我不明白是什么问题以及我在做什么错，因为我已经成功地遵循了超级编曲文件中的所有步骤....
编辑
我按照this tutorial中提到的所有步骤，但不是使用谷歌身份验证我使用github身份验证。此外，我已将本地主机更改为connection.json文件中的ubuntu droplet以及此命令中的ip
sed -e's / localhost：7051 / peer0.org1.example.com:7051/'-e's / localhost：7053 / peer0.org1.example.com:7053/'-e's / localhost：7054 / ca.org1.example.com:7054/'-e's / localhost：7050 / orderer.example.com:7050 /'<$ HOME/.composer/cards/restadmin@trade-network/connection.json> / tmp /connection.json&& cp -p /tmp/connection.json $HOME/.composer/cards/restadmin@trade-network/
但还没有成功！我现在得到以下错误.....

原因有很多：
您是否在Composer文档中关注过this tutorial？如果完全遵循它将避免上述3个问题。
