python 创建虚拟环境遇到的问题

mk Virtual env django_env -p python3会遇到一些问题，

1.首先需要安装1.升级python包管理工具pip

pip install --upgrade pip

备注：当你想升级一个包的时候`pip install --upgrade包名`

2.python虚拟环境安装

sudo apt-get install python- Virtual env

sudo easy_install  Virtual envwrapper

命令输入：mk Virtual env

报错：bash: mk Virtual env:未找到命令，需要执行以下环境变量设置。

1.创建目录用来存放虚拟环境

    mkdir $HOME/. Virtual envs

2.在~/.bashrc中添加行：

    export WORKON_HOME=$HOME/. Virtual envs

    source /usr/local/bin/ Virtual envwrapper.sh

3.运行:

source ~/.bashrc

报错

/usr/bin/python: No module named  Virtual envwrapper

 Virtual envwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module  Virtual envwrapper.hook_loader,

check that  Virtual envwrapper has been installed for

 Virtual ENVWRAPPER_PYTHON=/usr/bin/python and that PATH is

set properly.

解决办法：sudo vim ~/.bashrc

export WORKON_HOME=$HOME/. Virtual envs

export  Virtual ENVWRAPPER_PYTHON=/usr/bin/python3

source /usr/local/bin/ Virtual envwrapper.sh

4.    mk Virtual env django_env -p python3

报错

PermissionError: [Errno 13] Permission denied: ‘/home/shizhifeng/. Virtual envs/django_env‘

解决：使用虚拟环境 Virtual env创建虚拟环境出现PermissionError: [Errno 13] Permission denied:

原因：虚拟环境安装的目录所属用户非当前用户

解决办法：将目录及其文件的所有者改为当前用户

当前用户查看命令：whoami

解决命令：sudo chown -R当前用户待更改用户的目录/    实例：sudo chown -R shizhifeng /home/shizhifeng/. Virtual envs/
