【中文标题】尝试将我的应用程序推送到 heroku 时出现此错误 FileNotFoundError: [Errno 2] No such file or directory: \'/app/gettingstarted/media\'【英文标题】：Trying to push my app to heroku gives me this error FileNotFoundError: [Errno 2] No such file or directory: '/app/gettingstarted/media'尝试将我的应用程序推送到 heroku 时出现此错误 FileNotFoundError: [Errno 2] No such file or directory: '/app/gettingstarted/media' 【发布时间】：2016-07-26 07:40:27 【问题描述】：

在尝试推送我的应用时出现以下错误

FileNotFoundError: [Errno 2] No such file or directory: '/app/gettingstarted/media'

但它确实存在让我感到困惑。导致它的文件结构是这样的

src/gettingstarted/媒体

媒体是一个空目录。昨晚我的推力还在工作。这是我运行 git push heroku master 的结果

在阅读了这里的帖子后，我运行了这个

 heroku config:set DEBUG_COLLECTSTATIC=1

得到以下输出

不太清楚发生了什么，因为我在 django 上大约有 4 个月的时间。任何帮助或指导将不胜感激

不确定白噪声是否导致此问题。我对此表示怀疑。但这是我的 settings.py 文件

    MEDIA_URL = '/media/'

    # Extra places for collectstatic to find static files.
    STATICFILES_DIRS = (

    )

    # Simplified static file serving.
    # https://warehouse.python.org/project/whitenoise/
    STATICFILES_STORAGE = 'whitenoise.django.GzipManifestStaticFilesStorage'

我的入门/urls.py

        urlpatterns = [
        url(r'^admin/', include(admin.site.urls)),
        url(r'^blog/', include('hello.urls', namespace='blog', app_name='blog')),
        url(r'^db', hello.views.db, name='db'),
        url(r'^', include('hello.urls')), # hello corresponds to the hello module in installed apps
    ]

    if settings.DEBUG:
        urlpatterns += static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
        urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

【问题讨论】：

【参考方案1】：

我认为这里的问题是 git 不跟踪空目录，它们需要包含至少一个文件让 git “看到”它们，所以虽然你的 media 目录存在于本地，但它在 Heroku 上不存在.处理此问题的常用方法是在目录中创建一个名为 .keep 的空文件。

【讨论】：

就是这样。我添加了 .keep 文件。然后我将其删除以确保它不是侥幸它不起作用。我把它加回来，它工作。谢谢
