不能访问$ LD_LIBRARY_PATH

-1

没有重新出口$ LD_LIBRARY_PATH，并没有在.bashrc中的变量做任何事情，

echo $LD_LIBRARY_PATH

回报

/usr/local/cuda/lib64

然而，

$LD_LIBRARY_PATH

回报

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

然而，路径确实存在。

什么可能会出错？

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

这与CUDA无关，所以我删除了标签 – talonmies

如果您只需输入'$ LD_LIBRARY_PATH'，它将展开该变量，然后bash将尝试运行它。你究竟在做什么？ –

@JonathonReinhart我在跑咖啡时遇到了一个路径问题，所以我想我可能会考虑它。在caffe上运行make runtest返回libcudart.so.6.0未找到 – ytrewq

这个问题是通过修改Makefile.config如下解决：

/usr/local/cuda

至

/usr/local/cuda-7.5
