来自 freetype 2.5.3 的 libPng.dylib 的问题 [英] Trouble with the libPng.dylib from freetype 2.5.3

问题描述

我已经在 OS X (10.9.4) 上的本地目录中安装了 freetype-2.5.3，我将所有科学软件 (/Users/t/Science/local) 都放在其中，现在我的其他代码遇到了问题，即

I have installed freetype-2.5.3 on OS X (10.9.4) in my local directory in which I park all science software (/Users/t/Science/local), and now my other codes are running into trouble, i.e.

Xcode 路径好像没问题.如何让系统中的 libPng.dylib 再次成为默认值?

The Xcode path seems to be okay. How do I get libPng.dylib from my system to be the default again?

非常感谢！

推荐答案

我遇到这个问题是因为我用 brew 安装了 libpng.运行以下命令解决了问题:

I had this problem because I installed libpng with brew. Running the following command solved the problem :

brew uninstall libpng

如果你同时需要默认的 mac libpng 和这个...祝你好运.我不得不经常用 brew 安装/卸载 libpng.

And if you need both the default mac libpng and this one...good luck. I had to install/uninstall libpng with brew oftently.
