ios - 无法在 python3 中构建 pycrypto 配方 - 工具链

Question

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:

https://github.com/kivy/kivy-ios

我的应用程序非常简单，只有 1 行:

from firebase import firebase

在android下使用linux可以成功打包app。但是，我在将其打包到 iOS 时遇到问题。我需要构建一个名为 pycrypto 的配方，但它给了我以下错误。我尝试了 python2 和 python3。我仍然遇到同样的错误。看来 url 链接已失效 ( https://ftp.dlitz.net/pub/dlitz/crypto/pycrypto/pycrypto-2.6.1.tar.gz )

Answer 1

答案可以在 https://github.com/kivy/kivy-ios/issues/384 找到Pycrypto 可以构建，但无法正常运行。解决方法是完全避免使用 firebase(需要 pycrypto)。使用 requests 和 json 代替简单的 get 和 post 方法。
