Kivy Garden Filebrowser Install Error

[Yowser MaGuil]

First: hello to all in the group! I am an app developer new to Kivy. I have been using python for 3 years.

Currently I am trying to install Kivy Designer based on instructions found here:: https://github.com/kivy/kivy-designer

When I attempt to install the Filebrowser via "garden install filebrowser", I am getting the following message:

Downloading http://github.com/kivy-garden/garden.filebrowser/archive/master.zip ...

Traceback (most recent call last):

  File "/usr/bin/garden", line 189, in <module>

    GardenTool().main(sys.argv[1:])

  File "/usr/bin/garden", line 71, in main

    options.func()

  File "/usr/bin/garden", line 109, in cmd_install

    fd = self.download(opts.package)

  File "/usr/bin/garden", line 170, in download

    data += buf

TypeError: Can't convert 'bytes' object to str implicitly

 Using Arch Linux, Python 3, Kivy 1.8.

Thanks

I don't think the projects in the kivy-garden have all been ported to Python3 yet, only Kivy itself. Try it with Python 2.7 and see if it works.

This is not a problem with kivy package. It's the bytesstring to string conversion which python3 doesn't like. The code is dyning post the download and fixing it to the string using decode may not be an option. 

the data is initialized as data = '' which is a string. r represts the binary content and should be treated as bytes and not string s

        for buf in r.iter_content(1024):

            index += 1

            data += buf <== dying here 

            count += len(buf)

            print('Progression', count, animation[index % len(animation)], '\r')

            sys.stdout.flush()

        print('Download done ({} downloaded)'.format(count))

potential fix to the problem 

change your garden python script to 

  data = b''  # initialize as a byte buffer 

        for buf in r.iter_content(1024):

            index += 1

            data += buf  # the error would go away

            count += len(buf) 

            print('Progression', count, animation[index % len(animation)], '\r')

            sys.stdout.flush()

        print('Download done ({} downloaded)'.format(count))

        

        return BytesIO(data) change string io to BytesIO 

this would require  import at the top of the script 

from io import BytesIO
