我试图让IBM的chaincode_example02工作，但我正在努力解决一些问题。
我与Bluemix启动器网络连接。我等了很长时间才查询，但没有任何成功。现在，我正在阅读对等日志，我有以下问题：
我是否需要在本地go工作目录中添加/导入peer和shim？
launchAndWaitForRegister failed Error starting container: API error (500)是什么意思？

供应商文件夹内容如下所示：
./vendor
./vendor/github.com
./vendor/github.com/hyperledger
./vendor/github.com/hyperledger/fabric
./vendor/github.com/hyperledger/fabric/consensus
./vendor/github.com/hyperledger/fabric/consensus/controller
./vendor/github.com/hyperledger/fabric/consensus/executor
./vendor/github.com/hyperledger/fabric/consensus/helper

./vendor/github.com/hyperledger/fabric/consensus/noops
./vendor/github.com/hyperledger/fabric/consensus/pbft
./vendor/github.com/hyperledger/fabric/consensus/util
........继续.....（基本上是对等和填充码都在这里）
部署将使用chaincode.go + vendor文件夹创建用于链代码执行的docker容器。
您收到的错误是因为找不到构建链代码容器所需的代码。
希望这有帮助！
