NPM

Resolving EACCES permissions errors when installing packages globally

Back up your computer.
On the command line, in your home directory, create a directory for global installations:
```
 mkdir ~/.npm-global
```
Configure npm to use the new directory path:
```
 npm config set prefix '~/.npm-global'
```
In your preferred text editor, open or create a ~/.profile file and add this line:
```
 export PATH=~/.npm-global/bin:$PATH
```
On the command line, update your system variables:
```
 source ~/.profile
```
To test your new configuration, install a package globally without using sudo:
```
 npm install -g jshint
```
