celery错误：Monkey-patching not on the main thread（与gevent的pool不兼容）

/Users/wangpingyang/.pyenv/versions/3.7.2/lib/python3.7/site-packages/httprunner/__init__.py:5: MonkeyPatchWarning: Monkey-patching outside the main native thread. Some APIs will not be available. Expect a KeyError to be printed at shutdown.
  import gevent.monkey;gevent.monkey.patch_all()
/Users/wangpingyang/.pyenv/versions/3.7.2/lib/python3.7/site-packages/httprunner/__init__.py:5: MonkeyPatchWarning: Monkey-patching not on the main thread; threading.main_thread().join() will hang from a greenlet
  import gevent.monkey;gevent.monkey.patch_all()
/Users/wangpingyang/.pyenv/versions/3.7.2/lib/python3.7/site-packages/httprunner/__init__.py:5: MonkeyPatchWarning: Monkey-patching ssl after ssl has already been imported may lead to errors, including RecursionError on Python 3.6. It may also silently lead to incorrect behaviour on Python 3.7. Please monkey-patch earlier. See https://github.com/gevent/gevent/issues/1016. Modules that had direct imports (NOT patched): ['urllib3.contrib.pyopenssl (/Users/wangpingyang/.pyenv/versions/3.7.2/lib/python3.7/site-packages/urllib3/contrib/pyopenssl.py)']. 
  import gevent.monkey;gevent.monkey.patch_all()

方法一
import gevent.monkey;gevent.monkey.patch_all(thread=False)

方法二
<pythonpath>/Users/wangpingyang/.pyenv/versions/3.7.2/lib/python3.7/site-packages</pythonpath>

方法三

方法四
直接将Python版本更换为3.6版本

注意:我是在celery中调用多协程的任务，最后错误消失，但没有办法运行任务，改为多线程后，可以运行了，本人用了线程池ThreadPoolExecutor替代了gevent的pool
