸运的是，你仍然有Heroku不知道需要安装的软件包。在这种情况下，您需要将

django registration redux

添加到requirements.txt，提交更改，然后再次推送到Heroku。冻结整个环境要容易得多

cd

到Heroku项目的基本目录，然后运行

pip freeze>requirements.txt

。阅读上面的文档以获得更完整的解释。我没有在

virtualenv

中运行，所以我安装了很多。我会尽量消除不必要的。ThanksI添加了它们：
