安装 python autopy 时出错

Question

嘿，我在这里看过一个老问题，但它没有回答我的问题

我已经安装了 libpng，然后尝试安装 autopy 并得到编译错误。

我还不是很擅长 python，所以我不确定如何修复它们。

谁能帮忙。我需要 autopy，因为它适用于多个平台

我使用 ethan.tira-thompson.com/Mac_OS_X_Ports.html 来安装 libpng

还使用命令行工具安装 xcode

Answer 1

我遇到了同样的问题，如果您注意到所有 9 个错误都来自一个文件： src/screengrab.c 此文件尚未更新到最新版本的 OpenGL，并且有一些已弃用的方法。在 autopy github repo 上报告了此 here. 的错误，修复/hack 建议添加以下行： #include <OpenGL/gl.h>

在 src/screengrab.c 的第 7 行之后。您将不得不从 Github 获取源代码并在本地进行更改，而不是使用 easy_install。
请注意，这是一个可以编译的 hack，但屏幕抓取将是全黑的。有人需要花几分钟用最新的方法重写 screengrab.c。

Answer 2

当我添加时

#include <OpenGL/gl.h>

它没有编译。

所以，我查看了我的硬盘，寻找每个gl.h

所以，我试过了

    #include "/System/Library/Frameworks/OpenGL.framework/Versions/A/Headers/gl.h"

然后我设法编译它:-)

Answer 3

如果你试过这个：

$ sudo easy_install 自动安装

另一种选择是从 GitHub 存储库上的最新源编译：

$ git clone git://github.com/msanders/autopy.git

$ cd 自动复制

$ python setup.py build

$ python setup.py 安装

从源代码构建时，请确保在尝试使用 AutoPy 之前 cd 退出 autopy 目录，否则由于 Python 的相对导入，它可能会在 ImportError 上失败。
