无法在python3中建立pycrypto配方-工具链 [英] Unable to build pycrypto recipe in python3 - toolchain

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)

Answer can be found at https://github.com/kivy/kivy-ios/issues/384 Pycrypto 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.
