pyjnius 'JAVA_HOME' error

[Miftah]

Hello,

I am having trouble with pyjnius while trying to execute the following code;

import jnius

I am getting the following error;

Traceback (most recent call last):
  File "/home/miftah/Desktop/ble_kivy_2/main2.py", line 3, in <module>
    import jnius
  File "/usr/local/lib/python2.7/dist-packages/jnius/__init__.py", line 13, in <module>

  File "/usr/lib/python2.7/UserDict.py", line 40, in __getitem__
    raise KeyError(key)
KeyError: 'JAVA_HOME'

if I type      echo $JAVA_HOME      in my terminal, I get

/usr/lib/jvm/java-8-openjdk-amd64;

But again,

import os
print(os.environ.get('JAVA_HOME'))

gives 'None'

Would you please suggest what can I do ??

Thank You

Make sure the variable is "exported," which makes it available to sub processes.
