我阅读了以下说明,以便使用 matlab 代码创建 python 应用程序:Create a Python Application with MATLAB Code
一切正常,当我执行命令python setup.py install
时,会显示以下消息:

然后,当我尝试导入 Matrices_Clifford 时出现错误:
import Matrices_Clifford
Exception caught during initialization of Python interface. Details: On Linux, you must set the environment variable "LD_LIBRARY_PATH" to a non-empty string. For more details, see the package documentation.

RuntimeError: On Linux, you must set the environment variable "LD_LIBRARY_PATH" to a non-empty string. For more details, see the package documentation.
如何解决这个问题?
最佳答案
这个错误是不言自明的。必须定义环境变量LD_LIBRARY_PATH
,以便操作系统知道库的位置。使用setenv command正确定义它,如下所示:
setenv LD_LIBRARY_PATH path/to/libraries
看来this link可以为您指明正确的路径(没有双关语),并且所需位置的格式为 matlabroot/bin/glnxa64:matlabroot/sys/os/glnxa64
。
