Heroku 迁移：ModuleNotFoundError（怀疑静态问题）

Question

在尝试部署应用程序时，使用以下命令：heroku run python manage.py migrate错误Traceback (most recent call last):  File "manage.py", line 15, in <module>    execute_from_command_line(sys.argv)  File "/app/.heroku/python/lib/python3.6/site-packages/django/core/management/__init__.py", line 381, in execute_from_command_line    utility.execute()  File "/app/.heroku/python/lib/python3.6/site-packages/django/core/management/__init__.py", line 375, in execute    self.fetch_command(subcommand).run_from_argv(self.argv)  File "/app/.heroku/python/lib/python3.6/site-packages/django/core/management/__init__.py", line 224, in fetch_command    klass = load_command_class(app_name, subcommand)  File "/app/.heroku/python/lib/python3.6/site-packages/django/core/management/__init__.py", line 36, in load_command_class    module = import_module('%s.management.commands.%s' % (app_name, name))  File "/app/.heroku/python/lib/python3.6/importlib/__init__.py", line 126, in import_module    return _bootstrap._gcd_import(name[level:], package, level)  File "<frozen importlib._bootstrap>", line 994, in _gcd_import  File "<frozen importlib._bootstrap>", line 971, in _find_and_load  File "<frozen importlib._bootstrap>", line 955, in _find_and_load_unlocked  File "<frozen importlib._bootstrap>", line 665, in _load_unlocked  File "<frozen importlib._bootstrap_external>", line 678, in exec_module  File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed我怀疑这个问题是由我如何部署static. 特别是因为命令：python manage.py collectstatic返回以下错误：FileNotFoundError: [Errno 2] No such file or directory at: '/mnt/project/static/'。虽然，这可能是一个无关的问题。

正如@Selcuk 所说，问题是被Pipfile忽略的requirements.txt.

从基于requirements.txtto 的依赖项转换所需的步骤pipenv是：

$ pip install pipenv

$ pipenv install -r requirements.txt

$ pipenv lock
