npm：如何重置node_modules前缀

Question

i installed node via homebrew. Since i had problems accessing the packages, i tried to change the node_modules prefix to user/local but made an error while typing the command:

npm config set prefix /usr/l    # See the typo there
                            ^

Now, whenever i run an npm command i get the following error:

$ npm config ls -l
Error: EACCES: permission denied, mkdir '/usr/l'
at Error (native)

i cannot set the prefix again ( npm config set prefix /usr/local ) , or even list the config ( npm config ls -l ) – all produce the same error as above. I tried re-installing node/npm.

How do i reset the prefix? Thanks.

If it is a permissions error, you should be able to use sudo to run it as root. This should take care of permission problems, which it appears to be in the error message
