How to use apt-get in EAS build hooks

I’m trying to install some packages with apt-get as mentioned in the Expo docs.

I’ve added the script "eas-build-post-install": "../../scripts/ci/get-translations.sh" in my package.json (using ../../ as my app is in a monorepo) and the get-translations.sh file is being run successfully.

It contains the following lines:

sudo apt-get -y update
sudo apt-get -yq install python-pip
sudo pip install --upgrade pip
sudo pip install transifex-client

The post install script fails with the following output:

[stderr] sudo: apt-get: command not found
[stderr] sudo: apt-get: command not found
[stderr] sudo: pip: command not found
[stderr] sudo: pip: command not found

I also tried running all commands without sudo and still got ‘command not found’ errors.

Please could you explain how to run apt-get in the build hooks?

Here’s a build log in case seen by Expo staff: https://expo.io/accounts/festicket/builds/eb30aac4-bf89-4f55-aa60-a7934f100e5a/logs

there is a lot of options

• based on env $OSTYPE
• output of uname -S
• you can check with command -v apt-get before calling apt-get

For now I’m using a custom env variable called EAS__PLATFORM that I set in eas.json as I couldn’t see any built-in that would do the same here: https://docs.expo.io/build-reference/variables/#built-in-environment-variables
