Kivy-ios: 工具链构建 python3 Kivy 错误

Question

我按照 these instructions 在我的 virtualbox macOS Big Sur 虚拟机中构建了 Kivy 和其他食谱。当我运行 toolchain build python3 kivy 或 toolchain build kivy 时，我遇到了以下错误。有什么建议吗？非常感谢。

Answer 1

您的 _init_.py 文件在 freetype 文件夹中（例如，/Library/Frameworks/Python.framework/Versions/3.x/lib/python3.x/site-packages/kivy_ios/recipes/freetype/_init_.py)指的是过时的URLlink，所以你只需要编辑文件，修改“url = "喜欢,

class FreetypeRecipe(Recipe):
    version = "2.5.5" 
    url =  "http://download.savannah.gnu.org/releases/freetype/freetype-{version}.tar.bz2" 
    library = "objs/.libs/libfreetype.a" 
    include_dir = ["include", ("builds/unix/ftconfig.h", "config/ftconfig.h")] 
    include_per_arch = True

Answer 2

亲爱的 Taka（参考 Taka 的 post），非常感谢。这是我几个月来见过的最好的答案。你的方法在我的 MAC 和我的 MAC VM 上保存了 kivy。发生的事情是版本 freetype-2.5.5 被移动到 savannah 站点上的另一个子文件夹。较新的版本是 2.10.0。这就是我解决问题的方法：

进入init.py，更新版本=“2.10.0”。我不能只是运行 toolchain build python3 kivy。这将再次抛出错误。
那我得去网站下载freetype-2.10.0.tar.bz2 文件并将其保存在 .cache/ 文件夹中。这是如何去 MAC 中的 .cache 文件夹。前往 Finder -> 前往 -> 前往文件夹 -> 输入 /users/{用户名}/.cache

Answer 3

解决此问题的一种方法是从此处下载预期的 freetype 包：

https://download-mirror.savannah.gnu.org/releases/freetype/freetype-old/freetype-2.5.5.tar.bz2

然后将其移动到预期位置。所以在你的情况下，你可以运行:

mv ~/Downloads/free-type-2.5.5.tar.bz2 ~/kivy-ios/.cache/freetype-freetype-2.5.5.tar.bz2

然后重新运行构建，它将解决这个问题。

不过，我认为这个错误可能表示环境问题。您应该验证您使用的 Python3 版本是否适用于 Kivy（目前是 3.7.x）。检查 python3 --version.
