使用Anaconda安装“用于Python的MATLAB引擎”的问题

我正在使用Python 3.4.3 | OS X 10.10.5和后续的these instructions to install MATLAB Engine for Python上的Anaconda 2.3.0（x86_64）。安装似乎，但在启动蟒蛇&尝试导入成功，我看到了以下内容：使用Anaconda安装“用于Python的MATLAB引擎”的问题

在研究这个问题，我发现several other references到MathWorks的网站这个确切的问题，都没有解决。最后的链接表明问题可能在dynamic linking。

鉴于许多科学工具箱如何只在MATLAB可用，这将是很有用处的能够调用使用蟒蛇这种发动机。虽然有其他可用的软件包可以支持这种功能，但它们总是具有局限性或其他复杂性，如客户机 - 服务器体系结构。

任何建议是最受欢迎的。

根据我与MathWorks公司的支持通信，MATLAB引擎Python是与蟒蛇不兼容。幸运的是，这是不正确的。

由于从蟒蛇邮件列表的方向，我发现了一个简单的解决方案：

sudo ln -s ~/anaconda/lib/libpython3.4m.dylib /usr/lib

在此之后，matlab.engine成功导入。希望这可以帮助别人！

编辑：OS X 10.11埃尔卡皮坦的，解决办法需要因进行调整，以无根的功能，因为根本不再有权限修改/ usr/lib目录

sudo ln -s ~/anaconda/lib/libpython3.4m.dylib /usr/local/lib

如果我发现了这个一周前回答！ :-)除了添加这个所有重要的链接外，重要的是LD_LIBRARY_PATH不包含anaconda的路径。对于OS X用户来说DYLD_LIBRARY_PATH也是如此......请参阅完整的Anaconda/MATLAB指令，这些指令适用于我：https://stackoverflow.com/a/45161288/2524427 – 5Ke

对于那些在macOS上使用pyenv的人： 'sudo ln -s $ HOME/.pyenv/versions/3.4.7/Python.framework/Versions/3.4/lib/libpython3.4m.dylib/usr/local/lib' –
