三，解决
1. 寻找pip位置
# find / -name pip-*
root@localhost Init_auto]# find / -name pip-*
/home/Vitis/2019.2/cardano/tps/lnx64/target/chessdir/python-2.7.13/lib/python2.7/ensurepip/_bundled/pip-9.0.1-py2.py3-none-any.whl
2.创建虚拟环境
python3 -m venv tutorial-env
1.正常
不显示回显
[root@localhost ~]#
[root@localhost ~]# python3 -m venv tutorial-env
[root@localhost ~]#
3. 激活
[root@localhost ~]#
[root@localhost ~]# source tutorial-env/bin/activate
(tutorial-env) [root@localhost ~]#
(tutorial-env) [root@localhost ~]#
4.再次更新
pip install --upgrade pip
(tutorial-env) [root@localhost ~]# pip install --upgrade pip
