Question

尝试在 heroku FileNotFoundError: [Errno 2] No such file or directory: '/app/static' 上托管我的 django 项目时遇到此错误这是settings.py：

STATIC_DIR = os.path.join(BASE_DIR, 'static')
STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles')
STATIC_URL = '/static/'
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static'),
]
STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

这是错误：

 File "/app/manage.py", line 22, in <module>
    main()
  File "/app/manage.py", line 18, in main
    execute_from_command_line(sys.argv)

Answer 1

STATICFILES_DIRS、STATIC_ROOT、MEDIA_ROOT 等之间的区别can be confusing。在您的情况下，您可以先删除 settings.py 的第一行，因为 STATIC_DIR is not a Django settings variable。

那么，您问题的实际原因是 Django 的设置变量 STATICFILES_DIRS 中指定的目录不存在：

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static'),
]

在 Heroku 服务器上，此路径为 /app/static，但在您自己的计算机上，它可能位于诸如 $HOME/awesome-django-project/static 之类的位置。在那里创建目录有望解决问题。

或者，您可以完全删除设置 STATICFILES_DIRS 并放置您的静态文件 inside app directories。我个人更喜欢这种方法，因为它使设置更简单，源代码目录更干净。

FileNotFoundError: [Errno 2] 没有这样的文件或目录：'/app/static'
