Running npm install -g yo command gives -> ERR

Question

I just tried to do a npm install but get this error.

npm install -g yo
npm ERR! Error: EACCES, mkdir '/usr/local/lib/node_modules/yo'

I changed the permissions of /usr/local with chown, but I'm not sure if this affects my issue. How can i fix it?

Edit

Ah, I read your OS wrong, you're on a mac. I'll leave this here though as it might still work (assuming you installed node via Homebrew)

---

I've only recently been playing with npm on Linux and this is how I solved it...

First, set the global npm prefix to a local (to your user) install

mkdir ~/.node && npm config set prefix ~/.node

npm up to and including version 1.4.20 is buggy (it ignores prefix configuration) so first thing we're going to do is install the current npm local to your user.

npm install -g --prefix=~/.node npm

Now all that's left to do is update your environment variables. In ~/.bashrc or whatever your preference is...

if [ -d "$HOME/.node/bin" ]; then
    PATH="$HOME/.node/bin:$PATH"
fi

export NODE_PATH="$NODE_PATH:$HOME/.node/lib/node_modules"

Then source it and you're good to go

source ~/.bashrc

Answer 3

try with

sudo mkdir -p /usr/local/lib/node_modules
sudo chown -R $USER /usr/local/lib/node_modules
npm install -g yo
