<p>This command installs a package, and any packages that it depends on. If the
package has a package-lock or shrinkwrap file, the installation of dependencies
will be driven by that, with an <code class="language-text">npm-shrinkwrap.json</code> taking precedence if both
files exist. See <a href="../../configuring-npm/package-lock-json">package-lock.json</a> and <a href="../../cli-commands/npm-shrinkwrap"><code class="language-text">npm shrinkwrap</code></a>.</p>
<p>A <code class="language-text">package</code> is:</p>
<ul>
<li>a) a folder containing a program described by a <a href="../../configuring-npm/package-json"><code class="language-text">package.json</code></a> file</li>
<li>b) a gzipped tarball containing (a)</li>
<li>c) a url that resolves to (b)</li>
<li>d) a <code class="language-text"><name>@<version></code> that is published on the registry (see <a href="../../using-npm/registry"><code class="language-text">registry</code></a>) with (c)</li>
<li>e) a <code class="language-text"><name>@<tag></code> (see <a href="../../cli-commands/npm-dist-tag"><code class="language-text">npm dist-tag</code></a>) that points to (d)</li>
<li>f) a <code class="language-text"><name></code> that has a "latest" tag satisfying (e)</li>
<li>g) a <code class="language-text"><git remote url></code> that resolves to (a)</li>
</ul>
<p>Even if you never publish your package, you can still get a lot of
benefits of using npm if you just want to write a node program (a), and
perhaps if you also want to be able to easily install it elsewhere
after packing it up into a tarball (b).</p>
<ul>
<li>
<p><code class="language-text">npm install</code> (in package directory, no arguments):</p>
<p>Install the dependencies in the local node_modules folder.</p>
<p>In global mode (ie, with <code class="language-text">-g</code> or <code class="language-text">--global</code> appended to the command),
it installs the current package context (ie, the current working
directory) as a global package.</p>
<p>By default, <code class="language-text">npm install</code> will install all modules listed as dependencies
in <a href="../../configuring-npm/package-json"><code class="language-text">package.json</code></a>.</p>
<p>With the <code class="language-text">--production</code> flag (or when the <code class="language-text">NODE_ENV</code> environment variable
is set to <code class="language-text">production</code>), npm will not install modules listed in
<code class="language-text">devDependencies</code>. To install all modules listed in both <code class="language-text">dependencies</code>
and <code class="language-text">devDependencies</code> when <code class="language-text">NODE_ENV</code> environment variable is set to <code class="language-text">production</code>,
you can use <code class="language-text">--production=false</code>.</p>
<blockquote>
<p>NOTE: The <code class="language-text">--production</code> flag has no particular meaning when adding a
dependency to a project.</p>
</blockquote>
</li>
<li>
<p><code class="language-text">npm install <folder></code>:</p>
<p>Install the package in the directory as a symlink in the current project.
Its dependencies will be installed before it's linked. If <code class="language-text"><folder></code> sits
inside the root of your project, its dependencies may be hoisted to the
toplevel <code class="language-text">node_modules</code> as they would for other types of dependencies.</p>
</li>
<li>
<p><code class="language-text">npm install <tarball file></code>:</p>
<p>Install a package that is sitting on the filesystem. Note: if you just want
to link a dev directory into your npm root, you can do this more easily by
using <code class="language-text">npm link</code>.</p>
<p>Tarball requirements:</p>
<ul>
<li>The filename <em>must</em> use <code class="language-text">.tar</code>, <code class="language-text">.tar.gz</code>, or <code class="language-text">.tgz</code> as
the extension.</li>
<li>The package contents should reside in a subfolder inside the tarball (usually it is called <code class="language-text">package/</code>). npm strips one directory layer when installing the package (an equivalent of <code class="language-text">tar x --strip-components=1</code> is run).</li>
<li>The package must contain a <code class="language-text">package.json</code> file with <code class="language-text">name</code> and <code class="language-text">version</code> properties.</li>
</ul>
<p>Example:</p>
<div class="gatsby-highlight" data-language="text"><pre class="language-text"><code class="language-text"> npm install ./package.tgz</code></pre></div>
</li>
<li>
<p><code class="language-text">npm install <tarball url></code>:</p>
<p>Fetch the tarball url, and then install it. In order to distinguish between
this and other options, the argument must start with "http://" or "https://"</p>
<p>Example:</p>
<div class="gatsby-highlight" data-language="text"><pre class="language-text"><code class="language-text"> npm install https://github.com/indexzero/forever/tarball/v0.5.6</code></pre></div>
</li>
<li>
<p><code class="language-text">npm install [<@scope>/]<name></code>:</p>
<p>Do a <code class="language-text"><name>@<tag></code> install, where <code class="language-text"><tag></code> is the "tag" config. (See
<a href="../../using-npm/config"><code class="language-text">config</code></a>. The config's default value is <code class="language-text">latest</code>.)</p>
<p>In most cases, this will install the version of the modules tagged as
<code class="language-text">latest</code> on the npm registry.</p>
<p>Example:</p>
<div class="gatsby-highlight" data-language="text"><pre class="language-text"><code class="language-text"> npm install sax</code></pre></div>
</li>
<li>
<p><code class="language-text">npm install <alias>@npm:<name></code>:</p>
<p>Install a package under a custom alias. Allows multiple versions of
a same-name package side-by-side, more convenient import names for
packages with otherwise long ones and using git forks replacements
or forked npm packages as replacements. Aliasing works only on your
project and does not rename packages in transitive dependencies.
Aliases should follow the naming conventions stated in
<a href="https://www.npmjs.com/package/validate-npm-package-name#naming-rules"><code class="language-text">validate-npm-package-name</code></a>.</p>
<p>Examples:</p>
<div class="gatsby-highlight" data-language="text"><pre class="language-text"><code class="language-text"> npm install my-react@npm:react
npm install jquery2@npm:jquery@2
npm install jquery3@npm:jquery@3
npm install npa@npm:npm-package-arg</code></pre></div>
<p><code class="language-text">npm install</code> saves any specified packages into <code class="language-text">dependencies</code> by default.
Additionally, you can control where and how they get saved with some
additional flags:</p>
<ul>
<li><code class="language-text">-P, --save-prod</code>: Package will appear in your <code class="language-text">dependencies</code>. This is the
default unless <code class="language-text">-D</code> or <code class="language-text">-O</code> are present.</li>
<li><code class="language-text">-D, --save-dev</code>: Package will appear in your <code class="language-text">devDependencies</code>.</li>
<li><code class="language-text">-O, --save-optional</code>: Package will appear in your <code class="language-text">optionalDependencies</code>.</li>
<li><code class="language-text">--no-save</code>: Prevents saving to <code class="language-text">dependencies</code>.</li>
</ul>
<p>When using any of the above options to save dependencies to your
package.json, there are two additional, optional flags:</p>
<ul>
<li><code class="language-text">-E, --save-exact</code>: Saved dependencies will be configured with an
exact version rather than using npm's default semver range
operator.</li>
<li><code class="language-text">-B, --save-bundle</code>: Saved dependencies will also be added to your <code class="language-text">bundleDependencies</code> list.</li>
</ul>
<p>Further, if you have an <code class="language-text">npm-shrinkwrap.json</code> or <code class="language-text">package-lock.json</code> then it
will be updated as well.</p>
<p><code class="language-text"><scope></code> is optional. The package will be downloaded from the registry
associated with the specified scope. If no registry is associated with
the given scope the default registry is assumed. See <a href="../../using-npm/scope"><code class="language-text">scope</code></a>.</p>
<p>Note: if you do not include the @-symbol on your scope name, npm will
interpret this as a GitHub repository instead, see below. Scopes names
must also be followed by a slash.</p>
<p>Examples:</p>
<div class="gatsby-highlight" data-language="bash"><pre class="language-bash"><code class="language-bash"><span class="token function">npm</span> <span class="token function">install</span> sax
<span class="token function">npm</span> <span class="token function">install</span> githubname/reponame
<span class="token function">npm</span> <span class="token function">install</span> @myorg/privatepackage
<span class="token function">npm</span> <span class="token function">install</span> node-tap --save-dev
<span class="token function">npm</span> <span class="token function">install</span> dtrace-provider --save-optional
<span class="token function">npm</span> <span class="token function">install</span> readable-stream --save-exact
<span class="token function">npm</span> <span class="token function">install</span> ansi-regex --save-bundle</code></pre></div>
<p><strong>Note</strong>: If there is a file or folder named <code class="language-text"><name></code> in the current
working directory, then it will try to install that, and only try to
fetch the package by name if it is not valid.</p>
</li>
<li>
<p><code class="language-text">npm install [<@scope>/]<name>@<tag></code>:</p>
<p>Install the version of the package t
