How do I install it? #57

Closed pkor closed 11 years ago

pkor commented 11 years ago

I have no idea where to begin installing this. I want to use it with kivy on android for the tts module. I can't find any documentation except for how to use it after it's installed. I tried using 'make' but my system doesn't recognize the 'make' command even after installing make. Need more detail on this. Maybe step by step (including installing make).

Pyjnius is shipped in kivy/python-for-android already, no need to do antyhing :). Le 10 avr. 2013 19:45, "pkor" notifications@github.com a écrit :

Thanks! I wasn't aware that it came with python for android. If I want to do testing before running on the android device I'll need to run it under windows? To do that are there some more detailed instructions than the above link?

akshayaurora commented 11 years ago

Download windows package for mysysgit http://code.google.com/p/msysgit/, install it. Run the app. It should open a terminal cd to the directory kivy.bat is located in. type "git clone http://github.com/kivy/pyjnius" This should download pyjnius. now edit kivy.bat and add the path to pyjnius to PYTHONPATH close the terminal.

Now you should be able to import pyjnius in your.py file.

Best Regards

Thank you! The git for windows is great especially the git gui! However in editing the batch file, I see a section 'set PATH' and one 'set PYTHONPATH' . I'm not sure which one to put it under (or if both) or at all how it should look. Should it be like: 'set PYTHONPATH=%kivy_portable_root%kivy;%PYTHONPATH%kivy_portable_root%pyjnius;'?

pkor commented 11 years ago

I tried several variants with the kivy.bat file and finally came up with one that allows me to import 'jnius' but then the debugger says this:

"Traceback (most recent call last): File "~\main.py", line 4, in botstrapping Kivy @ ~\Kivy-1.5.1-w32\ Setting Environment Variables: import jnius File "~\Kivy-1.5.1-w32\pyjnius\jniusinit.py", line 12, in ################################# from .jnius import * ImportError: No module named jnius"

At first glance it looks like the problem is with the initial import but the error is actually in the init.py file of the jnius directory. So it knows where it is but something is wrong from there on. My batch file looks like this now:

"from jnius import autoclass" gives you any error?

Yes, this one:

"done bootstraping kivy...have fun!\n running "python.exe -u ~\main.py" \n Press any key to continue . . . Traceback (most recent call last): File "~\main.py", line 4, in from jnius import autoclass File "~\Kivy-1.5.1-w32\pyjnius\jniusinit.py", line 12, in from .jnius import * ImportError: No module named jnius"

P.S.

I inserted the "~" character in place of the root directory in this comment.

akshayaurora commented 11 years ago

I fear I might have missed a step. Apologies for that.

Double click kivy.bat, this should open a terminal. Type

cd pyjnius
make

This should compile pyjnius and hopefully you'd be able to use it from here on.

Best Regards p.s make sure you have java setup in your path

Thank you for all your help on this. When I run make I get this error:

'C:~\Kivy-1.5.1-w32\pyjnius>make javac jnius/src/org/jnius/NativeInvocationHandler.java process_begin: CreateProcess(NULL, javac jnius/src/org/jnius/NativeInvocationHan dler.java, ...) failed. make (e=2): The system cannot find the file specified. make: *\ [build_ext] Error 2'

Does this mean I don't have java in the path? I have the JAVA_HOME, JRE_HOME and JDK_HOME environment variables set up. Do I need more than this?

akshayaurora commented 11 years ago

It seems that you are using the tools provided with kivy1.5.1, please download the latest packages from kivy.org/download. See if that makes any difference.

Can you run javac from the console? Does it run/throw any error?

I get this:

'C:~\Kivy-1.5.1-w32>javac 'javac' is not recognized as an internal or external command, operable program or batch file.'

I'm guessing that means java is not in the path? I'll try the new version and see where that get's me. Also if pyjnius is needed for so many things, why can't we just have it included in the package? This is alot to go through just to get the access that py4a already has.

I assumed you understood that it is included in python-for-android. as stated by Gabriel earlier. How do you intend to test? I assumed you wanted to test how to make calls through pyjnius by trying to make calls to normal java methods available on a desktop.

If you just want to test how pyjnius can be used on android then just use github.com/kivy/kivy-remote-shell.

This will give you a shell in your desktop that is connected to kivy-remote-shell on your android device. Allowing you to experiment with pyjnus on android.

I actually want both. Our application will be running on desktop and android both using tts, so I'm looking to install it so I can run this abstraction: https://github.com/brousch/saythis-kivy-intro-app/tree/master/saythis/components

pkor commented 11 years ago

I added the environment variable as mentioned above- directing it to the exact path of the javac file and it will not recognize it at all. It recognizes when I type 'java' on the command prompt but there is no environment variable for 'java'. The path I set for the 'javac' variable is: ' C:\Program Files\Java\jdk1.7.0_17\bin'. If I cd to this path and type 'javac' of course it recognizes it. That could only mean that the environment variable is not set, but I know I have it set in system and user variables. What am I doing wrong with this?

akshayaurora commented 11 years ago

Sry to be late in replying on this but I really can't help you much here, I personally don't use windows and wouldn't know how to setup java except maybe follow the official documentation/how to for windows.

I'd make sure you had javac available inside the path you mentioned. Are you sure you have JDK installed and not just JRE? Just to be sure try uninstalling all java packages in your system and then downloading and installing JDK following the instructions from here http://docs.oracle.com/javase/7/docs/webnotes/install/windows/jdk-installation-windows.html#install

After wasting hours on how to set this up properly, this is what worked for me. I have tried to be as verbose as possible.

  1. Download and install jdk (if not installed) http://www.oracle.com/technetwork/java/javase/downloads/index.html
  2. System/Environment Variables (replace jdk1.7.0_79 with your jdk version )
    • Add to Environment Variables:
      • JDK_HOME C:\Program Files\Java\jdk1.7.0_79\
      • PATH C:\Program Files\Java\jdk1.7.0_79\jre\bin\server\
    • Add to System Variables:
      • PATH: C:\Program Files\Java\jdk1.7.0_79\bin\
  3. Install pip (if not installed)
  4. Install Cython (if not installed):
  5. Install Microsoft Visual C++ Compiler for Python 2.7:
  6. Download pyjnius source and install:
dessant commented 8 years ago

@harishankarv, nice work :+1: . This could actually land in the pyjnius installation docs if you want to make a pr for it.

harishankarv commented 8 years ago

I just realized I may have posted in the wrong issue section. Maybe should have posted this here? Anywho, sure thing @dessant, I'll send a pull request!

snoop911 commented 7 years ago

I just installed newer version of kivy 1.9.1, buildozer .32, and Cython 0.21, yet I also get the jnius error:

File "bluetooth_kivy.py", line 15, in from jnius import autoclass ImportError: No module named jnius

(I'm using the example from https://gist.github.com/tito/7432757 )

LCPallares commented 5 years ago

Download windows package for mysysgit http://code.google.com/p/msysgit/, install it. Run the app. It should open a terminal cd to the directory kivy.bat is located in. type "git clone http://github.com/kivy/pyjnius" This should download pyjnius. now edit kivy.bat and add the path to pyjnius to PYTHONPATH close the terminal.

Now you should be able to import pyjnius in your.py file.
