# 配置仓库
sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository ppa:deadsnakes/ppa

# 这里是安装 python3.7.5 之后, 需要安装三方库和包的情况, 解决安装 venv 不成功的问题:
sudo apt install python3.7 python3-venv python3.7-venv
python3.7 -m venv my_env_name

# 如果虚拟环境中安装三方库还会报其他错, 如:
# 1.报错: error: invalid command 'bdist_wheel'
# 解决:
pip install wheel

另外一个报错的解决:
