window after installing Anaconda, Conda is not an internal or external command

Today, when installing Theano, you need to look at what packages Anaconda have installed. Use the command as follows, in the console, cmd enter input can:
conda list
However, the display error, "Conda is not internal or external command", first instinct, environment variables are not, here can also be in cmd input:
path
To view existing environment variables.
But!!! , you will find that you are already equipped with environment variables (which are actually not complete), and the environment variables you see are:
....; xxx\Anaconda2
Then it feels that the environment variable has been paired. In fact, this is not complete, and you need to add another environment variable after this:
;xxx\Anaconda2\Scripts
Here XXX represents your Anaconda installation path Many people like to install on the D-disk, that is, after the environment variable add: (concrete steps, My Computer-system Properties-Advanced system Settings-advanced-environment variables-System variables-find path, add the following sentence, save)
;D:\Anaconda2\Scripts
Can now be successfully entered in CMD console
conda list
