I just followed the top-voted answer here and successfully installed Visual Studio Code's code command in my terminal.
However, the code command fails to launch Visual Studio Code every time after I restart my MacBook Pro.
~ code
zsh: command not found: code
Is it possible to install code permanently so that I don't have to install it every time I turn on my MacBook Pro?
~ where code
/usr/local/bin/code
~ ls -l /usr/local/bin/code
lrwxr-xr-x  1 myName  admin  167 Aug  5 13:41 /usr/local/bin/code -> /private/var/folders/bh/525lnbns1213cx2651s97my00000gp/T/AppTranslocation/EA379FC4-05D2-4739-BE49-1D8870E47B8A/d/Visual Studio Code.app/Contents/Resources/app/bin/code
I also find out that the folder EA379FC4-05D2-4739-BE49-1D8870E47B8A get deleted after I restart my laptop. 
This is the reason that I cannot run code after the laptop is restarted.
Why is code installed in a temporary folder? 
My MacBook Pro's version is macOS Sierra version 10.12.6
