I use windows10.
My node.js's path is C:\Program Files\nodejs\node.exe and I can use node command.
But I haven't set my environment variable path.
It does not mean just that I have not set it myself. I checked the user environment variables and the system environment variables but could not find them. (The path of npm was in the user environment variable.)
Why can I use node command without setting path?
For the node command to work in Windows from a command shell, one of the following must be true:
Your current directory in the command shell is C:\Program Files\nodejs and thus node.exe or node.bat can be found in that current directory.
C:\Program Files\nodejs is in the search path which can be either a system wide path setting or a local user path setting (what you see in the environment is a combination of those two).
There is a node.bat file somewhere in your system path or in the current directory that launches node.exe for you by directly referencing its path.
On Windows, you can type "where node" in the command shell and it will tell you where it's finding the file to run. If what it is finding is not in the current directory, then you must have its directory in your path somewhere.
where node and get C:\Program Files\nodejs\node.exe. I can't find neither node.bat nor node.exe in current directory. (current dir is C:\users\user). And I also can't find environment variable path to C:\Program Files\nodejs.
path. Study the result. I bet you find C:\Program Files\nodejs in it.c:\program files\nodejs listing. That's where I see it on my system. If you don't see it there, then repeat the process in the "User Varables" section of the same dialog.
