Python代码编写 米家设备接入homekit（mac端）

1.打开mac

2.打开终端item

3.查看版本

$ conda -V

4.安装pip，

$ conda install pip=20.2.4

出现状况，报错

[Errno 13] Permission denied: '/Users/zhouli/opt/anaconda3/lib/python3.7/site-packages/attr/__init__.py'

有可能是conda的版本号不一致引起的问题 所以更新版本号： 试试下面的代码

$ conda update -n base -c defaults conda

依然报错，试试下面的代码

$ sudo conda update -n base -c defaults conda

需要输入密码，输入密码

查看环境

$ conda info --env

创建环境，环境命名为HomeAssistant

$ conda create -n HomeAssistant

激活环境

$ conda activate HomeAssistant

安装homeassistant

$ sudo pip3 install homeassistant

出现警告

WARNING: Running pip as the 'root' user can result in broken permissions and conflicting behaviour with the system package manager. It is recommended to use a virtual environment instead: https://pip.pypa.io/warnings/venv

重新安装python 3 Python Releases for macOS | Python.org  下载Python3.7.9

在重新安装环境

Home Assistant 官方推荐使用 Python 虚拟环境安装 Home Assistant 以避免影响生产环境。

创建虚拟环境：

 python3 -m venv homeassistant

 打开虚拟环境： 

cd homeassistant

激活虚拟环境

source bin/activate

安装 Home Assistant： 

python3 -m pip install --upgrade homeassistant

依然出现

WARNING: You are using pip version 20.1.1; however, version 22.0.4 is available.
You should consider upgrading via the '/Users/zhouli/homeassistant/bin/python3 -m pip install --upgrade pip' command. 

尝试启动

hass --open-ui

出现 

ImportError: cannot import name 'contextfilter' from 'jinja2' (/Users/zhouli/homeassistant/lib/python3.7/site-packages/jinja2/__init__.py) 

问题在哪呢？
