pip3 install javabridge error in Raspberry Pi

[phinjomcent]

Hello
I'm having trouble installing javabridge in my Raspberry Pi 3B+ (Raspbian Buster).
I followed the instructions from the javabridge website and this forum stated above, but to no avail. I also followed the export command but the problem still persists. The error message is shown below and I hope this may be helpful:

`

Hoping for a response, Thank You!

Hi, sorry you're having problems. I think you might be the first person to install on an ARM processor. There's some code in the setup script to look for the processor-specific directory which has the correct libjvm.so files for Java.

Could you do me a favor and give me the output on that system of:
find /usr/lib/jvm/java-11-openjdk-armhf -name libjvm.so

Hello and thank your for response. The output of that command is:
/usr/lib/jvm/java-11-openjdk-armhf/lib/server/libjvm.so

I have to admit, I'm a bit flummoxed by this one. The code to locate libjvm.so should detect that. I doubt it will help, but you might try installing the latest version:
pip3 install https://github.com/LeeKamentsky/python-javabridge/archive/master.zip#egg=python-javabridge
Meanwhile, I'll think about it some more and see if I can figure out why it's not working.

Sorry for the late reply, but as I tried installing the latest version as mentioned above, the error message is still the same. :(
