toolchain.py build kivy fail

[yanlb]

I´m follow this tutorial https://kivy.org/doc/stable/guide/packaging-ios.html and
when:

$ git clone git://github.com/kivy/kivy-ios
$ cd kivy-ios
$ ./toolchain.py build kivy

give me this error:

ERROR: pbxproj requirements is missing
To install: pip install -r requirements.txt

When run: pip install -r requirements.txt all Requirements already satisfied

and re run: ./toolchain.py build kivy and giveme the same error.

Thanks a lot

I am getting the same error. I should add that when I look at the code for toolchain.py it calls for python3:

#!/usr/bin/env python3

I switched it to 2.7:

#!/usr/bin/env python2.7

And it seems to start but I get the following:

Building with 8 processes, where supported
Want to build ['kivy']

Loaded recipe pyobjus (depends of ['python'], optional are [])

ERROR: No Python version set in the build.
ERROR: Add python2 or python3 in your recipes:

I am pausing for a moment, but I think the solution may be here:

pypi buildozer

FYI pypi buildozer did not help.

I'm getting the same error. When I use the command as suggested in the error message like this /toolchain.py build python2 kivy I get this error after most of the packages are downloaded and compiled:

Hello:

I'm reinstall python, dependencis and then kivy and all work fine now.

Thanks a lot.

I have no idea if this is the right fix (or why it is appearing suddenly), but I can't see how the code in python-future is right here. Here's a potential workaround: PythonCharmers/python-future#423

[hackalog]

@yanlb @ozc @tzujan : Can you try the referenced #332 to see if this fixes your issue?

Note, this workaround will require you install the requests library for python. I believe fixing the existing function requires an upstream fix in python-future (PythonCharmers/python-future#425)

Also getting the same error as @ozc:

AttributeError: '_fileobject' object has no attribute 'readinto'

So after finding that the .zip files "downloaded" were zero bytes it became evident why i would get a BadZipFile Error. Seems like the download fails.

I've just used wget to manually download the zip files that fail. so far have had to do this for kivy,pyobjus,plyer

I already had requests installed so i think that would rule that out

[hackalog]

Having requests installed is not the fix (there's no code to use it by default). Can you try applying #332? You shoud not receive the _fileobject error with this patch. Please let me know if it makes a difference.

I had a fix for the zipfile issue in my tree. The problem is exactly that - a 0 byte zipfile is left hanging around. Let me dig it out and make a PR for it...

[ssolari]

for anyone finding this issue an easy fix is to use miniconda or anaconda and create a conda environment. The issue is that the module inside the requirements.txt file, namely pbxproj==2.5.1 needs to be installed in the local environment.

a fix is to create a conda environment, then activate that environment and run all building within that environment

Assuming you have miniconda installed.

environment.yml file

# Use this to create the initial environment for kivy-ios
channels:
  - https://conda.anaconda.org/conda-forge
dependencies:
  - cython==0.29.1
  - python=3.7.1
  - pip:
    - kivy==1.10.1
    - pbxproj==2.5.1

then

>> conda env create -n kivyiosenv -f environment.yml
>> conda activate kivyiosenv
>> ./toolchain.py build kivy

the version for cython and python should be changed if creating a python2 environment.
Note, if you want to use ./toolchain pip install ... careful for modules like requests that are already installed in the conda environement #347.

[hackalog]

@ssolari Thanks for that! It's not a complete workaround, however. Many of the recipe builds will fail, as they also require downloads (and will use the urlretrieve code path to do them).

That said, I do have a cookiecutter I use for starting a kivy project, whose template is a superset of what you have done above. I'll think you've encouraged me to clean it up and share it on github.

[ssolari]

@hackalog that would be cool. Easier end to end solutions without the environment concerns I think will lead to happier users.

I also think the recipes could benefit from switching to using conda recipes instead #345

[ssolari]

also @yanlb @tito should this issue be closed?

[yanlb]

Thanks a lot

[mc0ps]

Same thing happened to me, fixed it by specifying python2:
./toolchain.py build python2 kivy
