Ubuntu20.04 安装Python3 Virtualenv 虚拟环境

# Step 1: Update your repositories
sudo apt-get update

# Step 2: Install pip for Python 3
sudo apt-get install build-essential libssl-dev libffi-dev python-dev
sudo apt install python3-pip

# Step 3: Use pip to install virtualenv
sudo pip3 install virtualenv 

# Step 4: Launch your Python 3 virtual environment, here the name of my virtual environment will be env3
virtualenv -p python3 env3

# Step 5: Activate your new Python 3 environment. There are two ways to do this
. env3/bin/activate # or source env3/bin/activate which does exactly the same thing

# you can make sure you are now working with Python 3
python -- version
# this command will show you what is going on: the python executable you are using is now located inside your virtualenv repository
which python 

# Step 6: code your stuff

# Step 7: done? leave the virtual environment
deactivate

也可以使用python3自带的虚拟环境 (感觉挺好用)

sudo apt-get install python3-venv

cd 目录
#创建虚拟环境
python3 -m venv venv

#启动虚拟环境
source venv/bin/activate

#关闭虚拟环境
activate


python3 -m venv 虚拟环境的名字
