node.js - Run npm as superuser, it isn't a good idea? -


i'm getting errors npm while trying install/update packages without su permissions on linux.

the easy way solve problem execute sudo npm install <package>, i'm not sure if idea.

best way become owner of .npm folder, found stackoverflow's questions , blog posts.

my question is: why run npm su isn't idea?

running npm super user has risk of running untrusted code super user can potentially mess entire system. running npm unprivileged user has risk of running code less privileges , won't able mess entire system - own files (which can equally bad, depending on how @ it).

what , recommend install node in home directory instead of globally on system if it's own computer. way don't have run sudo or su npm or make install of node itself.

i run lot of versions of node compile sources different switches , convention use install node in versioned directories, either globally in /opt (but need sudo) or locally in home directory in ~/opt.

i this:

wget https://nodejs.org/dist/v7.1.0/node-v7.1.0.tar.gz tar xzvf node-v7.1.0.tar.gz cd node-v7.1.0 ./configure --prefix=$home/opt/node-v7.1.0 make && make test && make install

then create symlink ~/opt/node pointing ~/opt/node-v7.1.0 , have:

path="$home/opt/node/bin:$path"

in .profile or .bashrc.

that way don't have run super user installing node or running npm.

as bonus can switch default node version changing symlink, , @ time can run other version if change path or run node full path ~/opt/node-v7.0.0/bin/node.

i explained installation process in more detail in other answers:

i don't want go detail here since answer why running npm superuser not idea - installation process 1 solution not have run npm superuser.

other options of setting npm permissions avoid running superuser described in fixing npm permissions in npm docs (thanks ryanzim pointing out in comments).
