Hi!

Welcome to the forum @Erfan
Please copy/paste text rather than screenshot. The bit we need to see is off the top. Please start node red and copy paste everything from the welcome message to the end of the error. Also tell us what hardware and OS you are running on.
Edit, also see this issue against the node.
Hi, i test it both on windows and Linux(ubunto)
this message is from cmd windows:

@Colin
Actually this my be the first time I prefer the picture over the code 
I see that the return prompt is for
~Desktop$
When I would expect it to be
~/.node-red $
or
~/Desktop/.node-red $
Good day @Erfan
I am the creator of node-red-contrib-facial-recognition
I believe you are trying to install this in the wrong location
I'm not a windows guy. have not used it for over a Decade. So all my advice will be based from the linux command line.
You need to be in your node-red directory before issuing the command
npm install node-red-contrib-facial-recognition
Please make sure of this first. If you want to know how I deduced this, i've ran node stuff from the wrong version directory before and got similar messages. This all leads me to believe you are in the wrong dir.
Also ... is there a reason you are installing via the command line instead of using node-red's pallet/install manager?
NOTE!!!!
I just realized this is not my package.
I created node-red-contrib-facial-recognition
This is for node-red-contrib-face-recognition
Besides the wrong location, there is also the mismatch of some native code.
So it got initially installed with an older version of nodejs.
Try a fresh install in the correct location.
u see ~Desktop$ it is because of when i start to add images into face-recognition it crashes! and send me off and node-red get closed :))
what do you mean? 'correct location??'
i didnt understand i should install older versioin? or newer
Please show what you see when you start node red in a Linux system. The full startup output please from the Welcome to node red message.
Hi
- because i am winows i use ubuntu in vmware and thats why i use node-red on port 1882 *

Did you follow the directions in the node's README about installing the prerequisites for Canvas?
Canvas
Canvas will be installed correctly providing when using either installation method, however the required packages need to be installed on the system. These are as follows for several common OS's;
