Permission denied when installing npm modules in OSX

Question

I'm trying to install node-g.raphael, and I'm getting the following error:

Bender-03:htdocs alfred$ sudo npm install node-g.raphael --save
Password:

> contextify@0.1.15 install

+ node-g.raphael@0.0.9
added 2 packages and updated 1 package in 6.556s

I've tried this solution, but it doesn't solve my problem, still getting the same error.

Let me know if there's anything I can add to help in solving this.

Answer 1

Change the ownership of .npm by using the command sudo chown -R $(whoami) ~/.npm

Answer 2

Brew uninstall node 
Brew install node 

create a link if there is an error and if link doesn't work do the following Simply run these four commands:

  sudo chown -R `whoami`:admin /usr/local/include/node
    sudo chown -R `whoami`:admin /usr/local/bin
    sudo chown -R `whoami`:admin /usr/local/share
    sudo chown -R `whoami`:admin /usr/local/lib/dtrace 

Finally, run the overwrite command:

brew link --overwrite node

Saw this from Fixing npm permissions and it helped, maybe you could give it a shot as well.

Option 1: Change the permission to npm's default directory

1. Find the path to npm's directory:

   npm config get prefix

For many systems, this will be /usr/local.

WARNING: If the displayed path is just /usr, switch to Option 2 or you will mess up your permissions.

2. Change the owner of npm's directories to the name of the current user (your username):

   sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}

This changes the permissions of the sub-folders used by npm and some other tools (lib/node_modules, bin, and share).

Option 2: Change npm's default directory to another directory

There are times when you do not want to change ownership of the default directory that npm uses (i.e. /usr) as this could cause some problems, for example if you are sharing the system with other users.

Instead, you can configure npm to use a different directory altogether. In our case, this will be a hidden directory in our home folder.

1. Make a directory for global installations:

   mkdir ~/.npm-global

2. Configure npm to use the new directory path:

   npm config set prefix '~/.npm-global'

3. Open or create a ~/.profile file and add this line:

   export PATH=~/.npm-global/bin:$PATH

4. Back on the command line, update your system variables:

   source ~/.profile

Test: Download a package globally without using sudo.

`npm install node-g.raphael --save`

Instead of steps 2-4, you can use the corresponding ENV variable (e.g. if you don't want to modify ~/.profile):

NPM_CONFIG_PREFIX=~/.npm-global

Option 3: Use a package manager that takes care of this for you.

If you're doing a fresh install of Node on Mac OS, you can avoid this problem altogether by using the Homebrew package manager. Homebrew sets things up out of the box with the correct permissions.

brew install node

Answer 4

Rather than changing your file permissions and risking confusion within your system (what I have done and may live to regret at a later date), may I suggest the following that I found after the fact.

Answer 5

To get access on Mac/Linux, simply use this command

sudo npm install -g {package_name}

And you are good to go.

Answer 6

I use:

1. npm config get prefix
2. sudo chown -R $(whoami) $(npm config get prefix)/{lib/node_modules,bin,share}
3. sudo npm install

Answer 7

Issue fixed for me by running the below command.

sudo npm install -g @angular/cli

Was able to install angular.

Then try running ng -v to confirm.
