<h1><a href="../files/npmrc.html">npmrc</a></h1> <p>The npm config files</p>
|
|
|
|
|
<h2 id="description">DESCRIPTION</h2>
|
|
|
|
|
<p>npm gets its config settings from the command line, environment
|
|
|
|
|
variables, and <code>npmrc</code> files.</p>
|
|
|
|
|
<p>The <code>npm config</code> command can be used to update and edit the contents
|
|
|
|
|
of the user and global npmrc files.</p>
|
|
|
|
|
<p>For a list of available configuration options, see <a href="../misc/npm-config.html">npm-config(7)</a>.</p>
|
|
|
|
|
<h2 id="files">FILES</h2>
|
|
|
|
|
<p>The four relevant files are:</p>
|
|
|
|
|
<ul>
|
|
|
|
|
<li>per-project config file (/path/to/my/project/.npmrc)</li>
|
|
|
|
|
<li>per-user config file (~/.npmrc)</li>
|
|
|
|
|
<li>global config file ($PREFIX/npmrc)</li>
|
|
|
|
|
<li>npm builtin config file (/path/to/npm/npmrc)</li>
|
|
|
|
|
</ul>
|
|
|
|
|
<p>All npm config files are an ini-formatted list of <code>key = value</code>
|
|
|
|
|
parameters. Environment variables can be replaced using
|
|
|
|
|
<code>${VARIABLE_NAME}</code>. For example:</p>
|
|
|
|
|
<pre><code>prefix = ${HOME}/.npm-packages
|
|
|
|
|
</code></pre><p>Each of these files is loaded, and config options are resolved in
|
|
|
|
|
priority order. For example, a setting in the userconfig file would
|
|
|
|
|
override the setting in the globalconfig file.</p>
|
|
|
|
|
<p>Array values are specified by adding "[]" after the key name. For
|
|
|
|
|
example:</p>
|
|
|
|
|
<pre><code>key[] = "first value"
|
|
|
|
|
key[] = "second value"
|
|
|
|
|
</code></pre><h3 id="per-project-config-file">Per-project config file</h3>
|
|
|
|
|
<p>When working locally in a project, a <code>.npmrc</code> file in the root of the
|
|
|
|
|
project (ie, a sibling of <code>node_modules</code> and <code>package.json</code>) will set
|
|
|
|
|
config values specific to this project.</p>
|
|
|
|
|
<p>Note that this only applies to the root of the project that you're
|
|
|
|
|
running npm in. It has no effect when your module is published. For
|
|
|
|
|
example, you can't publish a module that forces itself to install
|
|
|
|
|
globally, or in a different location.</p>
|
|
|
|
|
<h3 id="per-user-config-file">Per-user config file</h3>
|
|
|
|
|
<p><code>$HOME/.npmrc</code> (or the <code>userconfig</code> param, if set in the environment
|
|
|
|
|
or on the command line)</p>
|
|
|
|
|
<h3 id="global-config-file">Global config file</h3>
|
|
|
|
|
<p><code>$PREFIX/etc/npmrc</code> (or the <code>globalconfig</code> param, if set above):
|
|
|
|
|
This file is an ini-file formatted list of <code>key = value</code> parameters.
|
|
|
|
|
Environment variables can be replaced as above.</p>
|
|
|
|
|
<h3 id="built-in-config-file">Built-in config file</h3>
|
|
|
|
|
<p><code>path/to/npm/itself/npmrc</code></p>
|
|
|
|
|
<p>This is an unchangeable "builtin" configuration file that npm keeps
|
|
|
|
|
consistent across updates. Set fields in here using the <code>./configure</code>
|
|
|
|
|
script that comes with npm. This is primarily for distribution
|
|
|
|
|
maintainers to override default configs in a standard and consistent
|
|
|
|
|
manner.</p>
