生成锯齿-seth-tp时出现protobuf错误

Question

我开始学习锯齿。最初，我计划在锯齿网络上安装以太坊智能合约。为了在执行此命令后执行this tutorial，docker-compose up --build我收到以下错误，

新答案

此错误现在已修复。PR https://github.com/hyperledger/sawtooth-seth/pull/116已合并。

老答案

您看到的错误是由于最近在处理protobuf文件的方式上更新了sawtooth sdk-go。此PR https://github.com/hyperledger/sawtooth-sdk-go/pull/38中的详细信息。

为了提供更多信息-SDK的src/protobuf应该设置在GOPATH中。此外，应更新代码以开始使用打包的protobuf文件，而不是在每次构建时重新生成它们。

PR https://github.com/hyperledger/sawtooth-seth/pull/116解决了这个问题。请使用它，直到代码合并到主线。
