在尝试Demo的时候遇到了不少坑，这里记录一下：
问题一
在执行./startFabric.sh时报错ERROR: manifest for hyperledger/fabric-couchdb:latest not found
# don't rewrite paths for Windows Git Bash users
export MSYS_NO_PATHCONV=1
docker-compose -f docker-compose.yml down
Removing network net_basic
docker-compose -f docker-compose.yml up -d ca.example.com orderer.example.com peer0.org1.example.com couchdb
Creating network "net_basic" with the default driver
Pulling couchdb (hyperledger/fabric-couchdb:latest)...
ERROR: manifest for hyperledger/fabric-couchdb:latest not found
解决办法
查了一下，貌似是没有配置Hyperledger Fabric Samples的工具库
问题二
按照Hyperledger Fabric Samples的教程，在执行curl -sSL https://goo.gl/Gci9ZX | bash时，卡死了，和可能是网络问题；
解决办法：
在浏览器里打开https://goo.gl/Gci9ZX，其代码如下
#!/bin/bash

export ARCH=$(echo "$(uname -s|tr '[:upper:]' '[:lower:]'|sed 's/mingw64_nt.*/windows/')-$(uname -m | sed 's/x86_64/amd64/g')" | awk '{print tolower($0)}')
#Set MARCH variable i.e ppc64le,s390x,x86_64,i386

dockerFabricPull() {

}

dockerFabricPull ${FABRIC_TAG}
echo "===> Pulling fabric ca Image"
dockerCaPull ${CA_TAG}
echo
echo "===> List out hyperledger docker images"
docker images | grep hyperledger*
将代码复制到fabric-samples/init.sh，然后运行
./init.sh
开始自动下载需要的docker image，网速不给力，这里需要较长时间，可以给Docker配置代理，配置代理教程
iMacdeiMac-2:fabric-samples imactwo$ ./init.sh

问题三
在npm install 时，因为使用了node版本管理器n，报错如下：
npm ERR! code MODULE_NOT_FOUND
npm ERR! Cannot find module 'internal/fs'
╭─────────────────────────────────────╮
│ │
│ Update available 5.0.0 → 5.4.1 │
│ Run npm i -g npm to update │
│ │
╰─────────────────────────────────────╯
npm ERR! A complete log of this run can be found in:
npm ERR! /Users/imactwo/.npm/_logs/2017-09-12T05_37_44_321Z-debug.log
解决办法
此时node版本为8.0.0，先用n将node版本改为6.2.2，再使用npm i -g npm安装最新版的npm
问题四
在https://hyperledger-fabric.readthedocs.io/en/latest/prereqs.html上有如下提示：
屏幕快照 2017-09-12 下午2.40.00.png
使用n安装node 6.9.5，因为网络问题，下载特别慢，查到这个博客，配置加速来提高下载速度
PROJECT_NAME="node" PROJECT_URL="https://npm.taobao.org/mirrors/node/" n project 6.9.5
