manage.py runserver在VPS上不执行任何操作

Question

当我在Ubuntu 16.04 VPS机器上运行python3 manage.py runserver时，它对我的项目没有任何作用，但它在我的计算机上运行。

我尝试运行python3 -v manage.py runserver，并看到它在执行以下命令时停止：

# code object from '/usr/lib/python3.5/site-packages/OpenSSL/__pycache__/SSL.cpython-35.pyc'
import 'OpenSSL.SSL' # <_frozen_importlib_external.SourceFileLoader object at 0x2b1d1d937630>
# /usr/lib/python3.5/site-packages/OpenSSL/__pycache__/version.cpython-35.pyc matches /usr/lib/python3.5/site-packages/OpenSSL/version.py
# code object from '/usr/lib/python3.5/site-packages/OpenSSL/__pycache__/version.cpython-35.pyc'
import 'OpenSSL.version' # <_frozen_importlib_external.SourceFileLoader object at 0x2b1d1e6a5c50>
import 'OpenSSL' # <_frozen_importlib_external.SourceFileLoader object at 0x2b1d1d923da0>

在最后一行之后，它开始什么都不做

my settings.py文件：

我试图创建另一个项目，但它运行得很完美，所以问题出在我的项目中，你能帮我吗？(

UPD-

现在，当我尝试做pip3 list时，它也依赖于导入密码模块

import 'cryptography.hazmat.primitives.kdf.scrypt' # <_frozen_importlib_external.SourceFileLoader object at 0x2ac73f3a9588>
