I have node and npm with existing packages currently installed to the C drive on Windows. My C drive is an SSD with a low amount of space. How can I move the node installation to a different drive? Would I need to reinstall node and all packages? The current node installer doesn't seem to specify drives.
You can move the node.exe to the d drive. Then check your environment path. Type set in a command window or in computer properties. Make sure you have the folder that contains node.exe in your path. Running node in a command window will work from any folder then.
For installed npm packages, ie.. node_modules folder.. That just needs to be in a directory above where your writing your code, so try putting that folder in d:\ Assuming your going to be writing your apps on the d drive now.
In .npmrc file, change prefix setting to desired folder. Global packages get installed in node_modules under that folder
I'm not sure what you are talking about, the node installer has this page. 
What version of node are you trying to install? This screenshot is taken from v 11.7 of node.
