问题

Question

我正在使用Eve制作REST API。 Eve在Docker容器上运行Nginx和uwsgi。

Python版：3.6.5

夏娃：0.8

Eve-SQLAlchemy ：0.5.0

当我发送资源和项目的GET请求时，没有问题。但是，当我发送PATCH或DELETE请求时，API服务器返回Nginx的默认50xError页面。

日志是这样的：

当我从请求中删除身份验证时，服务器返回＆＃34;请提供正确的凭据，＆＃34;但是当我删除＆＃34; If-Match＆＃34;来自请求的标头，服务器返回此错误。（因此，认证和etag验证之间存在的某些过程可能是导致此错误的原因。

问题

它几乎肯定与Eve和Eve-SQLAlchemy之间的版本不兼容有关。 Eve-SQLAlchemy 0.5仅支持Eve 0.6 ，目前还没有支持更新Eve版本的版本。

这也与您看到的TypeError匹配：find_one()是数据层中的一种方法，Eve-SQLAlchemy提供了该方法。可能在Eve 0.7或0.8中界面发生了变化。

从这里去哪里

如果您正在使用pip，则pip check应报告您的安装错误，因为Eve-SQLAlchemy声明它取决于Eve>=0.6,<0.7（请参阅https://github.com/pyeve/eve-sqlalchemy/blob/586cec403daabaeab8f7cbe133275d5fcc4e4bf3/setup.py#L35）。

要解决此问题，请在您的setup.py和/或requirements.txt中移除任何不相关的Eve版本，或者如果这不会改变任何内容，请添加Eve<0.7。不幸的是，pip并不总能为所有依赖项本身确定一组非矛盾的版本，因此有时需要指导。
