Answer 2

Well, I used --save-dev and installed it not globally or using -g, the main problem occurs while you want it to write on default node_modules folder.

It solved my problem after 4 hours of checking multiple issues.

I even suggest you to use the npm init and make a package.json for a better dependency checking and then run npm install afterward. this video helps you for this https://www.youtube.com/watch?v=rTsz09zRuTU

Answer 3

add following lines to ~/.bashrc after installing npm:

npm set prefix ~/.npm
PATH="$HOME/.npm/bin:$PATH"
PATH="./node_modules/.bin:$PATH"

Execute following line after changes:

source ~/.bashrc

and as mentioned by @contemplator avoid using sudo

Answer 4

Note: It is highly recommended to avoid using sudo with npm!

Using sudo is not recommended. It may give you permission issue later. While the above works, use these instructions to fix your issue permanently.

Answer 5

An inadvisable way to fix the issue would be to use sudo:

sudo npm install -g monaca

However it would be better to find a way around this without using sudo.

npm install -g less does not work
