SDIST在将软件包上传到PYPI时显示错误

Question

我正在构建一个python模块，并且正在关注此教程。 但是，当我运行python setup.py sdist时，我得到：

running sdist
running check
warning: sdist: manifest template 'MANIFEST.in' does not exist (using default file list)

error: package directory 'packagename' does not exist

这是我的目录结构：

packagename  
-setup.py  
-setup.cfg  
-LICENSE  
-README  
-__init__.py   
-(All other files)

setup.py文件（我替换了诸如包装名称，作者，带有占位符的URL之类的内容。）：

from distutils.core import setup
setup(
  name = 'packagename',
  packages = ['packagename'],
  version = '0.1.1',
  license='MIT',
  description = 'description',
  author = 'authorname',
  author_email = '[email protected]',
  url = 'url',
  download_url = 'url',
  keywords = ['GUI', 'Python', 'Tkinter', 'Simple'],
  classifiers=[
    'Development Status :: 4 - Beta',      # Choose either "3 - Alpha", "4 - Beta" or "5 - Production/Stable" as the current state of your package
    'Intended Audience :: Developers',
    'Topic :: Software Development :: Build Tools',
    'License :: OSI Approved :: MIT License',
    'Programming Language :: Python :: 3.6',
    'Programming Language :: Python :: 3.7',
    'Programming Language :: Python :: 3.8',
    'Programming Language :: Python :: 3.9',
  ],
)

我必须按照@PHD在评论部分的第三评论中建议将设置文件移至主包上方。
