无法安装buildozer

Question

I was trying to install a tool called Buildozer that is used to compile python kivy programs into APKs.

I used

pip3 install --user --upgrade buildozer

as the installation guide said but that error occurred:

C:\Python3\Scripts>pip install buildozer
Collecting buildozer
  Using cached buildozer-1.4.0-py3-none-any.whl (84 kB)
Collecting sh
  Using cached sh-1.14.3.tar.gz (62 kB)
  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error

  × python setup.py egg_info did not run successfully.

          import fcntl
      ModuleNotFoundError: No module named 'fcntl'
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

× Encountered error while generating package metadata.
╰─> See above for output.

note: This is an issue with the package mentioned above, not pip.
hint: See above for details.

I tried to install another version of python but it didn't work.

If someone can help me I will be grateful.

Buildozer can't be used directly under Windows. It can be used on Windows running Ubuntu Linux via WSL. The official installation instruction can be found here:

https://buildozer.readthedocs.io/en/latest/installation.html

It recommends installing Java 17 but I personally had an issue with JDK 17 thus I recommend to install JDK 11 instead.

1. Install Ubuntu 22.04.xx LTS from Microsoft Store

   https://www.microsoft.com/store/apps/9PN20MSR04DW

2. Run installed Ubuntu (terminal window) from Windows Start Menu or using PyCharm Terminal:

   

3. Install Buildozer on Ubuntu by running following commands:

    sudo apt update sudo apt install -y git zip unzip openjdk-11-jdk python3-pip autoconf libtool pkg-config zlib1g-dev libncurses5-dev libncursesw5-dev libtinfo5 cmake libffi-dev libssl-dev pip3 install --user --upgrade Cython==0.29.19 virtualenv echo "export PATH=\$PATH:~/.local/bin/" >> ~/.bashrc pip3 install --user --upgrade buildozer

4. Now make sure your current Ubuntu directory is set to your Python project's directory. If for example your project is stored within: C:\Kivy\Projects\MyHelloWorld , then change your Ubuntu current directory to /mnt/c/Kivy/Projects/MyHelloWorld :

    cd /mnt/c/Kivy/Projects/MyHelloWorld

   Note: using PyCharm terminal it will always set current directory to your project's folder

5. Make sure that your Windows user have Full Control access right to your project's folder under Windows

6. Generate initial buildozer.spec for your project under Ubuntu terminal:

    buildozer init

7. Change buildozer.spec lines:

    # android.accept_sdk_license = False

   to

    android.accept_sdk_license = True

   and

    #android.api = 27

   to

    android.api = 33

8. You can build your project using for example:

    buildozer -v android debug

First build attempt will take more than half an hour, because Buildozer will collect required stuff over inte.net into .buildozer folder of your Python project. Next build attempts will be more quicker.
