I attempted to change the permissions of /usr/local using chown, but I am unsure if it has resolved my issue. What steps should I take to fix it?

Update

Oops, seems like I misread your operating system; you're actually on a Mac. However, feel free to try out the following steps as they might still be effective (assuming node was installed via Homebrew).

I recently dabbled with npm on Linux and here's how I managed to resolve it...

To start, adjust the global npm prefix for a local user installation:

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

Note that npm versions up to 1.4.20 can be glitchy (due to ignoring prefix configuration), so initially, we'll install the latest npm for your user's environment.

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

Finally, update your environment variables in a file like ~/.bashrc or any preferred location...

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

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

Ensure to source it afterward and you should be good to proceed

source ~/.bashrc

Answer №2

For an explanation on why the command below should be effective, refer to this hyperlink

sudo npm install -g yo

Answer №3

experiment using

run this in your terminal:
sudo mkdir -p /usr/local/lib/node_modules
sudo chown -R $USER /usr/local/lib/node_modules
npm install -g yo
