我正在使用Apollo和Express作为带有Type-Graphql的服务器和Typescript

Answer 1

此错误的原因是Apollo 2.0的“文件上传”功能。

您可以在以下链接中了解有关此功能的更多信息：

https://www.apollographql.com/blog/file-uploads-with-apollo-server-2-0-5db2f3f60675

'graphql-upload'包的标量类型为Upload，而Apollo服务器也使用'graphql-upload'来处理文件的上传。

也许您可以使用阿波罗的“文件上传”功能来解决此问题，或者重命名来自“ graphql-upload”的上传。

错误：只能有一个名为“上传”的类型-Apollo，Express，Type-Graphql
