怎么同时 安装python3和python2
早睡睡睡:
基本按照楼主的指引，全部装完了，最后一步查看pip2 -v的时候发现看不了，只能看pip3 -v的。[code=csharp]C:\Users\74606>pip2 -V
Fatal error in launcher: Unable to create process using '"D:\python\Python2\python.exe" "D:\python\Python2\Scripts\pip2.exe" -V'
[/code]
然后我去Python2的pip[code=csharp]C:\Users\74606>python2 -m pip install --upgrade pip --force-reinstall
Collecting pip
Exception:
