创建 venv 时出错，错误:命令 '-Im'、'ensurepip'、'--upgrade'、'--default-pip']' 返回非零退出状态 1

问题描述

当我尝试创建 venv 时，它会抛出此错误:

When I try to create venv it throws this error:

错误:命令 '['C:\Users\admin\env\Scripts\python.exe', '-Im', 'ensurepip', '--upgrade', '--default-pip']' 返回非零退出状态 1.

我很奇怪，因为我用python很久了，从来没有遇到过这样的问题.

It is strange for me because I'm using python for a long time and never had such a problem.

解决方案

1- 顶一下 doc 并尝试相应地修复您的全局 python 安装，不要忘记检查 Install launcher for all users 选项，成功安装后 py 启动器 将本地化在 C:Windows 文件夹下.

1- head over this doc and try to refix your global python installation accordingly, don't forget to check Install launcher for all users option, after successful installation the py launcher will be localed under C:Windows folder.

2- 使用隔离的虚拟环境，venv 内置模块比其他第三个工具更推荐，避免弄乱你的全局 python 文件夹.

2- use isolated vrtual environement, venv built-in module is recommended over other 3rd tools and just avoid to mess with your global python folder.
