python - 如何修复pipenv中的锁定失败？

标签 python django docker-compose pipenv pipenv-install

我正在使用 pipenv在码头容器内。我尝试安装一个包，发现安装成功(被添加到 Pipfile 中)，但锁定一直失败。一切都很好，直到昨天。这是错误:

删除后 Pipfile.lock并尝试安装一个软件包，我得到:

最佳答案

这是我的调试笔记。仍然不确定是哪个软件包导致了问题，但这似乎确实可以解决问题。
第一次运行时遇到的错误 pipenv install使用 pipenv 版本 2020.8.13 .

如果您运行 pip install -U pipenv它似乎改变了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-2.0.0
Successfully installed importlib-metadata-1.7.0
现在，如果您运行 pipenv install -d --skip-lock它会完成。似乎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 pipenv lock 时起初不起作用，但是，如果我删除了锁定文件( rm Pipenv.lock )，那么当我运行 pipenv lock 时它就起作用了再次。
virtualenv = "==20.0.31"
importlib-metadata = "==1.7.0"
