我运行了以下命令：

  • python --version => 2.7.10

  • pip --version ，显示：

pip 18.1 from /Library/Python/2.7/site-packages/pip-18.1-py2.7.egg/pip (python 2.7)
  • pip install --user pipenv

软件包看起来安装得很好 - 我可以在我的程序中引用它们，但在锁定步骤中显然有问题 .

正如建议here我试着运行 pipenv lock --clear 没有运气 .

有什么建议？我能做些什么来避免这个错误？

python python-2.7 pipenv
