【问题描述】：

我用命令禁用collectstatic

heroku config:set DISABLE_COLLECTSTATIC=1

成功将我的项目推送到 Heroku 后，手动 collectstatic 如下：

$ heroku run python manage.py collectstatic

不幸的是，Heroku 报告错误涉及manage.py

    STATIC_ROOT = (BASE_DIR, "staticfiles")
    STATICFILES_DIRS = (
        os.path.join(BASE_DIR, 'static'),
    )

如何解决这样的问题？

【解决方案1】：

错误在您的STATIC_ROOT 设置中。正如错误消息所述，您传递的是元组而不是路径：

STATIC_ROOT = (BASE_DIR, "staticfiles")

改成：

STATIC_ROOT = os.path.join(BASE_DIR, "staticfiles")
