ModuleNotFoundError: no module name kivy

Hi, When I try running the code below and use the instructions here to produce an ios app, I run into a ModuleNotFoundError: no module name kivy (line 1) and the app closes abruptly.

I followed the instructions in this repo. Could someone please share what could be going wrong?

Many thanks, Jaspal

What you did didn’t work for me either. So I cloned the repo and followed those instructions. I had to edit toolchain.py because I was having some issues with the original one. But here’s what I did:

Section 1

$ cd ~ # Or any directory
$ git clone git://github.com/kivy/kivy-ios
$ cd kivy-ios
$ nano toolchain.py

• Add #! /usr/bin/env python3 to the beginning of the file.
• Now is a good time to create a virtual environment by running virtualenv venv if you want to. You might need to run pip install virtualenv to install the virtualenv tool.
• To install kivy-ios’s dependencies, run pip install -r requirements.txt. Then run:

$ chmod +x toolchain.py
$ ./toolchain.py build kivy

A few seconds or minutes later, you will get an error. If your build takes a very long time and succeeds (you don’t get an error), awesome! Skip the rest of this section and continue to Section 2.

So run:

$ nano kivy_ios/toolchain.py

• Import requests where the other imports are located.
• In the Recipe.download_file method, replace

try:
    urlretrieve(url, filename, report_hook)
except OSError:
...

with

try:
    with open(filename, 'wb') as filename_:
        filename_.write(requests.get(url).content)
except:
...

Make sure you indent with spaces. Then run:

$ ./toolchain.py build kivy

After a long time, this command should finish successfully.

Section 2

Now run:

$ ./toolchain.py recipes

You can see the libraries that you can ./toolchain.py build. For each package that your app requires: If the package was listed when you ran ./toolchain.py recipes, run:

$ ./toolchain.py build <PACKAGE>

NOTE: Your app will require python3.

If it wasn’t, run:

$ ./toolchain.py pip install <LIBRARY>

Section 3

Now you are almost ready. Run:

$ ./toolchain.py create <PROJECT_NAME_WITH_NO_SPECIAL_CHARS> <CODE_DIR> # Note: There should be a main.py in your code directory
$ open .

In Finder, right click on your <PROJECT_NAME_WITH_NO_SPECIAL_CHARS>-ios folder and click “Get Info.” Now click the lock on the bottom right corner of the window and type in your password. Under “Sharing & Permissions,” change all permissions to “Read & Write.” Click the settings icon in the bottom left of the window and click “Apply to enclosed items…” Click “OK” to apply the changes. Move one folder up and right click on the kivy-ios folder that you got from GitHub. Click “Get Info.” Click the lock on the bottom right corner of the window and type in your password. Under “Sharing & Permissions,” change all permissions to “Read & Write.” Click the settings icon in the bottom left of the window and click “Apply to enclosed items…” Click “OK” to apply the changes. Now in your terminal, run:

$ open <PROJECT_NAME_WITH_NO_SPECIAL_CHARS>-ios/<PROJECT_NAME_WITH_NO_SPECIAL_CHARS>.xcodeproj/

Now, you probably know what to do in Xcode. I hope this comment helps you!
