error: externally-managed-environment (Python)

 Mac 系统 Brew 安装的最新的python 

第一次接触Python

• error: externally-managed-environment
• 在若依网站下载的项目，试着学习
• https://gitee.com/liqianglog/django-vue-admin/tree/v1.1.2
• 根据readMe安装初始化时出现了问题

• This environment is externally managed
  ╰─> To install Python packages system-wide, try brew install
  xyz, where xyz is the package you are trying to
  install.

  If you wish to install a non-brew-packaged Python package,
  create a virtual environment using python3 -m venv path/to/venv.
  Then use path/to/venv/bin/python and path/to/venv/bin/pip.
  
  If you wish to install a non-brew packaged Python application,
  it may be easiest to use pipx install xyz, which will manage a
  virtual environment for you. Make sure you have pipx installed.

• 创建并使用虚拟环境

  1. 创建虚拟环境

  python3 -m venv "虚拟环境的路径"

• 2. 激活虚拟环境

  source  
  "虚拟环境的路径"
  /bin/activate
  

• 3.在虚拟环境中安装

  pip install  xxxx

• 4. 退出虚拟环境

  deactivate

• 亲测没问题Python 环境是由外部系统（如 Homebrew）管理的。这种情况下，系统建议你不要直接使用 pip 安装包，以避免潜在的冲突和问题
