在用configtxgen tool创建创世区块时，报错：While parsing config: yaml: unknown anchor ‘OrdererDefaults‘ referenced

在执行以下命令生成创世区块时，出现报错！

生成创世区块命令：

         ./bin/configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./genesis.block 

报错信息：

 在Stack Overflow找到解决方案：

In YAML all anchors ( those tokens starting with &) need to precede any references to them (using aliases, the tokens starting with *) in the file.

So in the root-level mapping you should put your key Profiles and its value after the key Organizations, Orderer and Application (and their values):

应该将configtx.yaml文件中Profiles的部分放置到最后，原因如上：
