原来是机器上安装的Python-3有问题

 重新安装python3
1、解压安装包

#tar –zxvf Python-3.7.7.tgz

2、安装依赖

# yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel xz-devel gdbm-devel

3、编译源码

#cd Python-3.7.7

#./configure --prefix=/usr/local/python3

#make

#make install

如果没有报错就可以认为安装成功。

5、建立软链接

#ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3

#ln –s /usr/local/python3/bin/pip3.7 /usr/bin/pip3

6、验证

#python3

#pip3

卸载python3
      rpm -qa|grep python3|xargs rpm -ev --allmatches --nodeps       卸载pyhton3
      whereis python3 |xargs rm -frv           删除所有残余文件
      成功卸载！
      whereis   python       查看现有安装的python

pip 官网：https://pypi.org/project/pip/

你可以通过以下命令来判断是否已安装：

pip --version
如果你还未安装，则可以使用以下方法来安装：

$ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py   # 下载安装脚本
$ sudo python get-pip.py    # 运行安装脚本
注意：用哪个版本的 Python 运行安装脚本，pip 就被关联到哪个版本，如果是 Python3 则执行以下命令：

$ sudo python3 get-pip.py    # 运行安装脚本。

python -m pip uninstall pip

 yum -y install  python3

 yum -y install  python3-pip

pip install virtualenv -i https://mirrors.aliyun.com/pypi/simple/
