我最近转移到使用pipenv，并且每次尝试安装软件包时都会出现以下错误：
$ pipenv锁定-清除-详细
pipenv.patched.notpip._internal.exceptions.InstallationError: Command "python setup.py egg_info" failed with error code 1 in
$ pipenv安装social-auth-core
line 704, in from_line
line, extras = _strip_extras(line)
TypeError: 'module' object is not callable
$ python setup.py egg_info
(k, v) for k, v in attrs.items()
File "/home/user/.local/share/virtualenvs/django-app-VE-name/lib/python3.6/site-packages/setuptools/dist.py", line 367, in __init__
for ep in pkg_resources.iter_entry_points('distutils.setup_keywords'):
AttributeError: module 'pkg_resources' has no attribute 'iter_entry_points'
该错误的github页面没有帮助，谢谢
