Ubuntu18.04 搭建虚拟环境

# 安装虚拟环境流程
sudo apt install virtualenv
sudo apt install virtualenvwrapper
sudo find / -name virtualenvwrapper.sh
mkdir ~/.virtualenvs    #创建虚拟环境

# 在~/.bashrc 中添加以下内容
$ vim ~/.bashrc   # 进入~/.bashrc
export WORKON_HOME=HOME/.vritualenvs
source /usr/share/virtualenvwrapper/virtualenvwrapper.sh
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3

# 填写后刷新配置
$ source ~/.bashrc

sudo apt-get install python3-pip
sudo pip3 install virtualenv virtualenvwrapper

修改KaTeX parse error: Undefined control sequence: which at position 10: (command ̲w̲h̲i̲c̲h̲ ̲python) ------…(command which python3)

# Locate the global Python where virtualenvwrapper is installed.
if [ "$VIRTUALENVWRAPPER_PYTHON" = "" ]
then
    VIRTUALENVWRAPPER_PYTHON="$(command which python3)"
fi

修改后刷新

source /usr/share/virtualenvwrapper/virtualenvwrapper.sh

mkvirtualenv zs -p /usr/bin/python3
