无法访问$ LD_LIBRARY_PATH

Question

没有重新导出$ LD_LIBRARY_PATH，也没有对bashrc中的变量做任何事情，

echo $LD_LIBRARY_PATH

返回

/usr/local/cuda/lib64

然而，

$LD_LIBRARY_PATH

返回

-bash: /usr/local/cuda/lib64:: No such file or dictionary

然而，这条道路确实存在。

可能出了什么问题？

------ ----- EDIT

ls -ld /usr/local{,/cuda{,/*}}

返回

Answer 1

通过修改Makefile.config解决了问题，如下所示：

/usr/local/cuda 

到

/usr/local/cuda-7.5
