Question

我为我的Rails项目有一个名为# conftest.py def pytest_collection_modifyitems(session, config, items): if config.getoption('--flake8'): items[:] = [item for item in items if item.get_marker('flake8')]的上载程序，该上载程序可以接收一个zip文件，然后使用BulkImagesUploader将其上传到S3。一切正常，但是我发现自己必须使用carrierwave gem将文件直接从浏览器上传到S3。

我已按照gem README上的说明进行操作，但是出现错误提示

carrierwave_direct

下面是我的代码

此错误可能是什么原因？

我意识到错误是与Rails使用的雾版本有关。本应使用的版本是fog 2.0，但Gemfile.lock提到的是fog 0.7。

如果其他任何人遇到此错误，请检查您宝石的版本。这很可能是您出错的原因
