以下报错没有详细的信息，不知道代码具体哪里出了问题

Traceback (most recent call last):
  File "/home/charleswu/.virtualenvs/process/lib/python3.6/site-packages/gunicorn/arbiter.py", line 203, in run
    self.manage_workers()
  File "/home/charleswu/.virtualenvs/process/lib/python3.6/site-packages/gunicorn/arbiter.py", line 545, in manage_workers
    self.spawn_workers()
  File "/home/charleswu/.virtualenvs/process/lib/python3.6/site-packages/gunicorn/arbiter.py", line 617, in spawn_workers
    time.sleep(0.1 * random.random())
  File "/home/charleswu/.virtualenvs/process/lib/python3.6/site-packages/gunicorn/arbiter.py", line 245, in handle_chld
    self.reap_workers()
  File "/home/charleswu/.virtualenvs/process/lib/python3.6/site-packages/gunicorn/arbiter.py", line 525, in reap_workers
    raise HaltServer(reason, self.WORKER_BOOT_ERROR)
gunicorn.errors.HaltServer: <HaltServer 'Worker failed to boot.' 3>

只需要在输入gunicorn命令的时候在后边加上参数 –preload，便可看到详细的报错信息
加上参数后的报错信息如下：
