BUG描述
[ERROR] BCOS-RPC port 8545 is not avaliable. Are there any other blockchain is running?

重现方式

  1. 停止本地运行的FISCO BCOS，cd fisco/nodes/127.0.0.1 bash stop_all.sh
  2. 查看端口，netstat -lntpu，已经没有8545

  1. 运行wecross安装脚本，bash clear.sh bash build.sh
  2. 报错：[ERROR] BCOS-RPC port 8545 is not avaliable. Are there any other blockchain is running?

环境

已知bug，判断端口是否存在时用了netstat + grep的方式，导致8545如果是端口的子串也会判断存在。如存在18545端口，也会判断8545已存在。

修复方法：判断是否是此问题，若是，可编辑build.sh文件，将check_port_avaliable 8545注释掉

此问题将在v1.0.0中修复 👍
