Pipenv 安装错误：命令“python setup.py egg_info”失败，错误代码为 1

Question

我最近开始使用 pipenv 并且在尝试安装软件包时时不时地收到以下错误：

$ pipenv lock --clear --verbose

pipenv.patched.notpip._internal.exceptions.InstallationError: Command "python setup.py egg_info" failed with error code 1 in

$ pipenv install 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'

错误的github页面没有帮助，谢谢

我认为这些可能是最新的 pipenv 中已修复的错误。您使用的是最新版本的 pipenv（以及 pip、setuptools 和 wheel）吗？

假设您使用--user 安装，您可以使用以下命令升级和/或检查：

$ pip install --user --upgrade --upgrade-strategy eager pipenv wheel
Requirement already up-to-date: pipenv in ./.local/lib/python3.6/site-packages (2018.11.26)
Requirement already up-to-date: wheel in ./.local/lib/python3.6/site-packages (0.32.3)
Requirement already up-to-date: setuptools>=36.2.1 in ./.local/lib/python3.6/site-packages (from pipenv) (40.6.3)
Requirement already up-to-date: virtualenv in ./.local/lib/python3.6/site-packages (from pipenv) (16.1.0)
Requirement already up-to-date: virtualenv-clone>=0.2.5 in ./.local/lib/python3.6/site-packages (from pipenv) (0.4.0)
Requirement already up-to-date: pip>=9.0.1 in ./.local/lib/python3.6/site-packages (from pipenv) (18.1)
Requirement already up-to-date: certifi in ./.local/lib/python3.6/site-packages (from pipenv) (2018.11.29)

注意：这应该在您的虚拟环境之外运行，而不是在它被激活时运行。
