ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.- when trying to install pyjnius

Question

I have been trying to install pyjnius through the pip command pip install pyjnius and pip install git+git://github.com/kivy/pyjnius.git but all seem to be returning the below error code.

  Collecting git+git://github.com/kivy/pyjnius.git
  Cloning git://github.com/kivy/pyjnius.git to c:\temp\pip-req-build-7d_4quh2

    ERROR: Command errored out with exit status 1:

Please any one give me a solution to this because I am kinda new to this kivy of a thing.

Answer 1

The error message is showing the reason it's failing:

Exception: Unable to determine JDK_HOME

Make sure you have JDK (Java Development Kit) installed. If JDK is installed and it's still not working, try setting the JDK_HOME environment variable to point to the correct location.

Here's where the error message is being thrown, for reference: https://github.com/kivy/pyjnius/blob/7dd6c8e679302526d6e86bdddeca343a3f0b54c7/jnius/env.py#L118-L144
