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
