请帮帮我。

【参考方案1】：

bash: gunicorn: 找不到命令

上面的错误明确提到你在Heroku服务器上没有gunicorn

如何安装

使用pip install gunicorn 安装它会清除错误。 将 gunicorn 添加到您的 requirements.txt 文件中

【讨论】：

在运行上面的命令时，我得到 - 要求已经满足（使用 --upgrade 升级）：gunicorn in /home/dc/.virtualenvs/jango/lib/python2.7/site-packages 清理...

@RahulSatal 更好的调试方式，您可以登录 heroku bash 并运行 pip freeze 以确保 gunicorn 吗？或尝试heroku run pip install gunicorn

是的，它包含 gunicorn==17.5 和 command-heroku run pip install gunicorn ，安装成功

@RahulSatal 没有先生，你能再粘贴一下heroku日志吗？

我已在问题中更新了我的 heroku 日志。请检查一下

【参考方案2】：

您应该安装 django-toolbelt（您可以通过 pip install django-toolbelt 来安装），然后它会安装 gunicorn），然后您需要将其添加到您的 requirements.txt（使用 pip freeze > requirements.txt）。

让我这样解释。 Heroku 查看您的文件结构并搜索两件事： 一个 Procfile 和一个 requirements.txt（如果你有一个 python 项目，如果你有其他项目，这个代表你项目依赖的文件的名称可能有另一个名称，但让我们坚持使用 python django）。

它使用 requirements.txt 的内容来查看需要安装的内容，如果我想要某个库，它需要在该 requirements.txt 中添加（heroku 将安装它知道应该安装的所有内容，并且它知道什么它应该通过查看 requirements.txt 来安装）

然后它查看 Procfile（这个文件告诉它应该运行什么来启动项目）

现在来到你的错误，你可以在那个 prof 文件中写入流动的东西 web: python manage.py runserver 0.0.0.0:$PORT

这意味着：启动一个网络测功机，运行以下命令并使用环境变量$PORT提供的端口 这将使用测试服务器在本地主机上启动 django，以确保它可以正常工作。你不应该在生产中使用它，但调试是好的。

如果你不能让它与它一起工作，这意味着你还有其他问题，而不仅仅是失去了独角兽。

在heroku教程中有一段说：

接下来，使用 pip 安装我们应用程序的依赖项。在这种情况下，我们将安装 django-toolbelt，其中包括我们需要的所有包： Django（网络框架） Gunicorn（WSGI 服务器） dj-database-url（Django 配置助手） dj-static（一个 Django 静态文件服务器）

在此处粘贴您的 requirements.txt，以便我们更快地计算出来。

如果要在 heroku 上使用 Django，请使用 this 。

唯一适合我的解决方案。非常感谢您如此详细的回复。
