错误提示：

在当前目录下创建了个python虚拟环境，新建在venv-python38-data目录下

D:\Python>python -m venv venv-python38-data

D:\Python>ls

将目录改名成了vPython38-data，这时报错Fatal error in launcher: Unable to create process using ：

D:\Python\vPython38-data>
D:\Python\vPython38-data>
D:\Python\vPython38-data>cd Scripts

D:\Python\vPython38-data\Scripts>pip install six
Fatal error in launcher: Unable to create process using '"d:\python\venv-python38-data\scripts\python.exe"  "D:\Python\vPython38-data\Scripts\pip.exe" install six'

D:\Python\vPython38-data\Scripts>

错误原因：

1、这时试图运行pip命令，提示还是在原来的目录下找python，所以运行出错：

解决方法：

1、重新按照新文件夹名安装一次虚拟环境后，pip安装包ok：

D:\Python>python -m venv vPython38-data

D:\Python>cd vPython38-data\Scripts

D:\Python\vPython38-data\Scripts>pip install six
