如何修复 pipelinev 中的 VersionConflict 锁定失败？

这是我的调试笔记。仍然不确定哪个包导致了问题，但这似乎确实解决了问题。pipenv install首次使用 pipelinev version运行时出现的错误2020.8.13。Traceback (most recent call last):  File "/usr/local/bin/pipenv", line 8, in <module>    sys.exit(cli())  File "/usr/local/lib/python3.6/site-packages/pipenv/vendor/click/core.py", line 829, in __call__    return self.main(*args, **kwargs)  File "/usr/local/lib/python3.6/site-packages/pipenv/vendor/click/core.py", line 782, in main    rv = self.invoke(ctx)  File "/usr/local/lib/python3.6/site-packages/pipenv/vendor/click/core.py", line 1259, in invoke    return _process_result(sub_ctx.command.invoke(sub_ctx))  File "/usr/local/lib/python3.6/site-packages/pipenv/vendor/click/core.py", line 1066, in invoke    return ctx.invoke(self.callback, **ctx.params)  File "/usr/local/lib/python3.6/site-packages/pipenv/vendor/click/core.py", line 610, in invoke    return callback(*args, **kwargs)  File "/usr/local/lib/python3.6/site-packages/pipenv/vendor/click/decorators.py", line 73, in new_func    return ctx.invoke(f, obj, *args, **kwargs)  File "/usr/local/lib/python3.6/site-packages/pipenv/vendor/click/core.py", line 610, in invoke    return callback(*args, **kwargs)  File "/usr/local/lib/python3.6/site-packages/pipenv/vendor/click/decorators.py", line 21, in new_func    return f(get_current_context(), *args, **kwargs)  File "/usr/local/lib/python3.6/site-packages/pipenv/cli/command.py", line 252, in install    site_packages=state.site_packages  File "/usr/local/lib/python3.6/site-packages/pipenv/core.py", line 1928, in do_install    site_packages=site_packages,  File "/usr/local/lib/python3.6/site-packages/pipenv/core.py", line 580, in ensure_project    pypi_mirror=pypi_mirror,  File "/usr/local/lib/python3.6/site-packages/pipenv/core.py", line 512, in ensure_virtualenv    python=python, site_packages=site_packages, pypi_mirror=pypi_mirror  File "/usr/local/lib/python3.6/site-packages/pipenv/core.py", line 999, in do_create_virtualenv    project._environment.add_dist("pipenv")  File "/usr/local/lib/python3.6/site-packages/pipenv/environment.py", line 135, in add_dist    self.extend_dists(dist)  File "/usr/local/lib/python3.6/site-packages/pipenv/environment.py", line 127, in extend_dists    extras = self.resolve_dist(dist, self.base_working_set)  File "/usr/local/lib/python3.6/site-packages/pipenv/environment.py", line 122, in resolve_dist    deps |= cls.resolve_dist(dist, working_set)  File "/usr/local/lib/python3.6/site-packages/pipenv/environment.py", line 121, in resolve_dist    dist = working_set.find(req)  File "/usr/local/lib/python3.6/site-packages/pkg_resources/__init__.py", line 642, in find    raise VersionConflict(dist, req)pkg_resources.VersionConflict: (importlib-metadata 2.0.0 (/usr/local/lib/python3.6/site-packages), Requirement.parse('importlib-metadata<2,>=0.12; python_version < "3.8"'))如果你运行pip install -U pipenv它似乎会更改importlib-metadata版本：Installing collected packages: importlib-metadata  Attempting uninstall: importlib-metadata    Found existing installation: importlib-metadata 2.0.0    Uninstalling importlib-metadata-2.0.0:      Successfully uninstalled importlib-metadata-2.0.0Successfully installed importlib-metadata-1.7.0现在如果你运行pipenv install -d --skip-lock它就会完成。看起来图书馆需要一个版本>= importlib-metadata 2.0。当我固定以下依赖项时，它在运行时一开始不起作用pipenv lock，但是，如果我删除了锁定文件（rm Pipenv.lock），那么当我pipenv lock再次运行时它就起作用了。virtualenv = "==20.0.31"importlib-metadata = "==1.7.0"
