Answer 1

发生此问题是因为系统在您的通道工件中找不到任何 genesys.block 。

确保已在指定位置生成了genesys.block文件。希望对您有所帮助。

Answer 2

在我们的情况下，它是缺少的文件夹：./channel-artifacts/ .block文件仍会自动创建

Answer 3

在我的情况下（Windows 10）在丢失的文件夹中生成了创世纪图块：

$./byfn.sh down
$../bin/cryptogen generate --config=./crypto-config.yaml

Org1.example.com
Org2.example.com
$../bin/configtxgen --profile TwoOrgsOrdererGenesis –outputBlock./channel- 
artifacts/genesis.block
$./byfn.sh generate
$./byfn.sh up

只需在./byfn.sh up中运行fabric-samples/first-network/即可解决

使用这个分支 repo release-1.4： https://github.com/hyperledger/fabric-samples/tree/release-1.4

$ git clone --branch release-1.4 https://github.com/hyperledger/fabric-samples.git
