问题描述
我正在尝试使用网站中的说明在iOS中打包一个简单的Kivy应用程序:
I am trying to package a simple Kivy app in iOS using the instruction in the site:
https://github.com/kivy/kivy-ios
我的应用非常简单，只有1行:
My app is very simple with 1 line:
from firebase import firebase
该应用程序可以使用linux在android中成功打包.但是，我在将其打包到iOS时遇到了问题.我需要建立一个名为pycrypto的食谱，但它给了我以下错误.我尝试了python2和python3.我仍然遇到相同的错误.网址链接似乎已失效( https: //ftp.dlitz.net/pub/dlitz/crypto/pycrypto/pycrypto-2.6.1.tar.gz )
The app can be packaged successfully in android using linux. However, I am having problem packaging it to iOS. I need to build a recipe named pycrypto but it's giving me the below error. I tried both python2 and python3. I still ended up with the same error. It seems the url link is dead (https://ftp.dlitz.net/pub/dlitz/crypto/pycrypto/pycrypto-2.6.1.tar.gz)

推荐答案
可以在 https://github.com/kivy/kivy-ios/issues/384 可以构建Pycrypto，但无法正常运行.解决方法是完全避免使用firebase(需要pycrypto).使用request和json代替简单的get和post方法.
Answer can be found at https://github.com/kivy/kivy-ios/issues/384Pycrypto can be built but it won't run properly. The workaround is to avoid firebase (which requires pycrypto) altogether. Use requests and json instead for simple get and post methods.
