使用 Python 开始使用 Heroku 时遇到问题

Question

我正在使用 Heroku 和 Python 为我的网站设置后端。通过这样做，我正在关注 Heroku 的设置。但是我的问题出现在这一步here。

当我尝试运行时：python3 manage.py collectstatic

我得到以下信息：

    Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/usr/local/lib/python3.7/site-packages/django/core/management/__init__.py", line 381, in execute_from_command_line
    utility.execute()
  File "/usr/local/lib/python3.7/site-packages/django/core/management/__init__.py", line 375, in execute
    self.fetch_command(subcommand).run_from_argv(self.argv)

    self.execute(*args, **cmd_options)
  File "/usr/local/lib/python3.7/site-packages/django/core/management/base.py", line 353, in execute
    output = self.handle(*args, **options)
  File "/usr/local/lib/python3.7/site-packages/django/contrib/staticfiles/management/commands/collectstatic.py", line 188, in handle
    collected = self.collect()
  File "/usr/local/lib/python3.7/site-packages/django/contrib/staticfiles/management/commands/collectstatic.py", line 105, in collect
    for path, storage in finder.list(self.ignore_patterns):
  File "/usr/local/lib/python3.7/site-packages/django/contrib/staticfiles/finders.py", line 125, in list
    for path in utils.get_files(storage, ignore_patterns):
  File "/usr/local/lib/python3.7/site-packages/django/contrib/staticfiles/utils.py", line 23, in get_files
    directories, files = storage.listdir(location)
  File "/usr/local/lib/python3.7/site-packages/django/core/files/storage.py", line 313, in listdir
    for entry in os.listdir(path):
FileNotFoundError: [Errno 2] No such file or directory: '/Users/aaronmiller/Development/python-getting-started/static'

我已经按照说明一步一步地尝试过，但总是卡在上面的部分。与：

如果我能提供任何其他信息，请告诉我，我会提供的。

更新

我停止在 python 2 上尝试这个，然后我取出下面添加到 settings.py 的代码

# Extra places for collectstatic to find static files.
STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),
)

django-heroku 包需要 Python 3，请参阅 README 文件：https://github.com/heroku/django-heroku/blob/master/README.rst

编辑：您的系统上似乎有 python3 可用，因此请尝试运行以下命令：

python3 manage.py collectstatic

您需要为 python3 环境重新安装为 python2 安装的所有依赖项（可能使用pip）。你有pip3 可用吗？
