no errors on macos, just install by normal way like pip install pemja

Maybe you can check your jdk version or python version which doc suggests

What's the os and hardware? m1 chip?

[andrew-nippard]

Seems to be an issue with how environment variable JAVA_HOME is set on some machines (i.e. I'm using a M1 chip + Linux).

The below command worked for me:
export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-arm64

Okay so i did alot of testing with @jamesalford and it seems this is an error because of python 3.10.

If you install with python3.9 pemja installs fine.

it has nothing to do with java_home being set or not, but its a python issue

Python3.10 works if you set a JAVA_HOME to a working java, otherwise it crashes with NoneType

well，I met the issue in Python3.7，and because the source code of pemja set to find 'JAVA_HOME', so I set 'JAVA_HOME' to solve the problem. Then install pemja successfully.
