Home assistant python version

K210.ORG

Если вы пользуетесь Home Assistant, то после очередного обновления могли заметить на появившееся уведомление о том, что «Support for the running Python version 3.7.3 is deprecated and will be removed in the first release after December 7, 2020. Please upgrade Python to 3.8.0 or higher».

В стандартных системных репозиториях обычно содержатся стабильные и надежные версии пакетов, а не самые свежие и актуальные. И по состоянию на середину января 2021 года Python в репозиториях Debian и Ubuntu так и не спешат обновлять до версии 3.8.x.

Поэтому единственный вариант убрать назойливое уведомление и избавить себя от возможных проблем с совместимостью грядущих обновлений Home Assistant — это установить новую версию Python вручную, предварительно собрав ее из исходников.

Исходные данные

В этой статье я буду исходить из того, что:

• У вас уже установлен Home Assistant
• Он установлен в виртуальное окружение Python
• Используется операционнная система на базе Debian или Ubuntu

Если вы пользуетесь Docker-контейнерами или дистрибутивом Hass.io, то обновлять пакеты вручную вам не придется.

Обновление Python

Процесс обновления описан на примере актуальной на момент написания статьи версии Python 3.9.1. На странице загрузок Python всегда можно посмотреть номер свежего релиза и заменить ссылки на скачивание и распаковку архива в приведенных ниже командах.

Для начала остановим Home Assistant:

sudo systemctl stop home-assistant@homeassistant.service

Установим нужные для сборки из исходников пакеты:

sudo apt-get install build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev libxslt-dev libxml2-dev libjpeg-dev zlib1g-dev

Скачаем и распакуем архив с Python 3.9.1:

wget https://www.python.org/ftp/python/3.9.1/Python-3.9.1.tgz tar xzvf Python-3.9.1.tgz cd Python-3.9.1

Соберем его из исходников и запустим установку:

./configure --enable-optimizations make -j 4 sudo make install

Процесс сборки занимает около 12 минут на Raspberry Pi 4, поэтому придется запастись терпением.

После завершения установки можно проверить, что Python действительно обновился путем выполнения двух команд:

python3 --version pip3 --version

И если в консоли появится такие ответы, то процесс обновления прошел успешно:

Теперь обновим менеджер пакетов pip:

sudo /srv/homeassistant/bin/python3.9 -m pip install --upgrade pip sudo python3.9 -m pip install --upgrade pip

В случае если после обновления Python при запуске Home Assistant появится ошибка с доступностью библиотеки libffi.so.7 можно создать симлинк с libffi.so.7 на нее:

sudo ln -s /usr/lib/arm-linux-gnueabihf/libffi.so.6 /usr/lib/arm-linux-gnueabihf/libffi.so.7

Если симлинк не создается, то значит в вашей системе libffi.so.6 находится по другому пути. Найдите корректный путь через поиск по названиям файлов:

find /usr/lib -name "libffi.so*"

Переустановка Home Assistant

Теперь переустановим Home Assistant. Для этого сохраним в файл список используемых им пакетов Python:

cd /home/homeassistant/ sudo -u homeassistant -H -s source /srv/homeassistant/bin/activate pip3 freeze –local > requirements.txt deactivate exit

Удалим директорию с установленным Home Assistant и создадим ее заново:

sudo rm -r /srv/homeassistant sudo mkdir /srv/homeassistant sudo chown homeassistant:homeassistant /srv/homeassistant

Запустим процесс установки по сохраненному ранее списку пакетов:

sudo -u homeassistant -H -s cd /srv/homeassistant python3.9 -m venv . source /srv/homeassistant/bin/activate pip3 install wheel pip3 install -r /home/homeassistant/requirements.txt

И, наконец, перезапустим сервис Home Assistant:

sudo systemctl restart home-assistant@homeassistant

На этом процесс обновления завершен окончательно, и после перезапуска из панели уведомлений должно исчезнуть сообщение о неподдерживаемой версии Python.

Upgrading Your Home Assistant Core Python Virtual Environment

Since Python 3.9 is available, Home Assistant announced they were going no longer support Python versions lower than 3.8. This happens from time to time. If you run Home Assistant Core in a Python virtual environment, then you need to take action to maintain compatibility. I always forget these steps, so I decided to write an article I could always refer to.

Step 1: Install new version of Python

The first step is to install the new version of Python. How you do this will depend on what OS you are running. Many are woefully behind in their default Python versions. I run Ubuntu, and all my commands will be with Ubuntu in mind, but are easily adaptable to other distros. You check your version of Python by running the following commands:

python --version python3 --version

You’ll probably be running an older version of Python than you want. You can check your repos to see if there is an up to date version. If so, you can install it directly from the repos. Otherwise, Python is pretty easy to compile and install from source. If you wanted to install Python 3.8.5 you would do the following:

wget https://www.python.org/ftp/python/3.8.5/Python-3.8.5.tgz tar -xzf Python-3.8.5 cd Python-3.8.5 ./configure make -j 4 sudo make install

Depending on the speed of your system, this could take a little time, but should be straight forward.

Step 2: Backup your current Python packages

I don’t know if this step is strictly necessary to upgrading your Python virtual environment, but it is certainly prudent, especially if you made some changes and customization to Home Assistant that involved Python packages (like custom components). Assuming your Home Assistant config is in /home/homeassistant/.homeassistant and your Python virtual environment is in /srv/homeassistant:

cd /home/homeassistant/.homeassistant sudo -u homeassistant -H -s source /srv/homeassistant/bin/activate pip3 freeze –local > requirements.txt

This will put a listing of all your python packages in the file requirements.txt. You might want to take a peek at the file to make sure it looks right.

Step 3: Remove old Python virtual environment and create a new one

The first time I did this it was the scariest part. Instead of deleting the old python virtual environment, I recommend moving/renaming it, just in case. I recommend you stop Home Assistant at this point as well, although I don’t know that it is required:

sudo systemctl stop [email protected] cd /srv/ sudo mv homeassistant homeassistantold sudo mkdir homeassistant sudo chown homeassistant:homeassistant homeassistant sudo -u homeassistant -H -s cd /srv/homeassistant python3.8 -m venv .

Step 4: Install packages and Home Assistant into Python virtual environment

You are almost done. This is possibly an optional step, but a couple of times in the past I’ve needed to install python packages when I haven’t done this. Use the requirements.txt file you created earlier to reinstall all the packages you had installed in the previous virtual environment.

source /srv/homeassistant/bin/activate cd /home/homeassistant/.homeassistant pip3 install -r requirements.txt

Installing the packages might take a while and you may see some errors or failures, but generally, you don’t have to worry about them (I didn’t and things have always worked fine). Now install and start Home Assistant:

Final thoughts

That’s it. Hopefully, it all goes well. It has for me the couple of times I’ve had to do it. If you’ve decided to run Home Assistant Core in a Python virtual environment you’ll probably have to do this procedure about once a year.
