各位大佬好，我最近碰到个棘手的问题，折腾好久没解决，想请教下大家：

我用Python搭配venv快一年了一直好好的，结果现在突然没法创建虚拟环境了！

具体报错情况 #

• 运行 python -m venv .（这个命令指向Python3.13），报错：

  Error: Command '['/Users/sejaques/bin/python3.13', '-m', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.
  

• 换成指向Python3.14的 python3 -m venv .，同样报错，只是路径里的版本变成了3.14：

  Error: Command '['/Users/sejaques/bin/python3.14', '-m', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.
  

我自己排查尝试的过程 #

• 版本不匹配怀疑：我发现Homebrew里装了Python3.14，但python -V返回3.13，python3 -V返回3.14，本来以为是版本不一致导致的，查了相关方法想统一版本，结果发现很多方案反而推荐用虚拟环境——这就陷入死循环了😂
• venv未安装怀疑：看有些问题说这种报错是venv没装，但我搞不懂怎么装啊：正常Python不是自带venv吗？而且Homebrew里搜不到venv的包，装包又得要么在虚拟环境里要么用Homebrew，现在虚拟环境都建不了...
• 尝试单独运行ensurepip：根据评论建议，我单独跑了python3 -m ensurepip --upgrade --default-pip（python3.13直接提示command not found），结果报了一大段回溯错误，如下：

现在实在不知道该从哪下手了，有没有大佬碰到过类似的情况，或者能给点排查方向的？万分感谢！
