Hyperledger Fabric - 无法根据 MagnetoCorp 示例实例化合同

Question

每当我尝试根据 MagnetoCorp example 实例化合约时，我都会收到以下错误。在终端中：

2019-03-06 14:18:49.695 UTC [chaincodeCmd] InitCmdFactory -> INFO 001 Retrieved channel (mychannel) orderer endpoint: orderer.example.com:7050

Error: could not assemble transaction, err proposal response was not successful, error code 500, msg cannot get package for chaincode (papercontract:0)

并且 monitordocker 输出：

唯一对我有意义的行是：

executeDeployOrUpgrade -> ERRO 052 cannot get package for chaincode (papercontract:0)-err:open /var/hyperledger/production/chaincodes/papercontract.0: no such file or directory

因为 /var/hyperledger 目录在我的系统中不存在。

Answer 1

/var/hyperledger/production/chaincodes 文件夹在对等容器的文件系统上，不是您的本地系统。

假设您正在使用本地示例结构，您可以使用类似于以下的命令检查文件夹的内容：

docker exec -it peer0.org1.example.com ls /var/hyperledger/production/chaincodes

这应该会显示您已安装的链代码。希望输出会向您显示您已安装并需要实例化的确切名称和版本，但如果没有，您需要返回到上一步中的 peer chaincode install 命令。
