Question

我正在尝试使用gunicorn启动烧瓶应用程序，但是我遇到了问题。

从命令行启动它时，可以通过以下命令正常工作：

/usr/local/bin/gunicorn --preload --certfile /etc/letsencrypt/live/server_name.net/fullchain.pem --keyfile /etc/letsencrypt/live/server_name.net/privkey.pem -w 17
-b 0.0.0.0:9090 wsgi:app

.sh脚本中的同一命令会引发错误：

    Traceback (most recent call last):
  File "/usr/local/bin/gunicorn", line 11, in <module>
    sys.exit(run())
  File "/usr/local/lib/python3.4/dist-packages/gunicorn/app/wsgiapp.py", line 61, in run
    WSGIApplication("%(prog)s [OPTIONS] [APP_MODULE]").run()
  File "/usr/local/lib/python3.4/dist-packages/gunicorn/app/base.py", line 221, in run
    super(Application, self).run()
  File "/usr/local/lib/python3.4/dist-packages/gunicorn/app/base.py", line 70, in run
    Arbiter(self).run()
  File "/usr/local/lib/python3.4/dist-packages/gunicorn/arbiter.py", line 58, in __init__
    self.setup(app)
  File "/usr/local/lib/python3.4/dist-packages/gunicorn/arbiter.py", line 118, in setup
    self.app.wsgi()
  File "/usr/local/lib/python3.4/dist-packages/gunicorn/app/base.py", line 65, in wsgi
    self.callable = self.load()
  File "/usr/local/lib/python3.4/dist-packages/gunicorn/app/wsgiapp.py", line 52, in load
    return self.load_wsgiapp()
  File "/usr/local/lib/python3.4/dist-packages/gunicorn/app/wsgiapp.py", line 41, in load_wsgiapp
    return util.import_app(self.app_uri)
  File "/usr/local/lib/python3.4/dist-packages/gunicorn/util.py", line 372, in import_app
    __import__(module)
ImportError: No module named '.0'

cli和.sh都以root用户身份运行。

同一脚本在另一台服务器上可以正常工作，所以我认为环境存在问题。

我尝试在脚本的开头添加以下几行，但没有成功：

$PYTHONPATH=/path/to/my/app

和

$PWD=/path/to/my/app

这是我正在使用的wsgi文件：

from api import app

if __name__ == "__main__":
    app.run()

知道可能是什么问题吗？

我终于能够解决这个问题。以下脚本似乎有效：

cd /path_to_app/
gunicorn --certfile=/etc/letsencrypt/live/server_name.net/fullchain.pem --keyfile=/etc/letsencrypt/live/server_name.net/privkey.pem -w 4 -b 0.0.0.0:9090 wsgi:app

使用.sh启动gunicorn时出现问题（没有名为“ .0”的模块）
