缺少 concurrent模块，可单独运行python -c 'from concurrent import futures'没有错误
安装 pip install futures 也提示已经安装了
可能是项目存在了concurrent.py ,查找 find / -name concurrent.py ,果然
/usr/local/lib/python2.7/site-packages/tornado-4.5.2-py2.7-linux-x86_64.egg/tornado/concurrent.py
看来是tornado版本的问题，卸载

pip uninstall tornado

重新安装低版本

pip install tornado==2.4.1

查看版本

python -V
python -c "import tornado; print(tornado.version)"

启动悲剧了，起不来，重新安装gateone 发现请求tornado>4.0 并且自动搜索安装了最新版本！太坑爹了吧。看github上gateone好久都没啥更新了，对老版本的兼容性不好。
该问题暂时未解决。。。issue
