pycharm继续连接到调试器并等待连接

Question

pycharm继续连接到调试器并等待连接。 我使用python 2.7，环境变量包含'PYTHONUNBUFFERED = 1; PYCHARM_DEBUG = True'。
但是日志就像

/Users/suncong/.virtualenvs/lalala/bin/python2.7 /Applications/PyCharm.app/Contents/helpers/pydev/pydevd.py --multiproc --client 127.0.0.1 --port 53235 --file

我尝试删除名为.idea的文件夹，但是它不起作用。 重新启动计算机后，它可以正常工作，但过一会儿便恢复到上面的状态。
