http://www.tuicool.com/articles/36ZbI3b 这是我看到的一个 anaconda 安装使用说明，希望可以帮到你，另外你检查了自己的安装步骤和使用步骤么

缺少libpng15. 尝试：
export DYLD_LIBRARY_PATH=/Users/xxx/anaconda/lib:$DYLD_LIBRARY_PATH
不行就去下载个libpng15版本。记得加到librarypath就行了。

@LeoQ thanks!这个是anaconda的重新安装！我按照建议重新安装试一次，非常感谢哈！

[zyceeo]

@sone 非常遗憾的是我是个小白~所以，请问如何将下载到的libpng15加到librarypath呢？

interpreter是选的anaconda的那个python吗？

我之前也遇到过一个问题
symbol lookup error: /usr/lib/i386-linux-gnu/libpangocairo-1.0.so.0: undefined symbol: cairo_ft_font_options_substitute

然后我是这样修复的.
conda update cairo

结果又来一个错误
libpng15.so.15: cannot open shared object file: No such file or directory

我从源码安装了
libpng15

并创建了软链接
sudo ln -s /usr/local/lib/libpng15.so /usr/lib/libpng15.so.15

仅供借鉴.
