我在学习第12-9章 Tornado部署的时候，执行 python TornadoServer.py —port=6001的时候会报错如下：

这是celery_app.py的代码：

import os
from celery import Celery

# set the default Django settings module for the 'celery' program.
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings.local")

app = Celery("zanhu")

# Using a string here means the worker doesn't have to serialize
# the configuration object to child processes.
# - namespace='CELERY' means all celery-related configuration keys
#   should have a `CELERY_` prefix.
app.config_from_object("django.conf:settings", namespace="CELERY")

# Load task modules from all registered Django app configs.
app.autodiscover_tasks()

这是TornadoServer.py的代码：

import os
import sys
from tornado.options import options, define
from django.core.wsgi import get_wsgi_application
import tornado.httpserver
import tornado.ioloop
import tornado.web
import tornado.wsgi

# Django Application加入查找路径中
app_path = os.path.abspath(os.path.join(os.path.dirname(os.path.abspath(__file__)), os.pardir))
sys.path.append(os.path.join(app_path, 'zanhu'))  # ../zanhu/zanhu
define("port", default=6000, type=int, help="run on the given port")


def main():
    tornado.options.parse_command_line()
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings.production")
    wsgi_app = tornado.wsgi.WSGIContainer(get_wsgi_application())
    http_server = tornado.httpserver.HTTPServer(wsgi_app, xheaders=True)  # xheaders=True是啥意思？
    http_server.listen(options.port)
    tornado.ioloop.IOLoop.instance().start()


if __name__ == "__main__":
    main()

启动tornado的时候好像不会从pipenv创建的虚拟环境目录去寻找module.当我把全局里的uninstall tornado 之后，只有在项目的虚拟环境里install tornado，连tornado也找不到。
所有执行文件里的module都会找不到。难道所有项目依赖都要全局install一遍？
ps:项目本身是能正常启动的
