I'm trying to update my version of node to the latest stable.

Using this resource I was able to:

sudo npm install n -g

But when I try

sudo npm n stable

I get:

sudo: n: command not found

If I run n stable, the command is present:

n stable
mkdir: cannot create directory ‘/usr/local/n’: Permission denied
mkdir: cannot create directory ‘/usr/local/n’: Permission denied
mkdir: cannot create directory ‘/usr/local/n’: Permission denied
mkdir: cannot create directory ‘/usr/local/n’: Permission denied

     install : node-v0.12.2
       mkdir : /usr/local/n/versions/node/0.12.2
mkdir: cannot create directory ‘/usr/local/n’: Permission denied

  Error: sudo required
  • Nice idea, but when I do that it returns me 'n: command not found', even though I've dropped the 'sudo' – JonRed Apr 13 '15 at 8:15
  • sudo sh -c "PATH=$PATH; n stable" <new line> sh: 1: n: not found – JonRed Apr 13 '15 at 8:19
  • No output at all. That's depresssing :-( – JonRed Apr 13 '15 at 8:20
  • Let us continue this discussion in chat. – JonRed Apr 13 '15 at 8:21
  • Please post the output of ls /usr/local/bin/n – Helio Apr 13 '15 at 8:41

Surprisingly, your npm installation has the global prefix in a folder called npm on your home directory, this means that any package installed with the -g flag will install on this folder.

You can change this folder to any folder that is on the sudo safe path following these steps:

Graphical way:

  1. Open a File Manager (a.k.a Nautilus).
  2. Navigate to your home folder.
  3. Press Ctrl+H to show hidden files.
  4. Open a file called .npmrc with your favorite text editor.
  5. Find a line on that file with this content:

  6. Replace /home/<your_username>/npm by a safe path (such as /usr/local/bin).
  7. Once replaced it will look like this:

  8. Save the file.
  9. Run again sudo npm install n -g

Terminal way:

Run this command:

sed -i.bak "s%^prefix=.*$%prefix=/usr/local/bin%" ~/.npmrc
  • I think this nailed it! It also helped me just now when I updated my npm version, but wouldn' t recognise it. So, accepted, and thank you! – JonRed Apr 19 '15 at 19:19
  • Didnt help, still same isssue :/ – Luckylooke Jul 6 '15 at 14:53
  • This helped me! I didn't have ~/.npmrc file, so I added it and now it works fine – Kirill Gusyatin Sep 6 '16 at 12:10

    Beware: this will undo Option 2 of fixing NPM permissions – Edson Horacio Junior Jan 10 '17 at 21:55

I have found solution which worked for me:

sudo -E env "PATH=$PATH" n stable

Found it here: https://stackoverflow.com/a/29400598/861615

  • env: n: No such file or directory – user3311522 Jul 15 '16 at 19:10
  • @user3311522 did you use: sudo npm install n -g before sudo -E env "PATH=$PATH" n stable ?? – Luckylooke Jul 17 '16 at 19:13

I know this is an Ubuntu forum, but I'm sure this will help someone with the same problem on the RHEL flavours who Googled to here like I did. Perhaps it also works in Ubuntu.

This is the approach:

ln -s /usr/local/bin/n /usr/bin/n

To avoid messing up with the .npm-global folder as noted by @Edson Horacio Junior, and based on @pohest's answer, here is how I fixed it:

sudo ln -s /home/<username>/.npm-global/bin/n /usr/local/bin/n
sudo n --version # test it

As a note, this probably will not work if you haven't followed npm's steps for changing the default global directory.


I found a solution that worked for me. Use nvm package to download latest node.

  1. Install nvm using below command

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash

  1. Create an environment variable to use nvm
export NVM_DIR="${XDG_CONFIG_HOME/:-$HOME/.}nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
  1. Try nvm -v if it cannot see nvm installed, run the script below

command -v nvm

  1. To install node run command below

nvm install node

  1. After restarting the terminal, try to check the version of node, it should be updated

node -v
