Can I run a Kivy program from within Pyscripter?

I've entered this code in Pyscripter:

import kivy

kivy.require('1.7.2')

from kivy.app import App

from kivy.uix.label import Label

class MyApp(App):

      def build(self):
          return Label(text='Hello Kivy')

MyApp().run()

I then press the Run button (the green triangle). I get the following error:

Import error: No module named kivy

What can I do to make this work?

P.S. I know I can leave Pyscripter and use kivy.bat, but I would like to use the debugging capabilities within Pyscripter.

Solution

I think this is probably because kivy.bat really sets up and uses a second python distribution that has kivy installed. However, pyscripter is using your normal system installation, which does not have the kivy module installed.

You can probably tell pyscripter to use the kivy interpreter with the right environment set up. I don't know how exactly (I haven't ever tried on windows), but for instance this previous question is similar but about pycharm rather than pyscripter. I have pasted the answer below, some of it relates specifically to pycharm but something similar will probably work for pyscripter.

Install and open PyCharm
If you already had it installed and have a project open, click File -> Settings (Ctrl + Alt + S). (If not, create a new project, and
click the '...' next to interpreter, and skip step 2) Under Project Settings, click Project Interpreter -> Python Interpreters Click the little green + and select local (You can also set up an interpreter to your installed python from this list) Point it to ..\Kivy\Python\python.exe and click ok (Mine's path was c:\Program files (x86)\Kivy\Python\python.exe since that is where I unzipped the kivy zip file to)

I have also attached a settings.jar file here https://groups.google.com/forum/#!topic/kivy-users/xTpib2C8r_A. This is the kv language definition. Its not complete, but it helps a lot. Click File->Import-> Select the settings.jar file. Only FileTypes will be ticked. import this and you will have "kv language file" definition under File->Settings-IDE Settings->File Types

Open a kv file to see the differentiation in colours, as well as autocomplete Widgets are type 1 Properties are type 2 all events (on_something) are type 3 type 4 is just self and root.

-- That is all for PyCharm, the rest is Windows 7 specific things. -- 1. open a command prompt and browse to your ..\Kivy\Python\lib folder 2. type mklink /D kivy "..\Kivy\kivy\kivy" (Mines line was mklink /D kivy "c:\Program files (x86)\Kivy\kivy\kivy") This will set up a symlink so that your all your kivy python files are read and their definitions are included, in order to get autocomplete

Now we need to set up the environment variables. You could do this per project inside PyCharm, but might as well do it in windows, so you only need to select the python interpreter each time Click start and type envir Select the second one. (System variables) ( You could also get here with Win+PauseBreak-> Click Advanced system settings) Click Environment variables

Now add these (Once again, just point to wherever you have your kivy folder. You can also find all these in the kivy.bat file, just find and replace the variables with your path)

GST_PLUGIN_PATH c:\Program Files (x86)\Kivy\gstreamer\lib\gstreamer-0.10

GST_REGISTRY c:\Program Files (x86)\Kivy\gstreamer\registry.bin

PATH c:\Program Files (x86)\Kivy;c:\Program Files (x86)\Kivy\Python;c:\Program Files (x86)\Kivy\gstreamer\bin;c:\Program Files (x86)\Kivy\MinGW\bin;c:\Program Files (x86)\Kivy;c:\Program Files (x86)\Kivy\Python;c:\Program Files (x86)\Kivy\gstreamer\bin;c:\Program Files (x86)\Kivy\kivy;%PATH%

Restart your machine. (For the environment variables to load)

Now when you open your kivy project, just select the Kivy interpreter you set up earlier, and bobs your uncle.

You can also try to install kivy in your existing python installation. The kivy website has instructions for this here. I haven't tried this, and there may be some tricky bits.
