【问题描述】：

我在 heliohost.org (Johnny Server) 有一个帐户，我正在拼命尝试部署一个最简单的 Django 应用程序，但没有任何成功。它实际上是一个非常简单的测试应用程序，可以检查一切是否正常，但事实并非如此。

有几个错误日志：

这些是最重要的文件内容：

views.py：

从 django.http 导入 HttpResponse 导入日期时间从操作系统导入系统，uname 从 django.template 导入模板，上下文从 django.template.loader 导入 get_template

类通知（对象）：

def __init__(self):

    self.so = uname().sysname
    self.version = uname().version
    self.distro = uname().release

informe = Informe()

doc_externo = get_template('informeso.html')

dicc = {"so": informe.so, "version": informe.version,

return HttpResponse(documento)

虽然我刚刚意识到我正在尝试部署一个 Python / Django 应用程序，该应用程序引用了一些在 Heliohost.org 上可能不可用的模块，因为这个站点不允许 shell 访问，如果你出现请告诉我与问题。

非常感谢您。

【解决方案1】：

尝试将ALLOWED_HOSTS = [] 更改为

ALLOWED_HOSTS = ['*']

【讨论】：

【解决方案2】：

感谢您的回答。我已经尝试过了，它给出了另一个错误，说它找不到代码中引用的模板。我已经修改了代码中的路径以及目录结构。

【解决方案3】：

我已经通过指定html文档的绝对路径而不是相对路径来解决它。非常感谢您的帮助。 :-)
