npm err code eisdir errno -4068 whenever installing any package - node.js

Question

I followed this guide to install node to my machine without having admin rights.
I put node.exe, (npm.cmd and node_modules ) both from the npm zip in C:\Users\rakibler\Node. I added that to my path. I ran npm install -g bower and got
npm ERR! Error: EISDIR, open 'C:\Users\rakibler\Node\bower'
npm ERR! at Error (native)
npm ERR! If you need help, you may report this *entire* log,

at the end. It also seems like something else is wrong, because everything it downloads goes to C:\Users\rakibler\Node instead of C:\Users\rakibler\Node\node_modules. Not sure what's going wrong here. Any idea?

Answer 1

i think you need to install the npm globlally using
"npm install -g npm"
and then use it in directory to install bower . i hope this will solve your issue
