| <div id="_content"><h3 id="description">Description</h3> |
| <p>To publish and install packages to and from the public npm registry, you |
| must install Node.js and the npm command line interface using either a Node |
| version manager or a Node installer. <strong>We strongly recommend using a Node |
| version manager to install Node.js and npm.</strong> We do not recommend using a |
| Node installer, since the Node installation process installs npm in a |
| directory with local permissions and can cause permissions errors when you |
| run npm packages globally.</p> |

| </ul> |
| <h3 id="checking-your-version-of-npm-and-nodejs">Checking your version of npm and Node.js</h3> |
| <p>To see if you already have Node.js and npm installed and check the |
| installed version, run the following commands:</p> |
| <pre><code>node -v |
| npm -v |
| </code></pre> |
| <h3 id="using-a-node-version-manager-to-install-nodejs-and-npm">Using a Node version manager to install Node.js and npm</h3> |
| <p>Node version managers allow you to install and switch between multiple |
| versions of Node.js and npm on your system so you can test your |
| applications on multiple versions of npm to ensure they work for users on |
| different versions. You can |
| <a href="https://github.com/search?q=node+version+manager+archived%3Afalse&type=repositories&ref=advsearch">search for them on GitHub</a>.</p> |
| <h3 id="using-a-node-installer-to-install-nodejs-and-npm">Using a Node installer to install Node.js and npm</h3> |
| <p>If you are unable to use a Node version manager, you can use a Node |
| installer to install both Node.js and npm on your system.</p> |
| <ul> |
| <li><a href="https://nodejs.org/en/download/">Node.js installer</a></li> |
| <li><a href="https://github.com/nodesource/distributions">NodeSource installer</a>. If |

| </ul> |
| <h4 id="os-x-or-windows-node-installers">OS X or Windows Node installers</h4> |
| <p>If you're using OS X or Windows, use one of the installers from the |
| <a href="https://nodejs.org/en/download/">Node.js download page</a>. Be sure to |
| install the version labeled <strong>LTS</strong>. Other versions have not yet been |
| tested with npm.</p> |
| <h4 id="linux-or-other-operating-systems-node-installers">Linux or other operating systems Node installers</h4> |
| <p>If you're using Linux or another operating system, use one of the following |
| installers:</p> |
| <ul> |
| <li><a href="https://github.com/nodesource/distributions">NodeSource installer</a> |
| (recommended)</li> |
| <li>One of the installers on the <a href="https://nodejs.org/en/download/">Node.js download |
| page</a></li> |
| </ul> |
| <p>Or see <a href="https://nodejs.org/en/download/package-manager/">this page</a> to |
| install npm for Linux in the way many Linux developers prefer.</p> |
