它说我在 base.html 的第 10 行有一些错误，但这是我第一次遇到这个错误。部署前，运行本地，没有出现过这样的问题。
其他一切运行顺利。我也重新启动了我的控制台，但仍然无法正常工作。
在我检查了您的站点并看到完整的错误消息后，您似乎没有在 AWS_STORAGE_BUCKET_NAME = os.environ.get('AWS_STORAGE_BUCKET_NAME') 的设置中设置 os 环境变量。
如果您阅读网站上的错误消息，您会看到它说：
/app/.heroku/python/lib/python3.9/site-packages/storages/backends/s3boto3.py, line 572, in url
params['Bucket'] = self.bucket.name …
name 'default.jpg'
parameters None
注意参数None部分，表示存储桶名称变量returns none表示你在heroku上的环境设置一定是错误的，os.environ.get('AWS_STORAGE_BUCKET_NAME') 没有返回任何内容。如果您想知道如何在 heroku 上设置环境变量，请查看：https://devcenter.heroku.com/articles/config-vars
修复：
只是 运行 使用 heroku cli 的这个命令：
heroku config:set AWS_STORAGE_BUCKET_NAME=your_name
（请注意，您必须将 your_name 部分替换为您的存储桶名称）
使用 Heroku 正确部署我的应用程序后，我在访问我的个人资料时遇到此错误。
