pyjnius for Windows 10

[Geo Massar]

I am unable to install pyjnius for Windows 10 due to an error message: Unable to find JAVA_HOME. I have already set JAVA_HOME in the system environment. Can anyone help me out? TIA

[Geo Massar]

After some more experimentation, I got a different error message which sees below. Can anyone explain what it meant?

For test purpose:

C:\Users\kawag>echo %JAVA_HOME%

C:\Program Files\Java\jdk-12.0.1\

C:\Users\kawag>javac --version

javac 12.0.1

The result:

C:\Users\kawag>pip install pyjnius

El jdk. 12.0.1 no es coppatible. Usa el jdk 11.0.3 y problema resuelto
