python - 创建环境时如何读取和修复 pipenv 错误？

问题描述

我开始了一个新项目，想通过 pipenv 创建一个虚拟环境，就像我过去七次所做的那样。我是 pipenv 的初学者/新手，但设法让事情做我想做的事情，并且在我无法自己解决之前没有遇到任何重大问题。我真的很喜欢没有在我的系统上安装大量的依赖项，并且希望坚持使用虚拟环境。

要创建问题，我只需在一个新文件夹中生成一个新的锁定文件，无论是否事先有文件。已经生成的锁文件可以正常工作（没有尝试在旧项目中安装新的依赖项）。

终端

-> 工作区 pipenv 锁

Failed to create virtual environment.

我希望锁定文件，并且我正在为我的项目安装所需的依赖项的路上，但我却陷入了这个错误。我对一般系统管理知之甚少，这就是为什么我尽量避免在系统范围内安装依赖项/包。

我检查了名为：“OError: [Errno 26] Text file busy: '/...myvirtualenv/bin/python'”的线程，但没有让我更接近解决问题。

希望有人能够帮助我。

解决方案

我通过 python (python -run pipenv) 使用带有我创建的别名的 pipenv，而不是使用 bin 文件的路径 (~/usr/local/bin/pipenv)。更改别名以引用路径解决了该问题。
