安装python autopy时出错

问题描述

嘿，我在这里看过一个老问题，但它不能回答我的问题

Hey I have looked at and old question here but it doesn't answer my question

我已经安装了libpng，然后尝试安装autopy并遇到compile错误.

I have installed libpng, then try to install autopy and get complie errors.

我还不太擅长python，所以我不确定如何修复它们.

I am not great at python yet so I am not sure on how to fix them.

任何人都可以帮忙.我需要autopy，因为它可以在多个平台上运行

Can anyone help. I need autopy as it works on multiple platforms

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

I used ethan.tira-thompson.com/Mac_OS_X_Ports.html to install libpng

还已通过命令行工具安装了xcode

Have xcode installed with command line tools as well

推荐答案

如果您发现所有9个错误都来自一个文件，则我遇到了同样的问题:src/screengrab.c该文件尚未更新为OpenGL的最新版本，并且有不赞成使用的方法.在autopy github存储库上，有一个关于此此处的错误.有添加行:#include <OpenGL/gl.h>

I had the same problem, if you notice all 9 errors are coming from one file:src/screengrab.cThis file has not been updated to the latest version of OpenGL and there are deprecated methods. On the autopy github repo there is a bug reported for this here. The fix/hack suggested there is to add the line:#include <OpenGL/gl.h>

src/screengrab.c中第7行之后.您将不得不从Github获取源代码并在本地更改它，而不是使用easy_install.
请注意，这是一种hack，可以对其进行编译，但屏幕抓图将全为黑色.有人需要花几分钟用最新的方法重写screengrab.c.

after line 7 in src/screengrab.c. You are going to have to get the source from Github and alter it locally rather than using easy_install.
Note this is a hack that will get it to compile but the screen grabs will be all black. Someone needs to spend a few minutes rewriting screengrab.c with up to date methods.
