CUDA: nvcc cannot be detected installation

[Benson]

Hello,
I successfully installed the latest version cuda8.0. But when I type the command "nvcc --version" it says to me that

The program 'nvcc' is currently not installed.

What do I need to do now?

[Luca]

Run which nvcc see if it returns anything.

Run which nvcc see if it returns anything.

No it didn't return

[Luca]

It means either nvcc didn't install properly or is not in your PATH, find where it is installed with whereis nvcc

[Benson]

I tried but it only shown "nvcc: "

[Luca]

To make sure, close and launch terminal and try nvcc --version

Can you find where nvcc is installed on your filesystem? If you can, is that path actually in your $PATH?

[Benson]

To make sure, close and launch terminal and try nvcc --version

No nothing happened

[Hadley]

Can you please post the output of the echo $PATH command?

[Benson]

Sorry, I have just noticed that I didn't actually add cuda to my current user's path.
Now the problem has been fixed.

Please add your solution as an answer so it will help to the others.

In fact, it's the situation that I set the environment variable in a wrong way. As a replacement for

$ export PATH=/usr/local/cuda-7.0/bin:$PATH
$ export LD_LIBRARY_PATH=/usr/local/cuda-7.0/lib64:$LD_LIBRARY_PATH

as it's recommended, I select to edit /etc/profile, which is not recommended.
