使用Pipenv创建虚拟环境时遭遇FileNotFoundError报错

Pipenv无法正常工作 #

在WSL shell中使用pipenv时遇到问题，之前一直正常使用，今天突然无法运行。已尝试卸载并重新安装pipenv，但问题仍未解决。

执行的命令：

pipenv install django

错误输出：

FileNotFoundError: [Errno 2] 没有那个文件或目录: '/home/edzy/.local/share/virtualenvs/To-do-list-JHrSlGzr/bin/python'

解决方案 #

错误核心是虚拟环境创建后找不到python可执行文件，按以下步骤修复：

• 清理损坏的虚拟环境
  删除当前项目的虚拟环境目录，以及项目下的Pipfile文件：

  rm -rf /home/edzy/.local/share/virtualenvs/To-do-list-JHrSlGzr
  cd /mnt/d/Projects/To-do-list && rm -f Pipfile Pipfile.lock
  

• 重新创建虚拟环境
  进入项目目录，明确指定Python路径创建环境并安装依赖：

  cd /mnt/d/Projects/To-do-list
  pipenv --python /usr/bin/python3.10 install django
  

• 检查目录权限
  如果问题依旧，确认项目目录的权限归属：

  ls -ld /mnt/d/Projects/To-do-list
  

  若当前用户无读写权限，执行以下命令修改：

  sudo chown -R edzy:edzy /mnt/d/Projects/To-do-list
  

• 消除版本警告（可选）
  针对pkg_resources的版本警告，升级setuptools即可解决：

  pip install --upgrade setuptools
