解决方法：
使用grpc version 1.10.1 代替之前的1.13.1版本
npm install grpc@1.10.1

docker-compose -f network/fabric/simplenetwork/docker-compose.yaml down;docker rm $(docker ps -aq);docker rmi $(docker images dev* -q)```
解决办法：
和之前搭建fabric环境遇到的问题一样，BAD_REQUEST 经常是当前要创建的channel 已经存在所以会出现这个错误，
我们可以通过docker rm -f $(docker ps -q -a)
移除之前的容器，但是如果不是channnel 已存在的问题 ，暂时就不知道怎么解决了

解决办法：
这个问题算是比较坑的了，在网上找了很久，看到github 有一个一样的问题
https://github.com/hyperledger/caliper/issues/137
有一条评论提到，因为机器性能问题，开启的peer 较多，两分钟不足以在本机上实例化chaincode 但是照着上面的方式修改了
文件：github.com/hyperledger/caliper/src/fabric/e2eUtils.js#211中的request_time 时间
运行后还是没有解决这个问题，经过一天时间，巧合看到一篇文章提到修改文件：github.com/hyperledger/caliper/node_modules/fabric-client/config/default.json
配置文件中的request_time 运行成功
