文件忽略了 PyCharm Pro IDE，这是 PYTHONPATH 的正确 sys.path？

我PyCharm IDE不会自动创建一个venv directory，所以我必须手动创建我自己的。我的venv directory出现被忽略了。这个是正常的。在评论部分找到了一个可能的解决方案。创建PyCharm Project Django并virtualenv安装时。我不必安装Django. 所以现在Python3需要清理。

更新：我已经有PyCharm IDE一段时间了，我想确定是sys.path：来自PyCharm IDE terminal：

>>> python3
>>> import sys
>>> print(sys.path)
    ['', '/usr/lib/python37.zip', '/usr/lib/python3.7', '/usr/lib/python3.7/lib-dynload', '/home/name/Projects/bye/venv/lib/python3.7/site-packages', '/home/name/Projects
/bye/venv/lib/python3.7/site-packages/setuptools-40.8.0-py3.7.egg', '/home/name/Projects/bye/venv/lib/python3.7/site-packages/pip-19.0.3-py3.7.egg']

尽管创建了目录，但我仍然得到这个结果：

 ImportError(
                "Couldn't import Django. Are you sure it's installed and "
                "available on your PYTHONPATH environment variable? Did you "
                "forget to activate a virtual environment?"

ImportError 由以下 Python 3 代码的第 6 行生成，不一定由代码生成，而是由第from django.core.management import4 行生成。

    def main():
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'Example.settings')
    try:
        from django.core.management import execute_from_command_line
    except ImportError as exc:
        raise ImportError(
            "Couldn't import Django. Are you sure it's installed and "
            "available on your PYTHONPATH environment variable? Did you "
            "forget to activate a virtual environment?"
        ) from exc
    execute_from_command_line(sys.argv)

    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'Example.settings')
