Matlab Engine Python - iPython 出现 OSx Anaconda Segfault 或 DYLD_LIBRARY_PATH 错误

Question

在终端中安装 matlab python 包后，使用：

cd "matlabroot\extern\engines\python"
python setup.py install

尝试运行它时，出现段错误：

:~$ python
Python 2.7.10 |Anaconda 2.3.0 (x86_64)| (default, May 28 2015, 17:04:42) 
[GCC 4.2.1 (Apple Inc. build 5577)] on darwin

>>> import matlab.engine
Segmentation fault: 11

但是，我可以通过设置 DYLD_LIBRARY_PATH 来解决这个问题，然后 matlab.engine 就可以工作：

:~$ export DYLD_LIBRARY_PATH=/System/Library/Frameworks/Python.framework/Versions/Current/lib:$DYLD_LIBRARY_PATH
:~$ python
Python 2.7.6 (default, Sep  9 2014, 15:04:36)

Type "help", "copyright", "credits" or "license" for more information.
>>> import matlab.engine
>>> eng = matlab.engine.start_matlab()
>>> exit()

但是，当我随后尝试启动 iPython 时，出现此错误：

Traceback (most recent call last):

    from IPython import start_ipython

正如你所看到的，Python 版本是不同的。我认为这是我的系统 Python 和 Anaconda 之间的冲突，但我不知道如何修复它，非常感谢任何帮助。谢谢。

您需要使用 conda 命令行安装实用程序安装库，而不是 python。conda help search并且conda help install应该让你继续前进。
