How to change the npm prefix without config?

问题:

I accidentally changed the npm prefix to a place that doesn't exist. Is there a configuration file I can access that would allow me to change this back?

The only options I can think of are:

1. Completely Uninstall Node (npm not responding after changing the prefix)
2. I guess I could create the directories that don't exist and move the npm files there.

But it seems like there should be a config file I can change somewhere, right?

回答1:

prefix can be defined per-install and other commands using --prefix, but as a global setting it is in ~/.npmrc (C:\Users\<your user name>\.npmrc). You can remove / edit it directly in that file.

You can also use npm config set prefix $value, or npm config delete prefix if you prefer.
