ValueError: Missing staticfiles manifest entry for 'favicon.png'
ValueError: Missing staticfiles manifest entry for 'favicon.png'
我第一次尝试将我的 django 网络应用程序部署到 heroku，但我一直收到 500 服务器错误。
这是我查看日志时看到的内容：

在我看来问题是这个ValueError: Missing staticfiles manifest entry for 'favicon.png'
但是我在唯一引用 favicon.png 的模板中将其注释掉了。我想知道 settings.py 文件是否有问题。我对此很陌生，我正在使用 whitenoise 加载我的静态文件。也许我搞砸了一些路径：
# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/3.0/howto/static-files/
STATIC_URL = '/static/'
MEDIA_URL = '/media/'
STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static_in_env')]
VENV_PATH = os.path.dirname(BASE_DIR)
STATIC_ROOT = os.path.join(VENV_PATH, 'static_root')
MEDIA_ROOT = os.path.join(VENV_PATH, 'media_root')
# Add configuration for static files storage using whitenoise
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
MIDDLEWARE = [
'whitenoise.middleware.WhiteNoiseMiddleware',
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',

]
这里是我的代码 link 如果你想查看的话：https://github.com/Kaizen91/ProgramaticLearning
关于我哪里出错的任何想法？
我明白为什么这会有点令人困惑，但就 Django 而言，您实际上并没有将其注释掉：
<!-- <link rel="shortcut icon" href="{% static 'favicon.png' %}"> -->
你在它周围添加了 HTML 注释，这意味着浏览器将不再显示它，但 Django 仍会在 HTML 中生成该行，因此它仍然需要处理static 指令。
如果您使用如下所示的 Django template comments，它会起作用：
{# <link rel="shortcut icon" href="{% static 'favicon.png' %}"> #}
在您部署第一个站点时，如果您在设置中暂时注释掉这一行，您可能会发现它更容易：
# Add configuration for static files storage using whitenoise
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
此设置有助于提高您网站的性能，但这意味着任何对丢失的静态文件的引用都会引发错误。启动您的网站可能更容易 运行 一开始没有这个，然后在您确定其他一切正常时再启用它。
我第一次尝试将我的 django 网络应用程序部署到 heroku，但我一直收到 500 服务器错误。
这是我查看日志时看到的内容：

在我看来问题是这个ValueError: Missing staticfiles manifest entry for 'favicon.png'
但是我在唯一引用 favicon.png 的模板中将其注释掉了。我想知道 settings.py 文件是否有问题。我对此很陌生，我正在使用 whitenoise 加载我的静态文件。也许我搞砸了一些路径：
# Static files (CSS, JavaScript, Images)
# https://docs.djangoproject.com/en/3.0/howto/static-files/
STATIC_URL = '/static/'
MEDIA_URL = '/media/'
STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static_in_env')]
VENV_PATH = os.path.dirname(BASE_DIR)
STATIC_ROOT = os.path.join(VENV_PATH, 'static_root')
MEDIA_ROOT = os.path.join(VENV_PATH, 'media_root')
# Add configuration for static files storage using whitenoise
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
MIDDLEWARE = [
'whitenoise.middleware.WhiteNoiseMiddleware',
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',

关于我哪里出错的任何想法？
我明白为什么这会有点令人困惑，但就 Django 而言，您实际上并没有将其注释掉：
<!-- <link rel="shortcut icon" href="{% static 'favicon.png' %}"> -->
你在它周围添加了 HTML 注释，这意味着浏览器将不再显示它，但 Django 仍会在 HTML 中生成该行，因此它仍然需要处理static 指令。
如果您使用如下所示的 Django template comments，它会起作用：
{# <link rel="shortcut icon" href="{% static 'favicon.png' %}"> #}
在您部署第一个站点时，如果您在设置中暂时注释掉这一行，您可能会发现它更容易：
# Add configuration for static files storage using whitenoise
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'
此设置有助于提高您网站的性能，但这意味着任何对丢失的静态文件的引用都会引发错误。启动您的网站可能更容易 运行 一开始没有这个，然后在您确定其他一切正常时再启用它。
