我遵循了商业票据的文档，但是停留在实例化上。
我使用了Fabric 1.4，尝试在线搜索，但没有发现任何人遇到问题，这可能与 Error: ["Missing contract org.hyperledger.fabric in metadata"]
Error: ["Missing contract org.hyperledger.fabric in metadata"]

在解决https://jira.hyperledger.org/browse/FAB-15287之前，目前的解决方法是修改magnetocorp / contract和digibank / contract目录中的package.json文件。查找条目
"dependencies" : { "fabric-contract-api" : "~1.4.0", "fabric-shim": "~1.4.0" },
并~从版本号中删除（tilda），即
~
"dependencies" : { "fabric-contract-api" : "1.4.0", "fabric-shim": "1.4.0" },
这应该将其还原为使用1.4.0而不是1.4.1，在撰写本文时，它是当前的1.4版本，该示例应该可以使用。
