Django 找不到模版报错" django.template.exceptions.TemplateDoesNotExist: index.html"

解决办法：在setting.py的TEMPLATES‘DIRS'[]加入模版路径

os.path.join(BASE_DIR, 'templates')

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        #os.path.join(BASE_DIR, 'templates')没了这句，
        # 会显示django.template.exceptions.TemplateDoesNotExist: index.html
        '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',
            ],
        },
    },
]
