# Fixing npm permissions | |
<iframe src="//www.youtube.com/embed/bxvybxYFq2o" frameborder="0" allowfullscreen></iframe> | |
You may receive an `EACCES` error when you try to install a package globally. This indicates that you do not have permission to write to the directories that npm uses to store global packages and commands. | |
You can fix this problem using one of two options: | |
1. Change the permission to npm's default directory. | |
1. Change npm's default directory to another directory. | |
You should back-up your computer before moving forward. | |
## 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 your path is `/usr`, switch to option 2. | |
2. Change the owner of npm's directory's to the effective name of the current user (your username!): | |
sudo chown -R `whoami` <directory> | |
If you don't want to change the permissions on the entire directory, you can change permissions on the subfolders `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; for example, if you are sharing a machine with other users. | |
In this case, you can configure npm to use a different directory. | |
1. Make a directory for global installations: | |
mkdir ~/npm-global | |
1. Configure npm to use the new directory path: | |
npm config set prefix '~/npm-global' | |
1. Open or create a `~/.profile` file and add this line: | |
export PATH=~/npm-global/bin:$PATH | |
1. Back on the command line, update your system variables: | |
source ~/.profile | |
Test: Download a package globally without using `sudo`. | |
npm install -g jshint |
