在 iO 中安装工具链配方时出现问题

Question

我正在尝试在 iOS 中打包一个 python 应用程序。 该应用程序非常简单，只有 1 行：

from firebase import firebase

我按照此链接的说明进行操作：

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

一切都很好。我使用 Xcode 将应用程序推送到虚拟模拟器。我需要安装一个配方 pycrypto。于是我移到kivy-ios文件夹，按照指示运行以下代码：

sudo ./toolchain.py build pycrypto

失败并出现以下错误（或警告）：

hcaos-iMac:kivy-ios hcao$ sudo ./toolchain.py build pycrypto

我在 VirtualBox 中使用 Mojave，python3。 我不知道为什么一切都“忽略”。 我的应用程序可以在 Linux for android 中成功打包。 我根本不是 Mac 用户。请帮我解决问题。 任何事情都值得赞赏。

看起来 pycrypto 已经从以前的版本编译，所以它没有做任何事情。

编译新配方后，您需要更新项目以将新编译的配方包含到您的项目中，使用以下命令：

./toolchain.py update myproject

另外，请不要使用 sudo，我们从不要求或需要管理员权限。
