使用 Django 模板新建HelloWorld 項目，瀏覽器輸入http://127.0.0.1:8000/ ，頁面輸出 Hello World!

報以下錯誤

Template-loader postmortem

Django tried loading these templates, in this order:

Using engine django:

• django.template.loaders.filesystem.Loader: F:\Python\HelloWorld\hello.html (Source does not exist)
• django.template.loaders.filesystem.Loader: F:\Python\HelloWorld\templates\hello.html (Source does not exist)
• django.template.loaders.app_directories.Loader: D:\Program Files\Python\Python37\lib\site-packages\django-2.2.5-py3.7.egg\django\contrib\admin\templates\hello.html (Source does not exist)
• django.template.loaders.app_directories.Loader: D:\Program Files\Python\Python37\lib\site-packages\django-2.2.5-py3.7.egg\django\contrib\auth\templates\hello.html (Source does not exist)

解決方法：

根據查找資料 應修改 HelloWorld/settings.py 文件中 TEMPLATES 值（修改'DIRS'值）：

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

以下幾種方式都可以：

設置絕對路徑：

'DIRS': ['F:\\Python\\HelloWorld\\HelloWorld\\templates',],

或
'DIRS': [BASE_DIR, "templates",
             os.path.join('F:\\Python\\HelloWorld\\HelloWorld','templates'),],
 相對路徑：     
 'DIRS': [os.path.join(BASE_DIR,'HelloWorld/templates')],
  或      
 'DIRS': [BASE_DIR, "templates",
             os.path.join(BASE_DIR,'HelloWorld/templates'),],
