超分类器锯齿键生成问题

Question

我安装了hyperledger-sawtooth。

我输入命令sawtooth keygen my_key来创建键，但是我得到了以下错误：

$ sawtooth keygen my_key

Answer 1

我只使用这两个命令

sudo apt-get update
sudo apt update

它起了作用

Answer 2

这一问题的发生是由于许多锯齿论坛上列出的过时的原型。运行以下命令，查看protobuf是否需要升级。

 sudo apt list --upgradable

如果列出了python3-probuf，请运行以下命令。

sudo apt install python3-protobuf
