Question

我一直在关注https://hyperledger-fabric.readthedocs.io/en/release-1.4/tutorial/commercial_paper.html

中的商业论文教程

当我通过运行以下命令实例化链码时

docker exec cliMagnetoCorp peer chaincode instantiate -n papercontract -v 0 -l node -c '{"Args":["org.papernet.commercialpaper:instantiate"]}' -C mychannel -P "AND ('Org1MSP.member')"

几分钟后出现以下错误

Error: could not assemble transaction, err proposal response was not successful, error code 500, msg timeout expired while starting chaincode papercontract:0 for transaction

我一直在挖掘一点，看来“ dev-peer0.org1.example.com-papercontract-0”失败了

dev-peer0.org1.example.com-papercontract-0日志显示以下内容：

dev-peer0.org1.example.com-papercontract-0|npm ERR! path /usr/local/src/package.json
dev-peer0.org1.example.com-papercontract-0|npm ERR! code ENOENT

已经坚持了两天，将不胜感激！

编辑：在此之前的步骤按预期顺利进行。同样，第一个网络仿真（./byfn.sh up）运行得很好。

您需要在chaincode目录内的package.json。例如，chaincode目录名称为：./Chaincode，内部应为chaincode.js和package.json。首先，在package.json中的脚本中，放置“节点chaincode.js”。那是因为对等方使用npm开始执行链码。
