JAVA_HOME exporting issue while installing jep through pip3

I am trying to install jep system-wide from pip3 by the following command

sudo pip3 install jep

I get the following error:

 Complete output from command python setup.py egg_info: Error: Please set the environment variable JAVA_HOME to a path containing the JDK. 

Command

python setup.py egg_info failed with error code 1 in /tmp/pip-install-t9lhbx74/jep/

I have already installed openjdk-14 using apt because jep supports Java => 1.3. My bashrc has the following lines:

export JAVA_HOME=/usr/lib/jvm/java-14-openjdk-amd64/

Then I tried to reconfigure java by using

 sudo update-alternatives --config java
There is only one alternative in link group java (providing /usr/bin/java): /usr/lib/jvm/java-14-openjdk-amd64/bin/java.
Nothing to configure.

I tried solution from follwoing questions but no luck:
