Publishing to npm with Travis CI
<p>How do I publish to npm using Travis CI? I've tried the following .travis.yml:</p>

<pre><code>language: nodejs
node_js:
- '6'
- '6.1'
- '5.11'
before_script:
- npm install -g nodeunit
script: nodeunit
deploy:
  provider: npm
  email: my_email
  api_key: "encrypted"
</code></pre>

<p>But when it comes to the npm bit , I get:</p>

<pre><code>npm ERR! publish Failed PUT 400
npm ERR! Error: Not found : package-name
</code></pre>

<p>Any ideas?</p>

<p><strong>UPDATE</strong></p>

<p>With </p>

<pre><code>api_key:
   secure: "..." 
</code></pre>

<p>I get another error:</p>

<pre><code>NPM API key format changed recently. If your deployment fails, check your
API key in ~/.npmrc.
http://docs.travis-ci.com/user/deployment/npm/
~/.npmrc size: 53
env: &lt;this is my unencrypted api key&gt;: No such file or directory
</code></pre>

<p><strong>SOLUTION</strong></p>

<p>Finally solved it. The npm version on travis was really old (1.4.28). All I had to do was to put a :</p>

<pre><code>before_script:
- npm install -g npm@'&gt;=3'
</code></pre>

<p>And now it works!</p>
