Question

我正在尝试从客户端安装fabcar-chaincode。

In line with我已经启动了Fabric-v1.0并创建了频道，然后运行enrollAdmin.js和registerUser.js。

我想使用我创建的installchaincode.js安装fabcar。

但发生了以下错误。

error: [client-utils.js]: sendPeersProposal - Promise is rejected: Error: 2 UNKNOWN: chaincode error (status: 500, message: Authorization for INSTALL has been denied (error-Failed verifying that proposal's creator satisfies local MSP principal during channelless check policy with policy [Admins]: [This identity is not an admin]))
Failed to install proposal :: TypeError: Cannot read property 'status' of undefined

有人可以帮我解决如何从客户端安装链码。

我的代码就是这个。
