Can't install pyjnius 1.12

[J. Z. D.]

Hello,

Thank you for trying to help me !

 

I'm actually trying to make an application, controlling bluetooth relay,

 

I'm on Windows 10, I got updated JDK and JRE, then installed without any problem kivy and cython,

But installing pyjnius, I've got a lot of error, is it about x64 ? still about java ?

 

This is my latest error, but i can’t know what to try next !

 

Thanks again !

 

Jzd

I should precise, I'm using Python 3.7, 64 bits (like Windows), JDK-13, JRE-1.8.0_221.

[Alexander Taylor]

Do you actually want to use pyjnius on the desktop, or on Android?

[J. Z. D.]

Hey, on the computer to make the application program.

[ZenCODE]

Try using JDK-8? That version should work?

[Emilia J]

Hello.

I also can't install pyjnius -.- I've been trying to figure it out for a few hours :/ 

setuptools up-to-date

But I still get the error:

C:\Users\Emilia>pip install pyjnius

What else am I supposed to do?

[Robert Flatt]

I tried installing pyjnius on Windows

Python 3.6 and Java SE development kit installed - installs OK

Python 3.8 no Java SE   - install fails "unable to find JAVA_HOME" , as expected because Java SE is not installed.

So the could be python version related, or not - more testing needed.

Or I notice that my Python 3.6 machine does not have %JAVA_HOME% , %JDK_HOME%, or %JSE_HOME% defined (as shown by echo)

So un-defining these would be something to try, as the error messages are about finding "possible_homes"

[Emilia J]

Thank you for your reply, but environment variables are set. os.environ.get() works and can find JAVA_HOME, JDK_HOME etc., so it must be something else.

Btw I use Python 3.7, but JRE is installed, so i'll try to install JDK.

[Robert Flatt]

Perhaps I was not clear.

I get that the *_HOME variables are set.

Try unsetting them, though sensible to you and me that they should be set, perhaps not to the install (as shown by not required on my machine)

And yes Python version is a possibility, but at this point insufficient evidence.

[Emilia J]

But when the variables were not set, I got the JAVA_HOME or JDK_HOME error. 

I tried with JDK 8 and 13 and there is still the error "PermissionError: [WinError 5] Access is denied":

I reinstalled pyjnius and notice the file pip used is a wheel not a tar file. Your pip acting like Linux not Windows.

My pip gets:

https://files.pythonhosted.org/packages/23/03/d783dadd3bb2c8adedb6eff375c57f97afa3059df1814646f74dc3463161/pyjnius-1.2.1-cp36-cp36m-win_amd64.whl

Is there more than one pip on the system?

pip --version

will show the file is actually being used

[Emilia J]

I tried this wheel, but no changes. I upgraded pip a few days ago, so it's up-to-date. I also thought that there may be a problem with pip and I checked it, but everything seems right.

pip --version >> pip 20.0.2 from c:\python37-32\lib\site-packages\pip (python 3.7)

and I don't see any other version in C:\Python37-32\Lib\site-packages. 

Maybe pycharm still uses that older version?

[Robert Flatt]

That wheel is not going to work for you because it is 64 bit, and your python is 32 bit

Is there a pip elsewhere, such as GunWin32?  Look at all the path entries.

I don't understand the reference to pycharm (which I don't use), I'm assuming the behavior is from the cmd prompt.

[Emilia J]

Idk why I installed python 32-bit not 64-bit, but however I have both xD 64bit is shared by Microsoft Visual Studio and there is the previous version of pip.

Does it cause the problem?

[Emilia J]

I reinstall python and pyjnius was installed successfully, but I see there is some problem with pip. Python has default pip version -19.2.3 and when I upgraded that, pip didn't replace with pip 20.0.2 in site-packages directory, so if I use a general command pip install, there older version is invoked, but python -m pip install uses 20.0.2, so generally it's ok.
