无法获取发现服务：无法获取chConfig缓存参考：读取通道对等体的配置失败

Question

当尝试安装和实例化链码时，出现以下错误：

WSL（Linux的Windows子系统）上出现错误

  

无法安装和实例化链码：无法实例化链码：无法获取发现服务：无法获取chConfig缓存参考：读取通道对等体的配置失败

Ubuntu 16.04错误

  

无法安装和实例化链码：无法实例化链码：无法获取发现服务：无法获取chConfig缓存参考：没有为通道[mychannel]配置通道对等体

我正在关注chainHero示例。下面是运行make命令后的完整输出。

Answer 1

您使用错误的通道名称来实例化链码，在config.yaml中，您定义了与对等方peer0，peer1一起使用的通道OneOrgChannel。但是，您似乎正在使用通道mychannel来实例化链码。

将频道名称更改为OneOrgChannel或在config.yaml中添加mychannel。
